Copy of Junior Back-End Developer - Big Data (Relocation to Poland)

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 Istanbul 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

🚀 Who we are & What we believe?

We believe the internet is the great equalizer and enabler. It provides essentially unlimited access to knowledge, education, entertainment, services and commerce. And it’s an incredible tool to publish, create, share and communicate.

We think everyone deserves first-rate internet, and we have gone about creating an internet service that we ourselves want to use.

We believe in the power of curiosity, creativity and imagination. We use technology to realize our creations, to simplify and to enable. In addition, we add in hard work, sheer sweat and will power where that is not quite enough. If the idea is right, “that can’t be done”, or “that’s not how things are done” will not stop us.

Offering the best customer experience is dear to our hearts. Our industry is not very good at this, and we have lots of room to improve. We want to be the best and are looking for a leader that shares our passion.

If that’s you, we’d love to meet and get to know you. Let’s talk about how we can work together to make it happen!
