Platform Engineer - Capital Market's - Sheffield (Hybrid)

Caspian One is partnering with a leading capital markets organisation on a large scale platform engineering programme and is looking to build out a number of experienced engineers to support delivery of an internal development platform.

This is a hand -on, coding first role ideal for engineers who enjoy designing and building distributed systems at scale, rather than purely working in DevOps or infrastructure-focused positions.

What you'll be doing

• Designing and building scalable Back End systems and APIs
• Writing production-grade code daily (Java, Node.js or Python)
• Contributing to a modern internal platform that supports a large engineering user base
• Solving complex technical problems through robust system design and architecture
• Working across hybrid environments (on-prem + cloud)
• Collaborating with SRE, platform and DevOps teams to improve reliability, performance and developer experience

What we're looking for

• Strong hands-on coding experience in Java, Node.js or Python
• Proven experience building APIs and distributed systems at scale
• Solid understanding of core Internet fundamentals (HTTP, DNS, TLS, networking)
• Experience delivering end-to-end solutions from design through to production
• A coding-first mindset this is not a tooling or ops-only role

Nice to have

• Exposure to platform engineering, SRE or DevOps environments
• Experience with containers (Docker, Kubernetes) and cloud (AWS or GCP)
• Familiarity with observability tooling (eg Grafana, OpenTelemetry)
• Understanding of service mesh, API gateways or load balancing

Why join

• Work on high-scale, high-impact systems used by thousands of engineers
• Be part of a modern engineering transformation
• Join a collaborative, engineering-led culture with strong technical standards
• Opportunity to influence platform direction and best practices
