Senior Product Engineer

You'll take ownership of product features from problem to production. That means understanding the user and business need, exploring possible solutions, writing a clear technical specification, implementing the feature, releasing it, and learning from how people use it.

What you'll do

• Own your first feature end-to-end: understand the problem, shape the solution, write the technical specification, build and release it
• Work closely with Product and Design to turn customer and user insight into a focused product experience
• Use LLMs as a core part of your workflow while validating their output for correctness, maintainability, security, and performance
• Contribute across the stack, including frontend, backend, data, testing, and deployment where needed
• Own multiple product features from discovery through measurement and iteration
• Help improve engineering quality through better tests, observability, documentation, and development practices
• Contribute ideas that make it easier for the team to ship valuable software quickly and safely

What you'll need

• 6+ years of professional software engineering experience
• You've owned full feature development, including defining the solution rather than only building what someone else specified
• You can write a clear, technically grounded specification, and you know what makes one bad
• You have strong intuition for UX: you notice what confuses users, what creates friction, and what feels right
• You use AI and LLM tools as a core part of how you work across specifications, prototyping, and implementation
• You speak and write fluent English

Nice to have

• Experience building AI or LLM product features, including prompting, evaluation, or guardrails
• Experience working in a Startup, B2B SaaS or HR tech environment
