Role description

Tired of just writing boilerplate? Ready to orchestrate, refine, and ship high-impact product features with modern agentic workflows?
If you are a builder who pairs solid engineering fundamentals with cutting - edge AI dev tools to multiply your impact, you’ll fit right in. You won’t just prompt and hope - you know how to critically review, debug, and architect resilient code that actually scales.

Here’s a breakdown of what you’ll do (not all of it, just the important stuff):

  • Drive product features end-to-end: Implement sleek, responsive UI improvements and connect them seamlessly with underlying APIs and backend services.
  • Supercharge your workflow: Leverage agentic coding assistants and AI workflows to accelerate delivery, prototype fast, and automate repetitive engineering tasks.
  • Be the human in the loop: Critically challenge, review, and refactor AI-generated code to maintain high architectural standards, security, and test coverage.
  • Collaborate in cross-functional squads: Partner closely with product designers, managers, and peer engineers in an agile cadence to turn ideas into production-ready software.
  • Level up code quality: Participate in code reviews, optimize client-side performance, and champion maintainable, clean-code practices across the codebase.

These are the essentials you’ll need to get an interview:

  • Solid frontend foundations: Proven professional experience building modern, responsive web applications using modern JavaScript/TypeScript and component-based frameworks (like React, Angular, or Vue).
  • Full-stack awareness: Comfortable navigating backend services, RESTful APIs, and basic data models to ship complete features independently.
  • Hands-on agentic development: Demonstrated experience actively utilizing AI dev tools (e.g., Cursor, Claude Code, GitHub Copilot, Windsurf) in your daily development lifecycle.
  • Strong code scrutiny & debugging: Exceptional ability to audit, debug, and refactor generated code for edge cases, performance bottlenecks, and architectural coherence.
  • Pragmatic problem solver: A curious, product-first mindset with strong communication skills and an eagerness to learn and collaborate with a Budapest-based team.

It would be great if you had these too, but we’ll support you if you don’t:

  • Experience with automated testing suites (unit, integration, and E2E like Jest, Playwright, or Cypress).
  • Familiarity with containerized development environments (Docker) and CI/CD deployment pipelines.
  • Hands-on experience building custom agentic workflows, prompt chaining, or LLM-driven tooling.
  • Exposure to cloud-native platforms (AWS, Azure) or distributed systems.

Role description

About The Role
What if the code you write could directly shape how the next generation of AI understands and generates software? We're looking for Software Engineers in Budapest to build, evaluate, and improve AI-generated code — helping train AI systems to think like real developers.

You'll write solutions, review AI outputs, and provide the expert-level feedback that makes AI coding assistants smarter, safer, and more reliable. This is hands-on engineering work at the frontier of AI development — not theoretical, not bureaucratic, and not boring.

This is a fully remote, flexible contract role. If you can write clean code and explain your reasoning, we want to hear from you.

  • Organization: Alignerr
  • Type: Hourly Contract
  • Location: Remote
  • Commitment: 10–40 hours/week

What You'll Do

  • Write, debug, and optimize code across a range of languages, frameworks, and problem domains
  • Review and evaluate AI-generated code for correctness, efficiency, readability, and best practices
  • Identify bugs, logic errors, security issues, and performance bottlenecks in AI outputs
  • Provide structured, detailed feedback explaining why code works — or doesn't
  • Design challenging coding prompts and edge-case scenarios to stress-test AI capabilities
  • Compare and rank multiple AI-generated solutions based on engineering quality
  • Work independently and asynchronously — fully on your own schedule

Who You Are

  • Proficient in one or more programming languages (Python, JavaScript, Java, C++, Go, TypeScript, or similar)
  • Solid understanding of data structures, algorithms, and software design principles
  • Able to read, write, and reason about code with clarity and precision
  • Strong problem-solving instincts and a systematic debugging approach
  • Clear written communicator — you can explain technical decisions in plain language
  • Self-motivated and reliable when working independently without supervision
  • Bachelor's degree in Computer Science, Software Engineering, or a related field — or equivalent practical experience

Nice to Have

  • Experience across multiple languages or tech stacks (full-stack, backend, systems, data engineering)
  • Familiarity with AI/ML concepts, LLMs, or prompt engineering
  • Background in code review, technical writing, or mentoring junior developers
  • Experience with cloud platforms, DevOps, or distributed systems
  • Competitive programming, open-source contributions, or side projects that demonstrate your craft
  • Advanced degree in Computer Science or related discipline

Why Join Us

  • Work on cutting-edge AI projects alongside leading research labs
  • Fully remote and flexible — set your own hours and work from anywhere
  • Freelance autonomy with intellectually stimulating, high-impact work
  • Directly influence how AI writes, understands, and reasons about code
  • Sharpen your own engineering skills by evaluating diverse problems daily
  • Potential for ongoing work and contract extension as new projects launch
