Fresha is the leading AI-powered operating system for the global beauty and wellness industry, giving businesses everything they need to run smarter, grow faster and build stronger client relationships.
In May 2026, Fresha secured an $80M growth investment from KKR at a valuation of $1B, officially reaching unicorn status and bringing total funding raised to $285M. Already profitable, Fresha is using this investment to accelerate global expansion and drive the next generation of AI and product innovation.

Our mission is simple: help beauty and wellness businesses grow by giving them the technology they need to attract clients, manage their operations and run their business in one place.
We’re continuing to scale rapidly across markets, teams and products, making this an exciting time to join us.
Role Overview:Team Lead, On-Call Automation and Reliability | The Bower, 207-211, Old St, Tower, London EC1V 9NR | Four days in office, Wednesdays remote
We're looking for a hands-on Team Lead for a new team. You'll report to the Head of Infrastructure. Your team owns what every engineer at Fresha uses when production breaks: alerting and paging, incident tooling, SLO and error budget tooling, the postmortem process, and the AI agents that do first-line triage.
Our product teams own their services and their on-call. Your team's job is to make that on-call quiet, fast and safe. A page should reach a human only when a human is needed. When it does, the context and a likely cause should already be there.
This is a software engineering team, not an operations desk. You build agents and automation that act on production, so you need to know when automation must stop and ask a person. You're also the line manager for everyone on the team.
We use AI as much as we can. Every engineer gets Claude/Codex/etc from day one, and we're building autonomous agents for SRE work. Your team takes that the furthest.
How We BuildProduction first: We have no pre-production environments. We test locally, validate in CI, ship behind feature flags, and hold a high quality bar. We ship with confidence because the platform makes it safe.
Unix philosophy: Each service does one thing well behind a clear interface, and complexity stays at the edges. We optimise for rate of change: an engineer with one year of experience should be able to make a change quickly.
Optional adoption, mandatory value: Teams choose their tools. Platform features win by being better, not by force. Only security and compliance are non-negotiable.
Automate first, document second: A check that blocks the merge beats a page nobody reads. We still write down context and decisions, for people and for AI.
Independent teams: Tribes own their code, deployments, on-call and roadmaps. The platform gives them what they need without waiting on anyone.
Technical leadership and delivery
Build and run the AI agents that triage alerts, collect context, suggest a cause, and run safe fixes inside clear guardrails.
Cut alert noise. Measure alert quality per team, and work with teams to fix or delete the alerts that don't help.
Own SLO and error budget tooling, and the reliability scorecard each team sees.
Own the incident process and tooling: roles, communication, postmortems, and follow-up on the actions.
Make detection and rollback fast. With no staging environment, the minutes after a deploy are where we catch problems.
Run game days and disaster recovery drills, and get the on-call rotas ready for seasonal peaks.
Run on-call for the services your team owns.
Write code, review it, and work through incidents alongside your team.
People leadership
Run your team: Know what each person is working on and where they're stuck, and step in quickly when someone is struggling.
Feedback and growth: Give feedback when it happens, help your engineers grow, and make the case for them when they're ready.
Hiring: Interview for your team and hold the bar on who joins.
Our stack: Kubernetes on AWS, Terraform, Kafka and Postgres. Services in Ruby, Elixir and TypeScript behind a federated GraphQL layer.
What We're Looking ForHands-on first: You write production code in at least one general-purpose language. If you've moved away from building and don't want to come back to it, this isn't the role for you.
Production experience: You've been on call for systems at scale, and you've led incidents as incident commander.
Automation you can trust: You've built automation that changes production, and you know how to make it safe: dry runs, limits, audit trails, and a human in the loop where it counts.
AI agents: You've put LLM-based tools or agents into real use, or you can show serious work toward it. You know where they help and where they fail.
Security: An agent with production access is a security risk. You design for least privilege and full audit from the start.
Cloud and observability: AWS, Kubernetes, and metrics, logs and traces at scale.
You've led a team: Formally, or as a senior engineer people already followed.
Product mindset: Engineers are your users. You track adoption and outcomes, run a roadmap, and say no to the wrong work.
Opinionated and clear: You write postmortems people read, and you can persuade a product team to change how they run their service.
At Fresha, we value passion and potential as much as specific skills. If you're enthusiastic and eager to learn, we encourage you to apply, even if you don't meet every listed requirement.
Your Opportunity at FreshaScale: Around 1 million bookings a day across 120 countries, and the payments that go with them, running on a platform we're breaking out of its monoliths while it serves traffic.
A new team: You shape its scope, its tools and its people from the start.
AI in production: Agents that do real on-call work, not demos.
