Senior Software Engineer

For one of our international client we are looking for Senior Software Engineer who work across infrastructure, platform tooling, CI/CD, and multiple languages including Java, Go, Python, and JavaScript but you don’t need to be an expert in all of them , but you’re genuinely comfortable picking up unfamiliar tools and technologies.

Location: office based in Warsaw, remote work on a daily basis, meetings at the office in Warsaw once every two weeks.

Daily tasks

• You’ll be building and maintaining the services we provide to engineering squads - things like CI/CD pipelines, Golden Paths and AI productivity tooling. Right now, our biggest focus is enabling and supporting AI adoption across the business
• We have a daily standup where the squad discusses yesterday, now and next. It’s often the only formal meeting of the day, so we take time to catch up socially and discuss challenges in depth
• We don’t have a product owner or tech lead, which gives us more autonomy over what we work on. It also means more responsibility - you’ll engage directly with stakeholders, prioritise based on impact, and deal with ambiguity. We use kanban so we can flexibly adapt. If a product squad is blocked, we want to be able to drop what we’re doing and help them immediately
• You’ll be on a rota for in-hours support, and it’s one of the most important things we do
• Engineers across the business come to us when they’re stuck - whether that’s a broken pipeline, a deployment issue, or something they’ve never seen before. It’s varied, often urgent, and requires strong debugging skills and patience. You need to genuinely enjoy helping people and take pride in doing it well
• The squad has a strong culture of pairing and mobbing. The breadth of what we work on and the collaboration with other squads means we learn a lot from each other, and working together is the most effective way to share that context
• Everyone in the squad is a senior engineer, and that shapes how we work. There’s no hierarchy beyond the EM - you’ll have real influence over what we build, how we build it, and where we focus. You’ll need to be comfortable forming your own view on what matters most and backing it up
