About this role
What You'll Do
- Ship features across the stack, back end and front end, in your first months to learn the product, the codebase and the teams
- Lead architectural and infrastructure initiatives end to end, from design to production: modernizing our mature PHP monolith, into microservices architecture , converting background processing to (TypeScript/Python) serverless on AWS, improving observability, and scaling our analytics on ClickHouse
- Make key technical decisions and set best practices: system design, data models, code quality and testing, and when to bring in new technologies
- Shape our agentic SDLC: how we plan, build, review and test with AI coding agents, and the guardrails around it
- Write and review critical code across the stack, front end included, and mentor engineers through design and code reviews
- Share ownership of production, including the on-call rotation
- Work closely with Product, team leads and engineers across R&D to turn business needs into sound technical plans
What We're Looking For
- 8+ years of hands-on software development, building and running web applications at scale

- Strong experience with at least one backend language (PHP, TypeScript/Node.js, Python, Java, C# or similar)
- Hands-on experience with an agentic SDLC: using AI coding agents (Claude Code, Codex, Cursor or similar) to plan, write, review and test code
- Experience evolving a large legacy codebase: refactoring, upgrades and incremental migrations while the product keeps shipping
- Deep experience with MySQL or another relational database, including data modeling and performance at scale
- Hands-on experience with AWS
- Hands-on experience with infrastructure as code (CloudFormation, Terraform, Pulumi or similar)
- Excellent communication skills and the ability to work across teams and departments
- Fluent English
A Plus If You Have
- Experience with PHP
- Experience with more than one backend ecosystem, such as PHP alongside TypeScript or Python

- Experience with analytical databases (ClickHouse or similar)
- Experience with NoSQL, search and in-memory stores (CouchDB, OpenSearch, Redis or similar)
- Experience with event-driven architecture and background processing at scale
- Experience building LLM-powered product features
- Experience working on complex B2B SaaS applications
