IG Group (LSE: IGG) is a leading global fintech company, established in 1974 and headquartered in London. As a constituent of the FTSE 100, IG Group provides dynamic online trading platforms and a robust educational ecosystem, empowering ambitious individuals worldwide in their pursuit of financial freedom. With operations spanning 18 countries across Europe, Africa, Asia Pacific, the Middle East, and North America, IG Group offers clients access to approximately 19,000 financial markets, including shares, forex, indices, and commodities.

IG Group is undergoing a significant transformation, led by CEO Breon Corcoran, appointed in early 2024. Our focus is on three areas: delivering quality products to better meet customer needs, embedding a high-performance culture across the organisation, and being more efficient and scalable through digitisation - all in service of growing our user base and revenue on a sustainable basis.

IG Group’s systems move billions of dollars every day - and our clients expect them to be fast, reliable, and transparent. As an Observability Engineer, you will own the platforms and practices that give IG's engineering teams deep, real-time insight into how those systems behave. This is a high, hands-on role at the centre of our reliability engineering agenda: building on Honeycomb and Open Telemetry, driving instrumentation across a globally distributed microservices estate, and partnering directly with development teams to turn telemetry data into better, faster software.

This role sits within the Observability team, part of IG's broader SRE and Platform Engineering function. The team is responsible for the tools, platforms, and standards that enable engineering teams across IG to understand and improve system behaviour  will report into the Senior Engineering Manager for SRE and Observability and work as an individual contributor, partnering closely with development squads, platform engineers, and incident response teams.

• Define platform standards, data models, and integration patterns for telemetry collection, storage, and querying across the estate.
• Instrumentation and telemetry – Drive Open Telemetry adoption across engineering teams, providing hands-on guidance and reusable instrumentation patterns for services built in Java, Python, and C++.
• Partner with development teams to improve telemetry coverage, ensuring meaningful traces, metrics, and logs are in place across critical services and user journeys.
• SLOs – Apply a strong understanding of SLOs, burn rates, and alert triggers to help service owners define meaningful reliability targets and translate them into actionable observability signals.
• Work closely with SRE teams to drive SLO adoption across the organisation, providing guidance and practical support to help engineering teams embed reliability targets into their day-to-day ways of working.
• Incident response – Join the support rota and incident response, using observability tooling to accelerate diagnosis and reduce mean time to resolution.
• Lead post-incident reviews that produce actionable improvements to both systems and observability coverage.
• Enablement and community – Mentor and upskill engineers across IG on observability principles and practices, raising the bar for how teams instrument, monitor, and debug their services.
• Develop training materials, runbooks, and best- practice guides that scale observability knowledge across the engineering organisation.
