Insight Global are seeking a Senior Lead Platform Engineer to join the Platform Engineering function of a large, global financial services organisation. This is a senior, hands‑on technical leadership role operating at the intersection of application engineering and infrastructure, supporting a complex, high‑scale engineering estate.
This position requires 3 days onsite in Bromley, UK for a 12‑month contract Inside IR35, converting to a full-time hire upon completion of the contract.
Role Overview
The Senior Lead Platform Engineer will act as a senior technical escalation point across multiple global delivery teams, supporting application, platform, and infrastructure layers. The role focuses on platform reliability, observability, resilience, CI/CD, and cloud adoption, while operating in a high‑pressure, enterprise environment.
This role is not suited to candidates who are solely Java developers or solely DevOps engineers — strong capability across both disciplines is required.
Key Responsibilities
* Design and build enterprise‑grade platform and application components aligned to established architecture standards.
* Act as a senior technical escalation point for production and non‑production issues across application, platform, and infrastructure layers.
* Lead incident triage, root cause analysis, and drive long‑term resilience and reliability improvements.
* Design and implement platform‑level monitoring, observability, and performance solutions at scale.
* Own and drive CI/CD pipelines, deployment processes, and automation.
* Bridge development and infrastructure teams to ensure smooth delivery and operational handoffs.
* Lead cloud platform adoption, defining runtime standards, platform services, and best practices.
* Provide hands‑on technical leadership and mentoring to engineers across delivery teams.
Must‑Have Requirements Include:
* Strong experience designing and supporting enterprise‑scale platforms and applications in complex environments.
* Hands‑on expertise with Java / J2EE, Spring, Spring Boot, and integration technologies such as Mule and Kafka.
* Experience with SQL and PL/SQL (Oracle) and large‑scale API and microservices architectures (XML/JSON).
* Strong experience with container platforms such as OpenShift and/or Kubernetes.
* Proven experience supporting on‑prem, containerised, and hybrid cloud environments.
* Hands‑on experience with CI/CD pipelines and DevOps tooling.
* Experience administering and using observability tools such as Splunk, Dynatrace, Grafana, or Prometheus.
* Strong communication skills with the ability to support and influence large developer populations in high‑pressure situations.
Plusses Include:
* Experience in a technical leadership or delivery‑focused role.
* Advanced CI/CD tooling and infrastructure automation experience.
* Strong Unix/Linux experience, including shell scripting.
* Advanced networking knowledge (DNS, load balancing, firewalls, proxies).
* Experience working in highly regulated, global enterprise environments.
