PHP Developer (AI-First Workflow)

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
