Job Title
Observability Engineer

Job Description

So, who are we?

IG is a FTSE 100 fintech operating across five continents, serving over 1.3m customers and handling billions of dollars in transactions - built on scale, trust, and proof. We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses.

The bar is high - bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next. Join us at IG - the future gets built here.

Your team:

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 at scale. You 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.

The Bengaluru team is deeply integrated into IG's global engineering community, with real ownership and scope to shape how observability is practised across the group.

Key responsibilities:

Platform ownership

• Build, maintain, and evolve IG's Honeycomb-based observability platform, ensuring it is reliable, scalable, and fit for a complex, globally distributed trading environment.

• Define platform standards, data models, and integration patterns for telemetry collection, storage, and querying across the estate.

Instrumentation and telemetry

• Drive OpenTelemetry 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.

Role requirements:

• 2-4 years of relevant experience in observability, SRE, or platform engineering roles.
• Proven hands-on experience with Honeycomb or a similar observability tool such as Grafana, including dataset design, query building, and using it as a primary tool for production debugging and reliability analysis.

• Strong practical experience implementing OpenTelemetry instrumentation in one or more of Java, Python, or C++, including custom collectors, exporters, and sampling strategies.

• Experience working in complex, distributed microservices environments with high transaction volumes or strict reliability requirements.

• Strong communication and collaboration skills - able to work effectively with development teams and influence engineering practice without direct authority.

• Practical experience with Terraform for managing observability infrastructure as code, including provisioning and maintaining platform components in a cloud environment.

• Ability and willingness to cover UK working hours to support collaboration with IG's London-based engineering teams.
