Staff Software Engineer

Join Our Team as an Staff Backend Engineer!

Join our cross-functional team in Real Estate (Otomoto in Poland and brands in Ukraine, Romania and Portugal).

Are you someone who is craving scalable problems and dealing with optimizations?

You'll work with a creative, critical, and well-organized team from the comfort of your house, but as close as we have ever been!

You will play a key role in enabling our organisation to scale efficiently.

The Staff role here means being an independent technical expert - making autonomous decisions and influencing how entire engineering teams work, not just your own code. The current priority is migrating our PHP monolith to microservices in Go - you design new domains from scratch, based on business understanding. You decide what gets extracted next and why.

We're also building our own AI dev harness - focusing on context engineering, evals, and agent orchestration, on top of a solid microservices foundation written in Go.

Who are we looking for:

• You can use agentic workflows (Claude Code, Cursor Agent, or equivalent) as your default, not as a novelty.
• You practice context engineering, not just prompt engineering; you design the full information architecture an AI agent needs to succeed: repo structure, CLAUDE.md / AGENTS.md configs, relevant code context, memory, and tool access.
• You understand model routing trade-offs (e.g., when to use Haiku vs. Sonnet vs. Opus) and multi-agent orchestration.
• Strong ownership instinct: AI output is a first draft, not a deliverable; you validate, refactor, and take full accountability.
• You have strong Coding and Computer Science Fundamentals. Roughly ⅔ of your time will be hands-on technical work: designing solutions, steering and reviewing AI-generated code, developing new ideas, and reviewing others' contributions. The rest goes to cross-team influence, mentoring, and strategic alignment.
• Strong background experience in Golang, Java/Kotlin (preferred technologies), and able to work with PHP. Flexible and capable of adjusting to changing project requirements, roles, and backend technologies as needed.
• Scalable Systems Expertise. Experience with large-scale web applications, an economic-thinking mindset, and being able to design well-bounded future-proof domain systems, aligned with the business objectives.
• Deep expertise in scalable distributed systems, CI/CD, RESTful and GraphQL APIs, AWS, and relational + NoSQL databases.
• Big-picture thinker: aligns technical decisions with business strategy, influences without authority.
• Clear communicator in English across engineering, product, and leadership audiences.
• Self-starter who identifies what needs doing and takes initiative without waiting to be asked.
• Skilled Technical Leader and Mentor: Guide and support engineers by setting a strong example. As a Staff Engineer, you are a role model, leading by example and through your expertise
