Job description

We are a rapidly growing online travel agency with technology at the core of our success. In 2022, we facilitated millions of people on their dream holidays.

Handling a million visitors daily, our platform supports over 100 services, processing 8,000 requests per second, with a p95 search latency of 150ms. Our observability infrastructure captures and processes 1TB of logs daily and 350,000 metric samples per second.

We emphasize differentiation through open source contributions, including open sourcing internal tools, contributing to public repositories, and sponsoring conferences.

Responsibilities

As our first Site Reliability Engineer, you will help evolve SRE practices such as incident management, blameless postmortems, SLOs, and error budgets. Your role will involve building reliable, performant, auto-scalable, and highly available systems with support from the existing Platform Infrastructure team.

• Enhance SRE practices across teams.
• Improve reliability KPIs of the platform.
• Balance reliability with feature delivery using SLOs and error budgets.

Our engineering teams manage the entire lifecycle of services from initial development to high-load production operation. Your responsibility is to enable engineering teams to succeed in operations, not to run their services for them.

What you'll be working on

• Kick-start our SRE function by promoting reliability best practices and processes.
• Identify slow code paths in critical applications using tools like Java Flight Recorder or Go’s pprof.
• Develop or modify tools and applications with reliability and performance in mind.
• Ensure systems can handle ten times the current load by improving performance testing.
• Reduce mean time to discovery and recovery through enhanced observability and alerting.

We focus heavily on observability, continuously evolving our monitoring and alerting stack centered around the Mimir ecosystem (Prometheus, Grafana, Loki, Tempo). Our service mesh (Linkerd) provides uniform observability of all production services at 10-second intervals.

Performance and scalability are fundamental to our development process, achieved by combining core computer science principles with cutting-edge cloud technologies.

• Perform low-level debugging and troubleshooting.

What we'll give back to you

• Company pension contributions at 5%.
• Training budget to support your ongoing learning and development.
• Discounted holidays for you, your family, and friends.
• 25 days of annual leave plus 8 public holidays, increasing by 1 day every two years up to 30 days.
• Option to buy or sell annual leave.
• Cycle-to-work scheme, season ticket loans, and eye care vouchers.
