About The Role
What if your years of software engineering experience could directly shape how AI writes code for millions of developers? We're looking for Software Engineers in Istanbul to evaluate, rank, and refine AI-generated code — helping the next generation of coding assistants produce solutions that are correct, efficient, idiomatic, and production-ready.

Turkey's rapidly growing tech scene has produced exceptional engineering talent, and your deep understanding of software architecture, design patterns, and real-world engineering trade-offs is exactly what AI models need to get better. This isn't about writing boilerplate — it's about applying expert judgment to push the boundaries of what AI can do with code.

This is a fully remote, flexible contract role built for experienced developers who want meaningful, high-impact work on their own schedule.

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

What You'll Do

• Review and rank AI-generated code solutions across multiple programming languages and problem domains
• Evaluate code for correctness, efficiency, readability, maintainability, and adherence to best practices
• Identify bugs, anti-patterns, security issues, and performance bottlenecks in AI-generated outputs
• Write detailed, structured feedback explaining why one solution is better than another
• Refine and improve AI-generated code to meet production-level engineering standards
• Provide preference rankings that help AI models learn what "good code" actually looks like
• Work independently and asynchronously — fully on your own schedule

Who You Are

• Software engineer with 3+ years of professional development experience
• Proficient in one or more major programming languages (e.g., Python, JavaScript/TypeScript, Java, C++, Go, Rust)
• Strong grasp of data structures, algorithms, and computational complexity
• Deep understanding of software design principles, clean code practices, and engineering trade-offs
• Experienced with code review — you know how to assess quality and articulate why something works or doesn't
• Clear, concise written communicator who can explain technical decisions effectively in English
• Self-motivated and reliable when working independently without supervision

Nice to Have

• Experience across multiple languages, frameworks, or tech stacks
• Background in systems design, distributed systems, or backend architecture
• Familiarity with AI/ML concepts or experience using AI coding tools (Copilot, ChatGPT, etc.)
• Prior experience with code evaluation, technical mentoring, or open-source contribution
• Knowledge of security best practices and performance optimization
• Experience in competitive programming or technical interviewing

Why Join Us

• Work on cutting-edge AI projects alongside leading research labs
• Directly influence how AI coding assistants learn to write better software
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based work
• Leverage your hard-earned engineering expertise in a new, high-impact way
• Potential for ongoing work and contract extension as new projects launch
• Join a global community of top-tier engineers shaping the future of AI-assisted development

Role Overview:

We're looking for a hands-on R&D Mechanical Engineer to design and build a variable-angle wind tunnel for testing our VTOL delivery drones.

The wind tunnel will generate controlled wind speeds and directions while the aircraft remains mounted on a force-measurement test stand. The complete system will include motors, propellers, structural frames, airflow components, force sensors, actuators, and a large pivoting mechanism that allows the wind angle to be adjusted automatically.

This is a highly practical role involving CAD design, prototyping, fabrication, assembly, instrumentation, testing, and continuous improvement.

Key Responsibilities:

• Design the complete wind tunnel structure and airflow system
• Select and integrate motors, propellers, bearings, actuators, belts, gears, and structural components
• Develop a pivoting mechanism that can automatically change the wind tunnel angle
• Design test stands and fixtures for mounting VTOL aircraft
• Integrate force sensors and other measurement equipment into the test setup
• Create parts and assemblies in SolidWorks
• Produce components using 3D printing, CNC machining, sheet materials, and workshop fabrication
• Assemble, modify, and troubleshoot the physical system
• Conduct airflow, vibration, structural, and mechanical tests
• Work closely with flight-control and embedded-software engineers to integrate the wind tunnel into our verification pipeline
• Improve the system based on test results and experimental data

Qualifications:

• Degree in Mechanical Engineering, Aerospace Engineering, Mechatronics, or a related technical field
• Strong SolidWorks or equivalent CAD skills
• Experience designing and building mechanical systems or test equipment
• Familiarity with motors, propellers, bearings, belts, gears, actuators, and structural assemblies
• Experience with 3D printing, rapid prototyping, and workshop fabrication
• Comfortable using workshop tools such as drills, Dremels, saws, adhesives, and hand tools
• Good understanding of mechanical loads, vibration, tolerances, airflow, and structural design
• Experience with wind tunnels, test rigs, drones, robotics, or aerospace systems is a plus
• Strong problem-solving skills and a practical, hands-on approach

Why You'll Love Working Here

• Design and build a unique variable-angle wind tunnel from the ground up
• Work with an exceptionally talented team
• Work on cutting edge drone & AI technology
• Build real hardware and see it used in aircraft testing
• Good compensation
• Equity participation (Stock options)
