Backend Engineer PHP

You'll build the engine behind our Workforce Management platform, used daily by over 200,000 people across industries and regions. Together with Frontend, Product, and Infrastructure, you'll turn evolving business needs into backend systems that simply work - fast, stable, and reliable, even under pressure. Reliability doesn't just happen. We design for it. Like us, you care about clean data, resilient systems, and performance that never cracks. Not because anyone will see your code, but because they'll feel it when it fails, and at Dyflexis, that's not an option. We work in six-week build cycles, followed by two weeks to wrap up, improve, and prepare for what's next. Our tech leads code alongside you, so decisions stay grounded in real engineering. That means less red tape, more ownership, and a real say in how we scale. Your day will mix building and refining backend features that handle enterprise traffic, optimizing performance, partnering with DevOps on deployments and incident response, and mentoring engineers who are growing fast. Your core responsibilities are:

• Design features that handle enterprise traffic across regions
• Optimize critical paths for performance and reliability
• Follow patterns for code quality, testing, and readiness
• Partner with DevOps on deployments and monitoring
• Champion operational excellence in engineering decisions

Our current tech stack includes Core: PHP (Symfony), MySQL, Redis, Docker Infrastructure: Kubernetes, GitLab CI/CD, You'll earn up to €7,000 per month, work hybrid (2 days/week at our HQ), and join a bootstrapped company that's profitable and reinvesting aggressively in its products and people. No VC pressure, no corporate bloat, no endless approval chains. You'll work on systems serving renowned brands, leveraging a modern stack in a post-scrum environment that values focus. And you'll do it in a culture where we win together, have each other's backs when it counts, and celebrate success as a team. We also offer:

• Modern stack: PHP (Symfony), Docker, Kubernetes, GitLab, CI/CD
• Enterprise clients: every line of code affects real business operations
• Personal development budget
• 25 vacation days + your birthday off
• In-house chef, ARJ Boxing gym membership, solid pension plan
• 8% vacation pay, option to buy/sell vacation days

Do you have experience in Redis?, You have 5-7 years of experience building backend systems that thrived in production traffic. You know PHP intimately (modern practices, not the stuff that makes people wince) and understand the practical trade-offs between consistency, availability, and partition tolerance. You've optimized databases that were keeling over, debugged race conditions that only appeared under load, and made architectural decisions that didn't require a complete rewrite six months later. You think in systems, not tickets. When someone proposes a feature, you're already mapping failure modes and estimating the cost and maintenance effort. You care about reliability and performance and you're comfortable with ownership. You ship it, you own it, and you sleep soundly.

At Dyflexis we build HR tech for non-desk workers. Managers who lead teams in hotels, retail, and logistics trust us to help them win, every day. We're 100+ people across the globe with 45 engineers, launching new products to become the global standard. We are looking for a Senior Backend Developer to ship these products as we scale across Europe and enter the US. In short, this is what you can expect: * You'll work in focused 6-weeks cycles: a deliberate post-scrum method built for builders. You get time to do things properly: to think, craft and ship. * You'll earn up to €7,000 per month based on experience, work hybrid (2 days a week at our HQ), and join a bootstrapped company that's profitable and reinvesting heavily in its products and people. * No VC pressure, no corporate noise. Just autonomy, impact, and a culture where we win together and work as one team.
