Senior Software & Data Engineer

Senior Software Engineer

Swarmia was founded to help engineering organizations ship exceptional software at a sustainable pace. As Swarmia engineers, we're not only building a platform for our customers but also ourselves.

We raised €10M in Series A funding in June 2025 and are growing fast. To help scale and expand the product, we're looking for several Senior Software Engineers who are both generalists and specialists: you know a little about everything and a lot about something.

About Swarmia

Swarmia is a SaaS product that gives engineering organizations the visibility they need to ship faster without compromising culture or quality. Our customers include some of the world's best software companies, such as Miro, Superhuman, and Bolt.

We're a team of experienced engineers who care deeply about our craft. We practice what we preach: we use Swarmia to build Swarmia, and we've figured out how to ship fast while keeping technical debt low and our work-life balance healthy.

About the Role and How We Work

You'll work across the full stack — from database schema design to UI components — shipping features that directly impact how engineering teams work. We're generalists who happen to specialize in different areas, and we expect everyone to be comfortable owning projects end-to-end.

Every Friday, we demo what we've built that week. People are genuinely proud to show their work. That's the culture we've created: solve real customer problems, ship continuously, and maintain a sustainable pace. No made-up deadlines, solo-projects, or needless bureaucracy.

We value initiative, ownership, transparency, feedback, and collaboration. When you see something broken, you fix it. When you spot a challenge on the horizon, you discuss it with the team and start solving it. We have enough process not to worry about the basics, but total freedom to influence what matters.

Examples of Things You'll Do

• Join other engineers, designers, and product management in defining the product direction and the features we're building

• Ideate and implement improvements in the product together with the team - we prefer collaborative problem-solving over working in silos

• Build integrations to HR systems so that large organizations can automatically sync their team structure to Swarmia

• Build support for contextual product documentation in the Swarmia app

• Build an LLM-based service or a good old machine learning model to automatically categorize pull requests or issues

• Extend access control so that new Swarmia users can easily delegate setup tasks to colleagues

• Delve into product analytics to identify bottlenecks in Swarmia adoption

• Build tooling that enables your colleagues to make data-driven decisions about product development

• Surface signals from the product to Sales and Customer Success colleagues to help them target white-glove service

• Build and maintain ETL pipelines that sync data from various systems into a BigQuery data warehouse

• Design data models and transformations that produce clean, reliable datasets for our analytics

• Optimize BigQuery workloads and schema to keep costs manageable as data volumes grow

• Implement data quality checks and monitoring to ensure data in our warehouse remains reliable

• Look near: Notice a drop-off in a critical user onboarding step? Just fix it!

• Look far: See the volume of product telemetry getting out of hand? Investigate the trend and work with the team to address it before it becomes a problem.

Why You Should Join

The Product: You'll get to work on a domain that's relevant and interesting to software engineers. Unlike many other tools in this space, Swarmia is not a tool for stack ranking individual engineers or just a dashboard for the leadership — instead, we serve useful insights and tools for the whole engineering organization. As an engineer, this means you deeply understand the problem space.

The Developer Experience: Since our product is about sensible software development, we take our own practices seriously. We're deliberate about how we work, but processes aren't heavier than they need to be. As one of our engineers described it after his first few weeks at Swarmia: "It feels like a bunch of adults came together and spent some serious time to figure out how to do this software thing well."

The People: You'll get very experienced colleagues with wide skillsets and different backgrounds. We pride ourselves in hiring and retaining smart, kind, and helpful people who are guaranteed to both teach you something and learn something from you.

The Communication: The psychological safety here is real — people voice their concerns without fear, and we're fast to try new things and scrap them if they don't work. We're deeply invested in the product and can have disagreements, but when we do, it's always in a professional and empathetic manner. Low hierarchy in practice. No blame culture.

The Transparency: We believe in total transparency across departments and leadership. You'll get full access to all business metrics, leadership team meeting notes, and board meeting memos. We all contribute to this by having our conversations on public Slack channels, openly sharing meeting notes, and collaborating on request for comments (RFC) docs before implementing any bigger changes.

The Balance: We're a startup with the maturity of a more established company. Things just work, but your initiative matters a lot. We maintain a great work-life balance, don't do any crunching, and keep up a sustainable pace without compromising quality.

Tech Stack

Strict-mode TypeScript everywhere with high test coverage. React frontend using Apollo and a design system that's tested with React Testing Library. Node backend with Apollo Server, slonik, and PostgreSQL. Infrastructure automated with Terraform on Google Cloud (GKE, PubSub) with automatic deployments to production after each change.

We don't expect you to know all these tools beforehand, though - we'd be happy to show you the ropes. We care more about how you think and how fast you learn.

Interview Process

We want to see how you work, not test your leetcode skills. The process includes:

1. Intro call with the recruiter to learn more about you and share more about Swarmia.

2. Hiring manager call — meeting with 1-2 engineering leads to deep dive into your experience.

3. Technical interview — no live-coding or home assignments. Conversation with 2 Swarmia engineers around the full spectrum of software development — frontend, backend, security, testing, DevOps, and software engineering practices — designed to explore your strengths and give you space to show what you know.

4. Leadership interview — a short discussion with our CEO and Head of Engineering to assess mutual culture fit.

We'll prep you for each round and provide feedback regardless of outcome. We aim to respond within 1-2 days. Our interviews are a two-way conversation - each stage is a chance for you to learn about us just as much as we learn about you.

Your First Few Months at Swarmia

Your dev environment sets up with a single script. You'll push your first change on day one. Over your first 90 days, you'll ship increasingly complex features — from simple updates to prominent features.

You'll get a designated onboarding buddy from your team, plus the whole team running training sessions on our culture, product, and technical architecture. You'll have regular 1:1s with your team lead to calibrate and give feedback.

Benefits

• 70-90k€ annual salary plus meaningful equity.

• Paid annual vacation with 10 extra days for new employees.

• Flexible remote/office balance — our whole Product & Engineering organization is based in Finland. We value meeting teammates in person, but you don't have to come to the Helsinki office every day.

• Great work-life balance — we're a startup, but we don't work at an unsustainable pace
