An overview of this role

We are looking for a Backend Engineer to join our Change Record team within GitLab’s Source Code stage. As AI agents increasingly write code alongside people, every change needs a clear, trustworthy record of what changed, why, and who or what made it. You’ll build that record into GitLab’s source code experience, for humans and agents alike. This is a backend-focused role for an engineer with full-stack experience who enjoys balancing work on existing systems with new product development.

That work happens in one of GitLab’s oldest and most complex product areas, where you’ll use Ruby on Rails to improve a critical system serving GitLab.com, self-managed instances, and GitLab Dedicated. Source Code provides the interface layer, through Gitaly, to the Git repositories behind a large share of GitLab traffic, so you’ll help keep it reliable through performance tuning, caching, rate limiting, observability, and resiliency, collaborating with product, design, security, Gitaly, Code Review, and Source Code Experience teams. Supporting production systems and improving established experiences are central to the role, especially while you’re onboarding, and over time you’ll also help build experiences for developers working with agents.

You'll work remotely from the United Kingdom or Poland.

What you’ll do

  • Develop secure, well-tested, performant features and improvements using Ruby on Rails and GraphQL, among other technologies.
  • Work through complex requirements and legacy constraints to deliver clear solutions while protecting the reliability of this critical system.
  • Design and maintain backend services, APIs, data models, and business logic that support intuitive source code workflows.
  • Collaborate across functions and teams, both asynchronously and synchronously, and involve domain experts when their input will improve the outcome.
  • Use AI agents for well-scoped work when they can speed up delivery without sacrificing quality, and critically review their output.
  • Write maintainable code that follows GitLab's standards and contribute to constructive code reviews.
  • Help strengthen reliability by monitoring production health metrics, participating in Tier 2 on-call, troubleshooting incidents, contributing to root cause analysis, and improving observability and resiliency.
  • Share knowledge through code review, technical documentation, and everyday collaboration while learning from others.

What you’ll bring

  • Professional experience building backend web applications, services, or application programming interfaces, with experience using Ruby and GraphQL.
  • An understanding of relational databases, structured query language, data modeling, caching, background processing, and backend performance practices.
  • Experience with full-stack development to build and maintain user-facing workflows and their underlying systems.
  • Experience writing backend unit and integration tests, with familiarity with the testing pyramid, Git, and collaborative code review processes.
  • Clear written and spoken English communication skills, including sharing useful status updates in a remote, asynchronous environment.
  • The ability to manage assigned priorities, work through ambiguity, take ownership of your work, and seek guidance when needed.
  • Experience using AI coding agents to speed up software development while critically reviewing their output.
  • Bonus: you’ve built agents or agent-based workflows that run in production, not just prototypes.

About the team

The functional team works across Europe and North America, supporting both synchronous and asynchronous collaboration. It includes four engineers, comprising both backend and frontend engineers. We work closely with other Source Code teams, Agentic Preview, Repository Services, and Hardening, as well as other teams in the company such as the Gitaly team, and the AI Governance team.

 

The base salary range for this role’s listed level is currently for residents of the EU, applicable in the specified country or countries only. Sales roles are also eligible for incentive pay targeted at up to 100% of the offered base salary. Grade level and salary ranges are determined through interviews and a review of education, experience, knowledge, skills, abilities of the applicant, equity with other team members, alignment with market data, and geographic location and having regard to any applicable collective agreements. The base salary range does not include bonuses, equity, or benefits.

Poland base salary range: 248,000zł - 372,000zł

Senior Backend Engineer

Flo HealthАвтоподнятие
Зарплата не указанаЛитваВильнюсГибрид

500M+ downloads. 80M+ monthly users. A decade of building – and we’re still accelerating.

Flo is the world’s #1 health & fitness app worldwide on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 – and we’re not slowing down.

With 7M paid subscribers and the highest-rated experience in the App Store’s health category, we’ve spent 10 years earning trust at scale. Now, we’re building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.

The job

Build systems that power the #1 Health App for Women

We’re not a startup guessing what might work anymore, we’re operating at serious scale. Flo is used by 1 in 4 women aged 18–44 in the US. And we just hit our biggest month ever with 8.6M installs and a 2.8M MAU jump. The engineering behind that? Complex, distributed, secure and yours to help shape.

At Flo, backend engineering is core product work.

We build:

  • Data-driven health insights that genuinely change lives
  • Distributed systems that stay fast, available and scalable under massive real-time demand
  • Privacy-first features like Anonymous Mode -  recognised in TIME’s Best Inventions
  • Tooling and platforms that help Flo’s teams move faster, with fewer bottlenecks

We’re tech-agnostic when hiring for backend. If you’ve built and run distributed systems and want to work in Scala (or already do), great. We’ll support your ramp-up. What matters most: you can solve problems, own outcomes, and keep learning.

Your Experience

You’ll thrive here if you:

  • Have 7+ years’ experience building distributed backend systems
  • Know what it takes to make systems fast, reliable and secure and when to prioritise each
  • Are fluent in Java, Scala, Python or similar (and curious enough to learn Scala with us)
  • Get DevOps, databases (SQL and NoSQL) and love designing APIs that just work
  • Have a strong handle on writing clean, documented, version-controlled code
  • Take ownership, show initiative and don’t wait to be told
  • Are product-minded and always thinking about the end-user impact

Bonus if you’ve worked with:

  • Stream processing
  • Public cloud infrastructure (AWS, GCP etc.)

What’s in it for you?

You’ll join a senior engineering team that moves fast, thinks big and builds tech used by millions daily. You’ll work on meaningful problems with real impact - in health, privacy and scale. This isn’t just code for the sake of code. This is building the future of personalised health.

#LI-Hybrid #LI-LM12

Salary Range - gross per month (ranges may vary based on skills and experience)
€6.500—€10.000 EUR

How we work

We’re a mission-led, product-driven team. We move fast, stay focused and take ownership – from brief to build to impact. Debate is encouraged. Decisions are shared. We care about craft, ship with purpose, and always raise the bar.

You’ll be working with people who take their work seriously, not themselves. It takes commitment, resilience, and the drive to keep going when things get tough. Because better health outcomes are worth it. 

What you'll get

We support impact with meaningful reward. Here’s what that looks like:

  • Competitive salary and annual reviews
  • Opportunity to participate in Flo’s performance incentive scheme
  • Paid holiday, sick leave, and female health leave
  • Enhanced parental leave and pay for maternity, paternity, same-sex and adoptive parents
  • Accelerated professional growth through world-changing work and learning support
  • In-person collaboration and work in a hybrid model, with 3 days per week spent in the office
  • 5-week fully paid sabbatical at 5-year Floversary
  • Flo Premium for friends & family, plus more health, pension and wellbeing perks

Diversity, equity and inclusion

Our strength is in our differences. At Flo, hiring is based on merit, skill and what you bring to the role – nothing else. We’re proud to be an equal opportunity employer, and we welcome applicants from all backgrounds, communities and identities. Read our privacy notice for job applicants.
