Help us scale across Europe

Up to €7K/month | Hybrid | PHP (Symfony)

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:

• No 2-weeks sprints, no ticket-chasing, no scrum theatre. We work in focused 6-weeks cycles: a deliberate post-scrum method built for builders. You get time and trust to do things properly: to think, craft, ship without the chaos.
• 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, have each other’s backs, and celebrate as a team.

What you’ll do

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 backend features that handle enterprise traffic patterns across multiple regions
• Optimize critical paths for performance and reliability (before users notice issues)
• Follow patterns for code quality, testing approaches, and production readiness
• Partner with the DevOps team on deployments, monitoring, and incident response
• Champion operational excellence in technical decisions – balance ambition with maintainability

The tech stack includes

Core: PHP (Symfony), MySQL, Redis, Docker

Infrastructure: Kubernetes, GitLab CI/CD

Scale: 200k+ active users, enterprise clients, multi-region architecture

Real problems: Query optimization, distributed data consistency

What we’re looking for

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, not just getting code merged. You're comfortable with ownership, you ship it, you own it, and you sleep soundly.

What you get

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.

Extra benefits

• Competitive salary up to 7k (based on experience)
• 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
