Senior Infrastructure Engineer

Senior Infrastructure Engineer

Department: Engineering

Employment Type: Full Time

Location: Poland

Reporting To: Chief Technology Officer

Compensation: £80,000 - £90,000 / year

Hi 👋 I’m Bill, CTO ’re a high-growth HR tech company building and selling software that helps in-house recruitment teams attract, hire, and onboard the right talent. Today, we have a strong foundation in place, with a mature product, rapid growth, strong product–market fit, and happy customers.

As we grow, the complexity and expectations around our platform are increasing. We’re shipping more, supporting more customers, and reliability and performance can’t be reactive. To maintain trust and execution quality, we need deeper infrastructure ownership embedded in engineering. That’s where you come in.

We’re hiring a Senior Infrastructure Engineer to strengthen our platform reliability as we scale.

As the second member of our dedicated infrastructure team, you’ll operate as a senior individual contributor with meaningful autonomy. You’ll work across the full surface area of our environment and own problems end-to-end, partnering closely with our Lead Infrastructure Engineer, CTO, and senior developers to improve reliability across the organisation.

The fine print (but a bit more exciting):

• This is a remote-first role based in the UK or Poland
  , with occasional in-person team meetups. Our HQ is in Jersey (UK), and our ~90-person team is spread across the UK, US, and EU
• Our infrastructure team is intentionally small. You’ll be expected to operate independently as a subject matter expert. There isn’t a large platform team to lean on
• Our tech stack is pragmatic and maintainable rather than trend-driven. We run a monolithic Ruby on Rails application with a React frontend, deployed and managed via Cloud
  66. We use Git Hub and Git Hub Actions for CI, Terraform (Open Tofu) for infrastructure as code, and Datadog for monitoring and observability.
• Pinpoint isn’t for everyone. We’re still operating in startup mode. Things move quickly, priorities evolve, and we value people who take ownership rather than wait for instruction
• Our values actually matter here. We hire people who reflect them in how they work, collaborate, and make decisions

• Improve monitoring and alerting across infrastructure and application layers
• Diagnose and reduce production instability, including load spikes and database bottlenecks
• Strengthen our use of Datadog, particularly logging quality and alert signal-to-noise ratio
• Improve capacity planning through testing, monitoring, and forecasting
• Ensure new features ship with appropriate production metrics and reliability safeguards
• Implement and maintain best practices across infrastructure security, compliance, and vulnerability management
• Participate in on-call rotations, incident response, and post-incident analysis
• Maintain clear and up-to-date infrastructure documentation
• Improve our CI/CD pipeline and overall infrastructure performance

• Fewer surprise production incidents
• Faster diagnosis and recovery when issues occur
• Clear, actionable dashboards and alerts
• More predictable performance under load
• Increased engineering confidence when shipping new features

• 4+ years of hands‑on experience in infrastructure, Dev Ops, platform, or site reliability roles
• Experience maintaining the reliability and scalability of a production SaaS application
• Experience participating in on-call rotations and incident response
• Strong working knowledge of infrastructure as code (e.g. Terraform), testing practices, containerisation, and orchestration
• Experience with monitoring, metrics visualisation, and alerting platforms, ideally Datadog
• Strong problem‑solving ability and sound technical judgment in ambiguous environments
• Clear communicator who documents decisions and contributes to thoughtful post‑incident reviews
• Comfortable getting close to the codebase when needed
• Motivated to improve systems through automation and efficiency gains
• Curious and resourceful — AWS documentation doesn’t intimidate you

Huge plus if you have:

• Experience optimising MySQL, Postgre
  
  SQL, or Redis
• Deep familiarity with AWS
• Advanced Datadog experience, particularly…
