Job description

Role Overview

As a Senior Software Engineer at TP ICAP, you will play a key role in delivering business-critical software solutions supporting the internal broking division and its external client base.

You will operate within an Agile, cross-functional environment, contributing across the full software development lifecycle—from design through to implementation and post-release support. The role emphasises engineering excellence, continuous improvement, and scalable delivery, with a strong focus on automation, continuous integration, and deployment.

Role Responsibilities

• Collaborate with Architects and Principal Engineers to design and deliver solutions aligned with the broader IT strategy and architectural vision.
• Take ownership of the design, development, and delivery of key features, ensuring high-quality outcomes and timely completion.
• Partner closely with QA to ensure robust testing practices and the consistent delivery of high-quality, defect‑free software.
• Champion engineering best practices, including unit testing, code reviews, and maintainable design principles.
• Leverage AI-enabled development tools (e.g. Copilot, code assistants, automation tooling) to enhance productivity, code quality, and delivery velocity—within enterprise risk and control frameworks.
• Contribute to continuous improvement by evaluating and adopting appropriate technologies, tools, and methodologies.
• Design and deliver solutions that meet both functional and non-functional requirements (e.g. performance, scalability, resilience).
• Support and mentor junior team members, fostering a collaborative and high-performing team environment.
• Proactively communicate progress, risks, and dependencies, escalating impediments early to minimise delivery impact.
