Product Engineer

About Us

Meet one of Turkey's best startups. Kolay’s journey started in 2015begankey’s first HR SaaS company, with the desire to simplify and ease the work of human resources, streamlining organisations all over the world, and let their employees fulfil their world and take me into more meaningful work.

Today, Kolay is a cloud-based HR management platform that streamlines processes for expenses, leaves, overtime, shifts, payroll, and more, trusted by more than 2.500 companies and 300.000 employees worldwide.

And we’re just getting started. We believe the next leap in HR isn’t just better software, it’s AI that actually works inside a customer’s real processes. That’s where you come in.

About the Role

We’re hiring Product Engineers: a new kind of role for a new way of building. The hardest part of product development is no longer writing code; it’s identifying the right problem and making the right decisions. So we’ve reshaped how we build around that reality.

As a Product Engineer, you own a feature end-to-end: from idea, through design, code, and testing, to production. You won’t wait in a queue behind three other teams. You’ll use AI as a first-class tool at every stage (to generate, iterate, and accelerate) while you stay firmly in the driver’s seat on judgment, context, and quality. AI generates; you decide. What ship is yours.

This is for engineers who want range and ownership, who are genuinely excited about AI-native development, and who care more about the outcome than the ticket count.

What You’ll Do

• Own features end-to-end: take an idea from problem definition to live production, across front-end, back-end, and everything in between.
• Build with AI as a daily partner: use AI tooling to scope, design, generate code, and write tests; direct it with strong context and review everything it produces.
• Ground your work in real customer signal: build what customers actually need, validated against real feedback, not just personal conviction.
• Hold the quality bar: write meaningful tests, care about performance and security, and make sure correctness is never optional in a payroll and HR domain.
• Respect the design system: ship interfaces that are consistent with our component library and design standards.
• Collaborate across functions: work with product, design, and customer-facing teams to turn problems into shipped value.

What We’re Looking For

Must-have

• Solid full-stack ability, comfortable reasoning about both back-end and front-end code (our stack includes PHP/Laravel, Angular, Node.js/TypeScript, and Python).
• A track record of shipping, you’ve taken things to production and owned the result.
• Fluency (or strong eagerness) with AI coding tools: you already use them, or you’re hungry to make them a core part of how you work.
• Strong product judgment, you ask “should we build this?” before “how do I build this?”
• Ability to work independently in a fast-moving environment and take full responsibility for what you ship.
• Comfort reading and validating code you didn’t write line-by-line, including AI-generated code.

Nice-to-have

• Experience with relational databases, RESTful APIs, and cloud platforms (AWS) and containerization (Docker).
• A feel for HR, payroll, or other compliance-heavy domains.
• A public portfolio, open-source contributions, or side projects that show how you think.
