You have decided to hire a backend engineer from Indonesia. Now the question: which stack?
Most hiring guides will tell you what languages are globally popular. What they will not tell you is how that translates specifically to the Indonesian developer pool — where the depth is, where it thins out, and what to expect when you hire for each stack.
This article gives you that breakdown. We cover Node.js, Python, Go, and TypeScript: global demand data, Indonesian developer reality, what RainTech sees in our pre-vetting process, and how to calibrate your expectations before you post a role.
The Global Stack Context in 2026
Before the Indonesia-specific breakdown, the global baseline — because the stacks your Indonesian engineers work in are the same ones driving the international market they are competing in.
According to the Stack Overflow Developer Survey 2025 (31,771 responses globally):
- JavaScript/Node.js: 66% of all developers, 68.8% of professional developers. Node.js remains the most used web framework — though its peak was 51% in 2020 and it has plateaued since.
- Python: 57.9% of all developers, up 7 percentage points from 2024 — the largest single-year jump of any major language. Driven by AI, data science, and FastAPI's rise as a backend framework.
- TypeScript: 43.6% of all developers. On GitHub, TypeScript overtook Python and JavaScript to become the #1 language by contributor count in August 2025 (GitHub Octoverse 2025).
- Go: 16.4% of all developers, 17.4% of professional developers. Average salary for Go developers globally: $146,879 — one of the highest of any language.
These are not niche stacks. They are the backbone of modern international product engineering — which is exactly what Indonesian developers building for global companies are working in.
Node.js: Deep Pool, Variable Quality
Global Demand
High and stable. Node.js powers APIs, real-time applications, and microservices at companies from Netflix to Shopify. The JavaScript ecosystem means frontend engineers can transition to Node.js backend work, which broadens the available pool.
Indonesian Developer Reality
Node.js has the deepest developer pool in Indonesia. It is taught widely at Indonesian universities and bootcamps, used extensively at Indonesian startups (GoTo, Tokopedia, Bukalapak all use JavaScript-heavy stacks), and well-represented in the Indonesian open source community.
What This Means for You
- Junior to mid-level (Tier 1–2): Large pool, relatively fast to source. Expect candidates with 1–4 years of Node.js production experience, typically in REST API development, Express/Fastify, and basic async patterns.
- Senior level (Tier 3+): Quality rises sharply with experience screening. Genuine Node.js depth — event loop mastery, performance optimization, high-throughput API design — requires more rigorous vetting.
What RainTech Looks for in Node.js Candidates
Beyond "has used Express," we assess understanding of async/await patterns and callback handling, experience with streaming, production debugging at scale, and test coverage discipline. Many candidates list Node.js; fewer have built systems that handle real load.
Hire Node.js From Indonesia if:
- You need an API layer or microservice built fast.
- Your team uses a JavaScript-first stack (React frontend + Node backend).
- You are comfortable doing a deeper technical screen for senior roles.
Typical Salary Range (RainTech's Tiers)
- Tier 2 Mid-level (3–5 years): $1,200–$2,000/month.
- Tier 3 Senior (5+ years): $2,000–$3,000/month.
Phyton: Growing Fast, Especially for Backend and AI
Global Demand
Surging. Python's 7-percentage-point jump in the Stack Overflow 2025 survey reflects its expansion beyond data science into general backend development — particularly through Django and the rapidly growing Fast API framework, which saw a 5-point usage increase from 2024 to 2025.
Indonesian Developer Reality
Python has grown significantly in Indonesia over the past 3–4 years, driven by two trends: the AI/ML wave pulling developers toward Python-based frameworks, and the startup ecosystem adopting Python for rapid backend prototyping with Django and Flask.
The Indonesian Python pool is not as deep as Node.js, but the quality floor is often higher. Developers who have invested in Python typically have stronger computer science fundamentals, because Python is the dominant language in Indonesian university data science and AI programmes.
What This Means for You
- Data science / ML: Good depth at mid to senior level. Indonesian universities have expanded Python-based data science curricula, and the AI wave has pulled many Indonesian engineers toward Python for the first time.
- Backend API (Django/Fast API): Solid mid-level pool. Senior Django engineers with production-scale experience are less common and take longer to source.
- General scripting / automation: Very common. Many Indonesian developers use Python as a secondary language alongside JavaScript.
What RainTech Looks for in Phyton Candidates
OOP understanding, experience with async frameworks (Fast API vs Flask vs Django's sync model), database query optimization in ORM-heavy codebases, and — for AI-adjacent roles — practical PyTorch or scikit-learn experience beyond tutorial projects.
Hire Phyton from Indonesia if:
- You are building data pipelines, ML inference APIs, or AI-adjacent backend systems.
- You want FastAPI for high-performance async APIs.
- You are comfortable with a slightly smaller pool and longer sourcing time for senior roles.
Typical Salary Range (RainTech's Tiers)
- Tier 2 Mid-level: $1,200–$2,000/month.
- Tier 3 Senior: $2,000–$3,000/month.
- Tier 4 Staff/Principal (AI/ML specialisation): $3,000+/month.
Go: Small but High-Quality Pool
Global Demand
Growing, particularly in cloud-native and infrastructure engineering. Go is the language of Kubernetes, Docker, and many high-performance API services. Companies like Uber, Netflix, and Cloudflare use Go for performance-critical backend work. Average Go developer salary globally ($146,879) is one of the highest of any backend language, reflecting genuine scarcity.
Indonesian Developer Reality
Go's Indonesian developer pool is smaller than Node.js or Python — but the engineers in that pool tend to be high-quality, self-selected individuals who pursued Go deliberately rather than because it was the path of least resistance.
Most Indonesian Go developers have backgrounds in Java or C++ before transitioning, and many have worked at Indonesian unicorns or international tech companies that run Go-based services. The pool is concentrated in Jakarta and Bandung, typically at the senior end.
What This Means for You
- Sourcing time: Longer than Node.js or Python — 3–4 weeks for a verified senior Go engineer versus 1–2 weeks for Node.js equivalents.
- Quality when found: Generally very high. Go developers who have built production systems in Indonesia have usually done so at real scale.
- Microservices and gRPC: Good representation at senior level, particularly in companies that have adopted cloud-native architecture.
What RainTech Looks for in Go Candidates
Goroutine and channel patterns, interface design, profiling and performance optimisation, and experience with gRPC or protocol buffers for service-to-service communication. Go's concurrency model is where juniors typically fall short.
Hire Go From Indonesia if:
- You are building high-performance microservices, infrastructure tooling, or cloud-native backend systems.
- You have 3–4 weeks for sourcing and can afford to be selective.
- Your technical bar is high and you are willing to pay at the top of Tier 3 or Tier 4 range.
Typical Salary Range (RainTech's Tiers)
- Tier 3 Senior (5+ years Go specifically): $2,500–$3,000/month.
- Tier 4 Staff/Principal: $3,000+/month.
TypeScript: The Emerging Standard
Global Demand
TypeScript is now the default for serious JavaScript/Node.js projects at most international tech companies. According to GitHub Octoverse 2025, TypeScript became the #1 language by contributor count in August 2025 — overtaking both Python and JavaScript. Stack Overflow 2025 shows TypeScript at 43.6% usage among all developers, and 48.8% among professional developers.
Indonesian Developer Reality
TypeScript adoption in Indonesia has followed global trends — accelerated by framework defaults (Next.js, NestJS, and most modern frontend tooling now scaffold in TypeScript by default) and by the influence of international companies hiring Indonesian developers who require TypeScript.
Mid-to-senior Indonesian engineers who have worked with international teams in the last 2–3 years almost universally have TypeScript experience. It is increasingly rare to find a Node.js developer at Tier 2+ who does not also know TypeScript.
Practical Implication
If you are hiring Node.js developers, default to requiring TypeScript — the pool of engineers who know both is large, and the pool of Node.js engineers without TypeScript is increasingly composed of those who have not worked with international teams (a signal in itself).
Indonesia Tech Stack Comparison (2026)
| Factor | Node.js | Python | Go | TypeScript |

| Typical Salary | $2,000–$3,000/mo | $2,000–$3,000/mo | $2,500–$3,000/mo | $2,000–$3,000/mo |
What RainTech's Vetting Process Tells Us
Numbers on a CV do not tell the full story for any of these stacks. RainTech's co-founder Veri Ferdiansyah — former CTO and VP of Engineering at multiple Indonesian startups — personally leads the technical screening of every candidate. Here is what we consistently see across stacks:
The Most Common Gap
Candidates who have used a framework extensively without understanding what the framework is abstracting. A Node.js developer who has only worked within Express but cannot reason about the event loop. A Python developer who uses Django ORM but cannot write a raw SQL query. A Go developer who uses goroutines but does not understand when not to use them.
The Signal We Look for
Production systems. Engineers who have shipped something real — that has real users, real load, real debugging — consistently outperform engineers whose experience is primarily bootcamp projects or tutorial codebases. We ask for specific production systems in every technical screen, not algorithm puzzles.
The Global Readiness Layer
Beyond technical competence, we assess async communication skills and cultural adaptability — because working with an international team requires more than code. An engineer who is technically strong but cannot write a clear async Slack update will slow your team down despite their skills.
This is the screening layer that global EOR platforms like Deel and Remote.com do not provide. When you hire through RainTech, the shortlist you receive has already passed both technical and global-readiness vetting.
FAQs
Is the Indonesian Node.js developer pool large enough to hire senior engineers?
Yes — but senior quality requires more rigorous vetting than junior or mid-level. The pool is large; the genuinely senior segment requires screening beyond framework familiarity. RainTech's pre-vetting process specifically filters for production-scale Node.js experience, not just years of usage.
Are Indonesian Python developers good for AI and machine learning roles?
Growing rapidly. Indonesian university data science programmes have expanded significantly, and the AI wave has pulled many strong engineers toward Python-based ML frameworks. For practical ML engineering (model deployment, inference APIs, data pipelines), Indonesia now has a solid mid-to-senior pool. For cutting-edge research roles, the pool is thinner.
How long does it take to source a Go developer in Indonesia?
Typically 3–4 weeks from brief confirmation to shortlist presentation. The pool is smaller than Node.js or Python, so sourcing takes longer — but the quality when found is generally high. If your role requires Go, factor this into your timeline.
Should I require TypeScript when hiring Node.js developers from Indonesia?
Yes, for Tier 2+ roles. Most mid-to-senior Indonesian Node.js developers who have worked with international teams already use TypeScript as standard. Requiring TypeScript narrows the pool slightly but is a useful quality filter — engineers without TypeScript experience have typically not worked in international-standard codebases.
What if I need a fullstack engineer who knows both Node.js and Python?
These engineers exist in Indonesia — particularly those who have worked at startups that use Python for data/ML and Node.js for APIs. They are less common than pure specialists, and the sourcing timeline is 3–4 weeks. Share your full stack requirements with RainTech upfront so we can filter accurately from our pre-vetted pool.
