An overview of this role

As a Software Engineer on GitLab's Authorization team, you'll help build and maintain the system that decides what every user, token, and automated agent can access on GitLab.com, Self-Managed, and Dedicated. You'll work alongside experienced engineers who guide the larger design decisions, delivering well-scoped changes and growing into ownership of larger parts of the system.

Today, that work is Ruby on Rails. Roughly 400 policy classes and a catalog of about 1,900 permissions sit behind every application programming interface (API) request. You'll work on fine-grained token permissions, custom roles, and the GraphQL and representational state transfer (REST) APIs that enforce them. A single request can trigger hundreds of permission checks, so correctness and performance both matter.

You'll also contribute to moving the permission model to a new authorization stack that pairs the Rails monolith with a Rust policy engine. The engine represents access relationships and evaluates permission rules, and can run within the monolith's process or be reached through remote procedure calls using gRPC. You don't need prior Rust experience: several engineers on the team learned it for this work, and we'll support you doing the same.

Some examples of our projects:

  • Refactoring GitLab's policy layer so the same permission definitions can be evaluated by the monolith and the new authorization service
  • Extending fine-grained token permissions to more resources, with guidance from senior engineers on the design

What you'll do

  • Implement authorization changes in GitLab's Ruby on Rails monolith so permission checks allow intended access and deny unauthorized access.
  • Deliver well-scoped workstreams from feature-flagged rollout through verifying that the old and new systems produce the same results, with review and guidance from senior engineers.
  • Build and extend fine-grained permissions for tokens and roles so additional resources have permission coverage consistent with the established catalog.
  • Extend and fix authorization enforcement so GraphQL and the REST API enforce the intended permissions consistently.
  • Make incremental refactors to long-lived policy code without changing behavior for existing customers.
  • Investigate and fix reliability, performance, and security issues so affected permission checks return the expected results without regressions.
  • Work with the authentication, platform, and artificial intelligence (AI) teams to document interface contracts that keep permission checks consistent as authorization moves toward a shared service.
  • Contribute to design documents, merge requests, and code reviews so proposed changes have a documented rationale and review feedback is addressed asynchronously.

What you'll bring

  • Solid experience building and maintaining production Ruby on Rails applications, typically gained over 2 to 4 years or more.
  • Hands-on experience with authorization concepts, such as role-based access control or fine-grained permissions, from work or projects.
  • A security mindset: you treat a permission bug as a security bug and consider who a change could affect before choosing an implementation.
  • Experience making careful changes to existing codebases, including incremental refactors and feature-flagged rollouts that preserve existing behavior.
  • Familiarity with GraphQL or API authorization patterns.
  • Awareness of performance, including how repeated permission checks can add up on every request.
  • Strong written communication and the ability to work effectively when most decisions happen in a document or merge request rather than a meeting.
  • Helpful, but not required: hands-on PostgreSQL experience, or experience with Rust, gRPC or Protocol Buffers, Cedar or other policy languages, Zanzibar-style authorization systems, Go, or service-oriented architecture.

We welcome transferable experience from adjacent domains such as identity, policy engines, and platform security.

About the team

We work in a fully asynchronous organization, with most decisions made in documents or merge requests rather than meetings.

GitLab's mission is to enable everyone to contribute to and co-create the software that powers our world. Our values include collaboration, results, efficiency, diversity, inclusion and belonging, iteration, and transparency. We expect all GitLab team members to incorporate AI into their daily workflows to drive efficiency, innovation, and impact.

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.
