London office


Site Reliability Engineer (Remote Ok) helps homeowners find reliable tradespeople through the power of online reviews. We’re a market leader in the UK and are part of IAC, a well known New York based internet group (Vimeo,, Tinder, HomeAdvisor, etc.)

Our headquarters in Clerkenwell reflect our unique culture: we have an amazing office bar, guitars, a drum kit, a bike mechanic workstation, extensive library and a rotating food team who make lunch for everyone. It’s a fun place to be and that’s mainly because everyone in the team believes in the mission and is seriously good at what they do.

The role

In SRE, we’re fanatical about automation, monitoring and building resilient systems. We work hard to ensure reliability across the MyBuilder ecosystem, which often means talking about failure (what could go wrong?) and approaching every problem with fault tolerance in the forefront of our minds. We use a huge range of tools to help us with that, from Amazon Event Bridge for event-driven architecture, to Terraform with our Infrastructure as Code efforts, and GitHub Actions for all our automated builds, to name just a few.

Our ability to deliver quality software at velocity is important to us, so we spend a lot of time thinking about how best to support the MyBuilder Product teams. Perhaps that means writing scripts to automate away the pain of running a local development environment, or building infrastructure for a new API, or maybe configuring a DataDog dashboard for real-time performance monitoring. With such a broad scope of responsibility, no two days are the same in SRE at MyBuilder.

We want to work with people who are curious, honest, courageous and passionate - if that sounds like you and you want to work for an innovative, successful web business helping homeowners to find reliable tradespeople, then you may have found a new home.


  • Maintain our services by measuring and monitoring availability, latency and overall system health.
  • Maintain our multi-account AWS setup, comprising 50+ accounts, and the infrastructure therein.
  • Spend at least 50% of your time on development efforts that improve reliability, monitoring, performance and velocity.
  • Maintain our automated build, test and deployment pipelines.
  • Eliminate TOIL from our daily work through automation.
  • Practice sustainable incident response and blameless postmortems.
  • Not be afraid to contribute improvements to the Software Engineering team.

Our infrastructure is hosted entirely on the AWS platform using many of their services. Our current main stack comprises:

  • PHP 7.4/8.1
  • TypeScript/ReactJS
  • CloudFront (dynamic/static content delivery)
  • Lambda/API Gateway (handles 100% of web traffic)
  • SQS/EventBridge
  • RDS (PostgreSQL 13.5)
  • Fargate (Nginx reverse proxy)

We’re also in the process of migrating our background task system from EC2/Supervisor to Fargate.

Here are some of the tools we use to help us manage the stack:

  • Terraform Cloud
  • GitHub Actions
  • Docker
  • TrackJS
  • DataDog Logs, Metrics and APM

The right person

We are looking for people who care about good craftsmanship, who strive to improve themselves, their code and the workplace.

If you’re the kind of software engineer who likes to automate the job you do today for a more interesting job tomorrow, and if you’re able to quickly troubleshoot operational problems while also thinking of the bigger picture, then this SRE role might be for you.

Why you’ll enjoy working at MyBuilder

Engineering, Product and Design work together at MyBuilder, using agile processes in a highly collaborative environment with blurred lines between these disciplines. We have a large and complex product with more interesting challenges to solve than we have time to tackle.

We have daily check-ins for departments and project teams. We problem solve on paper, whiteboards and in Sketch. We prototype in the browser, deploy only when ready, and split test as much as possible with genuine users. We’re a small but growing team meaning you’ll have the opportunity to have a direct impact on a large scale product.

We offer all our employees the option to work remotely, in the office or hybrid. Whichever option you choose, we’ll give you a laptop with all the kit you need to work effectively. You’ll also get to spend quality time with your colleagues and meet your manager 1:1 on monthly office days.

We’ll also add:

  • 33 days holiday (including bank holidays) + 1 extra day for every year of service
  • 5% employer pension contribution
  • Comprehensive private medical insurance with AXA
  • Routine treatments health cash plan
  • Enhanced parental leave
