Senior Infrastructure Engineer

Vilnius

We’re very proud of our achievements:

In July 2024, we secured a $200M investment led by General Atlantic to help revolutionise women’s health, and became the first purely digital consumer women’s health app to achieve unicorn status! 🦄

We’ve had 380M+ downloads, have over 70M monthly users, are #1 by installs in the iOS Health category, hit 4.9 stars on the App Store (3M+ reviews), are backed by 9 VCs, had a 40% revenue increase last year, and topped a valuation of $1B.

We’re a growing, ambitious HealthTech business building the essential digital health partner of tomorrow to empower women, girls, and people who menstruate with the knowledge and support they need to stay well and live better.

Our cycle, ovulation and pregnancy tracking, educational content and anonymised community platform have been trusted for years by millions to help them feel more in control of their health every day.

Now, we’re harnessing the power of data analytics and AI to build a smarter future, one where we all know our bodies better, with an aim to become the essential health partner to women worldwide.

The Job

We’re not chasing product–market fit. We’ve found it. Flo is used by 1 in 4 women aged 18-44 in the US. Last month alone, 8.6M new installs and a 2.8M user jump. That kind of scale doesn’t just happen. It’s engineered. That’s where you come in.

We’re hiring a Senior Infrastructure Engineer to join Velocity, our internal platform team. Velocity exists to make engineering at Flo faster, safer, and more innovative. Your mission? Build the systems that empower our devs to ship like pros without breaking things.

What Velocity does:

  • Automates everything worth automating
  • Hides complexity behind clean, intuitive tooling
  • Bakes in security and standards so teams don’t have to think twice

What you’ll help build:

  • Distributed systems that handle millions of real-time health interactions
  • Privacy-first features like Anonymous Mode (named in TIME’s Best Inventions)
  • Self-service tools that give teams speed without chaos
  • A stack that scales - fast, available, and secure, always

You’ll thrive here if you:

  • Have 6+ years in Infra, SRE, DevOps or similar roles in high-scale environments
  • Know AWS, Kubernetes, and CI/CD like the back of your hand
  • Understand observability (metrics, logs, tracing) and why it matters
  • Can debug at the Linux kernel level and aren’t scared of a flame graph
  • Have experience with multiple languages (Python, Bash, Scala, Go, etc.)
  • Communicate, document well, and collaborate like a pro

Bonus points if you’ve: 

  • Hardened infra with security best practices
  • Shipped at scale in a consumer tech environment

What’s in it for you:

  • Own our core infrastructure stack (Terraform, Kubernetes, Sentry, EKS, Ansible)
  • Shape and scale infra-as-code with autonomy
  • Equip engineers with best-in-class observability so issues get fixed before they’re felt
  • Play a lead role in reliability and resilience through on-call and business continuity planning
  • Take security seriously - and help raise the bar across the company

You're not just keeping the lights on. You're building the grid. If that sounds like your kind of challenge, let's talk.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
