Ho Chi Minh City Vietnam Spartan Dev Full time $120,000 - $200,000 per year

Build like a founder. Ship like Spartan.

Spartan is where world-class engineers build world-class startups. Our customers are scaling fast — and so are we. That's why we're looking for an Engineering Intern to join our team and get hands-on experience working with cutting-edge startups.

At Spartan, we don't act like vendors. We embed with startups backed by YC, Pear VC, a16z, Techstars, and more — partnering with founders and engineers from Stanford, MIT, Yale, Google, Amazon, Uber, and beyond. Together, we help launch MVPs in 30 days and scale systems that power millions of users.

This isn't "fetch coffee and file tickets." As an intern at Spartan, you'll work on real projects — whether that's backend services, frontend apps, AI workflows, or DevOps — and learn directly from engineers who've scaled companies to IPO.

You'll also get a front-row seat to the future of AI: 70% of our portfolio today is LLM-powered. Our engineers leverage the latest tools like Cursor, Claude, and Codex to accelerate development and integrate AI-native workflows into everything we build.

What You'll Do

  • Contribute to real production projects for US-based startups.
  • Learn and build in one or more areas:
    • Backend (APIs, databases, cloud infra, distributed systems)
    • Frontend (React, TypeScript, , UI/UX)
    • AI/LLM (RAG pipelines, vector DBs, evals, guardrails)
    • DevOps/Infra (CI/CD, Kubernetes, observability)
  • Ship features end-to-end with mentorship from senior Spartan engineers.
  • Participate in our proven process: async standups, PRDs/RFCs, code reviews, testing.
  • Experiment with AI-native tooling (Cursor, Claude, Codex) to boost your workflow.

What We're Looking For

  • Strong English communication — you'll collaborate directly with US-based teams.
  • Pursuing a degree in Computer Science (or equivalent) OR recent graduate.
  • Solid foundation in at least one area: algorithms, data structures, databases, or web dev.
  • Familiarity with modern programming languages (TypeScript, Python, Go, Java/Kotlin, etc.).
  • Curiosity and eagerness to learn fast — a builder's mindset.

Tech You'll Touch (depending on your track)

  • Frontend: React
    • TypeScript
    •
    • TailwindCSS
  • Backend:
    • Python
    • Go
    • Kotlin
    • Postgres
    • Redis
  • Infra/DevOps: AWS
    • GCP
    • Docker
    • Kubernetes
    • CI/CD
  • AI/LLM: Vector DBs
    • RAG pipelines
    • Guardrails
    • Cursor
    • Claude
    • Codex

Perks & Benefits

  • Real startup experience — not classroom projects
  • Mentorship from engineers who've scaled companies from 0 → IPO
  • Exposure to top-tier US startups (YC, a16z, Techstars, Pear VC)
  • Flexible hours + hybrid style
  • Team events and Spartan culture (monthly parties, annual trip)
  • Potential return offer for top performers

Why Spartan?

  • 50+ MVPs launched, 3 IPOs, $100M+ raised.
  • 95% engineer retention — because we hire the top 1%.
  • You'll never just "take tickets" here. You'll own problems, ship fast, and grow with the founders we partner with.
  • Every project here feels like its own mini-startup. As an intern, you won't just learn how to code — you'll learn how founders think, how startups scale, and how engineers ship products that actually matter.
