Must-have qualifications:
✅ 3 + years of hands-on Python engineering, including async patterns and automated testing.
✅ Proven experience with OpenAI (or similar) APIs and at least one agentic framework (Agent SDK, LangGraph, or equivalent).
✅ Deep knowledge of JSON Schema design, validation, and programmatic generation.
✅ Daily user of Postman (or similar) for API exploration and LLM prompt testing.
✅ A “solution first” mindset—comfortable leveraging third-party services instead of reinventing wheels.
✅ Growth mindset and humility: you delete code as eagerly as you write it.
✅ Clear written and spoken English and Polish; thrive in asynchronous, conversation-driven collaboration.

Nice-to-have skills:
✅ Exposure to real-estate domain concepts (IDX, MLS feeds, property data).
✅ Familiarity with Node.js, Angular, Java, MySQL, or AWS infrastructure.
✅ Contributions to open-source AI or agentic projects.
✅ Experience with evaluation tooling, RAG pipelines, or vector databases.

How we work:
✅ Solution-first: We measure success by delivered customer value, not lines of code.
✅ Conversation as IDE: We pair with LLMs continuously—Cursor chat, code suggestions, and Postman prompt boards are part of our daily flow.
✅ Adapt or die: What was state-of-the-art 30 days ago might be obsolete today. We pivot fast, celebrate deleted code, and keep egos low.
✅ One team: You will be the sole full-time AI engineer but will partner closely with product, design, and platform squads.

Why this role matters:
You will work for Placester – to build, host, and power high-performing real-estate websites for agents, brokers, and teams. We are doubling down on AI-driven, agentic workflows that generate complete real-estate websites—start to finish—in JSON format. As our first dedicated AI Engineer, you will turn cutting-edge LLM tools into production value for thousands of real-estate professionals.

⏰ Working hours:
You must overlap with the US-East team until at least 11 a.m. Eastern Time (5 p.m. Central European) on weekdays.

💵 Salary B2B: 15 000 -25 000 PLN net

Benefits:
✅ 25 days of paid leave in B2B service provision (plus all statutory holidays).
✅ Flexible working hours, possibility of remote or office-based work.
✅ Private health care (Luxmed).
✅ Subsidy for insurance (Warta).
✅ Access to online educational platforms (Udemy).
✅ MPCharity: a program where initiatives can be submitted for support.

What you’ll do in your first 6 months:
✅ Use OpenAI’s Agent SDK (Python) to orchestrate multi-agent workflows that output full website configurations compliant with our JSON Schema.
✅ Iterate rapidly via “vibe coding” in Cursor and chat-based development, treating conversation as your primary IDE.
✅ Prototype and refine prompts, tools, and memory strategies in Postman, then productionize them in our Python micro-services.
✅ Combine best-in-class third-party AI services—vector stores, RAG pipelines, evaluation frameworks—with just enough custom code to deliver customer value.
✅ Embrace ruthless refactoring: discard yesterday’s approach when a better one appears.

Responsibilities after ramp-up:
✅ Evolve our agentic architecture for scalability, security, and observability.
✅ Collaborate with teams using Node.js, Angular, Java, and MySQL to ship end-to-end site-generation features.
✅ Maintain and extend our authoritative JSON Schema–based Website Data Model; keep agents strictly schema-compliant.
✅ Track the fast-moving LLM ecosystem, proposing spikes and proofs-of-concept every sprint.
✅ Coach teammates on conversational development practices, Postman workflows, and AI safety.

Recruitment process:
STAGE 1: A 30–45-minute interview with a member of the HR team (you’ll receive information about the project, and we’ll ask questions in English to assess your current knowledge and experience).
STAGE 2: A 60–75-minute technical interview, during which we’ll verify your knowledge and skills relevant to the role.
STAGE 3: Approximately a 60-minute interview with the VP of Engineering.
