The job The Velocity team exists to eliminate friction. We treat our internal developers as our customers. You will: - Abstract Complexity: Build intuitive tooling that enables self-service allowing devs to focus on product logic. - Standardize Excellence: Bake best-practices, security, observability, and scalability into the core stack so they aren't afterthoughts. ## What You Will Do - Developer Experience: Build self-service tools that give product teams autonomy without sacrificing system stability. - Platform Engineering: Architect and evolve our core stack (AWS, EKS, Terraform). - Systems Resilience: Lead reliability initiatives, including business continuity planning and a sustainable on-call rotation. - High-Scale Privacy: Support the infrastructure for industry-leading privacy features, such as our TIME-recognized "Anonymous Mode." - Observability: Implement best-in-class monitoring (metrics, logs, tracing) to ensure issues are identified and mitigated before they impact the user. ## What You Bring - Experience: 6+ years in Infrastructure, DevEx, SRE, or DevOps roles supporting high-traffic, distributed environments. - Cloud Native Mastery: Deep expertise in AWS and Kubernetes (K8s) is essential. - Automation Mindset: Proficient in Infrastructure as Code (Terraform) - Technical Breadth: Ability to script and build tools in multiple languages (Python, Go, Scala, or Bash). - Communication: A "doc-first" mentality and the ability to collaborate across distributed product teams.

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.
