Software Engineer – Infrastructure / Observability Focus (Inside IR35, up to £750/day) Are you a software engineer who enjoys solving infrastructure problems - someone who sits comfortably between development and platform engineering? Join a small, high-performing engineering team on a project at a top-tier quant fund, helping to build out observability capabilities. This is not an SRE or sysadmin role – it would suit a software engineer who cares about clean, testable code and good software practices, but prefers working in the infra/tooling space. What you’ll be doing: Writing Prometheus exporters and integrations for infrastructure systems Building out dashboards and monitoring pipelines in Grafana and Prometheus Developing infrastructure-as-code tooling (Terraform, Ansible) Designing well-structured, testable software that improves system visibility What they’re looking for: Strong software engineering skills (Go or Python preferred) Experience working in or alongside platform engineering teams Familiarity with modern observability tools (Grafana, Prometheus, etc.) Comfort working across both code and infrastructure – but this is not a pure ops/SRE role If you've worked in finance that would be great but not mandatory The role offers an initial 6-month initial contract, Inside IR35, up to £750/day but may be some flexibility. The role requires two days on site in the firm's state-of-the-art offices in London.
