Job description

We’re a team of 500+ professionals who develop cutting-edge proxy and web data scraping solutions for thousands of the world’s best known businesses, including Fortune 500 companies.

What’s in store for you:

You’ll be solving complex challenges and maintaining our own infrastructure with 60PB+ monthly data traffic. Here are its scale and maturity in numbers:

- 6PB+ Ceph storage

- 60PB+ monthly data traffic through our systems

- 300k+ service requests/sec processed

- 500k+ Kafka messages/sec streamed

The team waiting for you:

Our Dashboard team owns the self-service platform every Oxylabs customer uses - the product that directly moves company revenue. You'll step in as the hands-on Tech Lead for one of our squads (PLAG or EP), working side by side with our Principal Engineer and setting the technical bar for ~14 engineers across two squads. We're mid-way through a major V3 architecture migration and scaling fast, so this is a timely moment to join: there's real architectural room here to make meaningful decisions, not just execute someone else's design.

In this role, you will:

Lead, mentor, and support one Dashboard squad while staying deeply hands-on in code - this is a genuine 50% IC role
Design and develop scalable, reliable, and maintainable systems across our Symfony 7 backend
Own the full development lifecycle for major features - from technical design and RFCs to deployment and production support
Drive architecture decisions in partnership with our Principal Engineer and help finish shipping the V3 migration
Raise engineering standards across code review, testing discipline, incident response, and observability
Contribute to cross-team architecture at the Dashboard product level, including Payments integration and outbox/Kafka patterns
Apply our leadership principles to guide your team and drive results

Your skills & experiences:

Deep PHP experience with Symfony strongly preferred (we're on Symfony 7.2 / PHP 8.3), plus practical MySQL 8 skills - query optimisation, indexing, and migrations at scale
Hands-on experience with Kafka, Redis, Docker, Kubernetes, and GitLab CI
Solid architecture chops - event-driven patterns (outbox), dual-database designs, and API design
Able to guide technical decisions, review designs and code, and mentor senior and mid-level engineers
A clear communicator who takes ownership, enjoys knowledge sharing, and gives constructive feedback

Nice to have:

Experience with payments/billing systems
DevOps/SRE inclinations, or prior work on multi-tenant self-service platforms.

Tech stack:

PHP 8.3, Symfony 7.2
MySQL 8, Redis, Kafka (outbox pattern)
Kubernetes, GitLab CI, Docker
Dual DB: Dashboard DB (users, products) + Payments DB (transactions, billing)
Frontend: React 19 / RTK Query

Salary & Benefits:

Gross salary: 6500 - 7300 EUR/month. Keep in mind that we are open to discuss a different salary based on your skills and competencies.
Growth & Learning: 40+ internal learning options, external conferences, mentorship, and year-round knowledge-sharing.
Health & Well-being: Private health insurance, psychotherapy, on-site well-being consultants, 24/7 gym access, and a wellness app.
Celebration & Community: Team events, an overseas workation, quarterly team-building budgets, and plenty of ways to mark milestones together.
Plus bonus vacation days, paid life-moment days off, barista coffee, and all the tools you need. See the full list of benefits here: https://career.oxylabs.io/blog/our-work-benefits/
