Senior Cloud Platform EngineerJob Description
IG Group (LSEG: IGG) is a leading global fintech company, established in 1974 and headquartered in London. As an innovative member 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 eighteen 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, commodities and crypto.
IG is at a pivotal moment. We are moving with real pace and ambition -- rethinking how we serve clients, how we operate, and how we use technology to do both better. For people who want to be part of building something, rather than maintaining it, this is an unusually good time to join.
Your Team
You’ll be joining a small, close-knit Data platform engineering team of three to five engineers. We’re a team that takes quality seriously, looks out for each other, and gets things done without a lot of ceremony. Everyone brings something different across cloud infrastructure, data platform, and developer tooling and we rely on that range to solve problems well.
We work across time zones with colleagues in Bengaluru and Kraków, so clear communication and good async habits matter. You won’t be siloed into a narrow lane in a team of this size, everyone gets exposure to the breadth of what we do, and everyone’s opinion on how we do it counts.
Your role in the Team's Success
In a small team, a senior hire has an outsized impact - and this role is no different. Here’s what success looks like:
You raise the floor. Your experience with GCP and AWS means the team spends less time firefighting and more time building. You bring rigour to how we design and review infrastructure, and your instinct for security and reliability makes the whole platform better.
You unblock people. Data engineers, ML engineers, and Data teams depend on the platform to move fast. You’re the person who understands what they need, builds the right foundations, and makes sure the platform is something people trust rather than work around.
You make the IDP real. An IDP is only useful if it’s kept alive and relevant. You’ll be one of the people who makes sure it reflects reality - that services are catalogued, templates are current, and engineers across the business can actually find what they’re looking for.
You help the team get smarter. Whether it’s sharing a better way to use AI tooling, writing a clearer runbook, or spotting a pattern we’ve been missing - you make the people around you better at their jobs.
You own your outcomes. This isn’t a team with heavy process or close supervision. You’ll be trusted to take work end-to-end, flag when something’s wrong, and drive improvements without being asked twice.
You speak the business's language. The platform only matters if it delivers something the business can use. You'll spend real time with stakeholders across finance, compliance, BI and data science, understanding what they're trying to achieve, framing the trade-offs in language they can act on, and translating that back into platform decisions.
The best person in this role won’t just be technically strong - they’ll care about the team’s success as much as their own, and they’ll leave the platform in a better state than they found it.
What you'll do
Responsibilities.
Design and architect scalable cloud infrastructure, developing IaC solutions using Terraform and standardisation initiatives
Build, optimise, and maintain CI/CD pipelines for infrastructure deployment, supporting DevOps and DevSecOps best practices across the organisation
Operate and evolve GCP data platform services - BigQuery, Cloud Storage, Dataflow, Dataproc, Pub/Sub - in close collaboration with data and ML engineering teams
Support IAM, service account design, and security posture across the platform, enforcing least-privilege principles
Lead incident response and root cause analysis for platform issues, and drive improvements to reduce recurrence
Participate in an on-call rota as the platform's operational coverage matures.
Contribute to the development and maintenance of our IDP - adding catalog entries, improving scaffolder templates, and keeping TechDocs accurate
Work with data engineering and ML engineering teams to onboard their services and pipelines into the catalog, ensuring ownership and metadata are correctly represented
Use AI-assisted engineering tools - including Claude Code - as part of your daily workflow for infrastructure authoring, code review, and documentation
Share effective AI patterns and prompting approaches with the team, helping build a culture of thoughtful, safe AI-augmented engineering
What you'll need for this role
You’ll need solid experience in:
Cloud Infrastructure & Experience: 4+ years in cloud infrastructure engineering with hands-on experience designing and administering complex platforms in GCP including working knowledge of networking (VPC, VPCSC, Direct Connect) and IaaS/PaaS architectural patterns. Exp
Designing and operating Google Cloud Platform - BigQuery, Dataflow, Dataproc, Cloud Storage, Pub/Sub - at production scale
Infrastructure-as-Code using Terraform, with real hands-on experience of multi-environment configuration management across cloud providers
GitLab CI/CD - building and maintaining pipelines, runners, and merge request workflows
Cloud IAM and access control design, with a clear understanding of least-privilege and security best practices
Working collaboratively with data or ML engineering teams as a platform provider - not just building infrastructure, but making it usable
A consultative approach. You're comfortable working with non-technical stakeholders, interpreting requirements, challenging assumptions where needed, and influencing outcomes without retreating into jargon.
It would be a bonus if you have:
AWS exposure
Backstage experience - software catalog configuration, scaffolder templates, or plugin development
Familiarity with data platform concepts - medallion architecture, lakehouse patterns, or orchestration tools such as Airflow or dbt
Exposure managing Databricks
Practical experience with AI coding assistants (Claude Code, GitHub Copilot, Cursor, or similar) in a professional engineering context
Experience working in regulated financial services environments
