Company: CompanyHouse
CompanyHouse is the leading German business information platform. We crawl, parse, and structure data from official German trade registers, annual reports, and public filings - serving company profiles, financial data, and shareholder reports to thousands of paying customers across 4M+ German companies.
We are a small, senior-heavy engineering team (5 developers + PO) based in Poland, working fully remotely for a Swiss-German product company. We ship to production multiple times per day and AI tools are a core part of how we build.
About the role
We're looking for a mid-level PHP developer who uses AI coding tools as a natural part of their workflow - not as an afterthought. You'll work on a mature, complex PHP/PostgreSQL codebase with real production impact: data pipelines, crawlers, parsers, and financial report processing.
This is not a greenfield project where you prompt your way to an MVP. You'll be working inside a large existing system with real data, real customers, and real complexity. AI tools help you move faster, understand code better, and write more reliable solutions - but you need to understand what you're building and why.
What we expect from AI usage
This is central to the role. We don't just allow AI tools - we require and measure them:
- You'll use JetBrains AI Assistant with MCP connections to Jira, Confluence, and PostgreSQL
- You'll log AI usage on every Jira ticket (tool used, contribution %, quality)
- You'll use project-level prompts (.ai/prompts) for testing and code review
- You'll join monthly AI knowledge-sharing sessions
We want someone who uses AI strategically - to investigate bugs faster, write better tests, understand unfamiliar code, and accelerate their own cycle. Not someone who pastes from ChatGPT without understanding the output.
Tech stack
Backend: PHP 8.x (Yii2), PostgreSQL (100M+ rows), ElasticSearch NLP: Python microservices (Flask, gunicorn) Automation: Selenium WebDriver Infra: Hetzner bare metal + cloud, Jenkins CI/CD, Nginx Monitoring: New Relic, Graylog, PgBadger Tools: Jira, Confluence, Bitbucket, Tempo AI: JetBrains AI Assistant, Claude Code, MCP servers, project prompts
How we work
Kanban - no sprints, continuous delivery. ~70 production deployments per quarter. PR-based code reviews with 24h turnaround. Weekly 1:1 with PO for planning. OKR-based performance tracking. AI usage tracked per ticket.
Salary
15,000 - 22,000 PLN net/month (B2B). Higher end for candidates who demonstrate strong AI-augmented coding during the recruitment task.
Work model
Fully remote. Team distributed across Poland. Flexible hours within CET timezone (core overlap 10:00-15:00).
Perks
- Fully remote + flexible hours
- Training budget (AI tools, conferences, courses)
- AI tooling provided (JetBrains license, AI Assistant, Claude credits)
- Small team - your work has direct product impact
- No corporate overhead - direct access to PO and decisions
