About the Role

As the Principal Engineer in our Transfers Tribe, you will be the technical authority across the Transfers domain, shaping the architecture, technical direction, and long-term health of systems. You will focus on solving the hardest technical and architectural problems at scale, reducing systemic risk, and enabling teams to deliver faster without compromising stability, security, or regulatory compliance. You will work closely with Engineering Managers, Product Managers, Architecture, and Platform teams within an end-to-end, product-led delivery model.

Key Responsibilities

Collaboration & Influence

• Lead through influence: Align stakeholders, run design reviews, drive decisions, own technical governance and unblock delivery teams.
• Work closely with Product, Operations, Architecture, and Platform teams to ensure solutions are fit for live service.
• Support regulatory, audit, and operational discussions by clearly articulating technical design choices and risks.

Technical Strategy & Architecture

• Set and evolve the technical direction for the Transfers domain, ensuring architectural integrity, scalability, and resilience.
• Own and maintain architectural principles, guardrails, and standards, balancing short-term delivery with long-term sustainability.
• Lead early technical discovery for initiatives, shaping solution options, trade-offs, and technical risk assessments.
• Identify and proactively reduce system-level and cross-team technical risks, including performance, operability, and data integrity.

Engineering & Problem Solving

• Solve complex technical problems across event-driven flows, integrations, orchestration, and data consistency.
• Drive improvements in testability, observability, deployment safety, and recovery across Transfers systems.

Technical Leadership & Enablement

• Act as a technical mentor and coach to senior engineers, raising the technical bar across tribes
• Partner with Engineering Managers to enable sustainable, predictable delivery.
• Provide clear technical direction through shared patterns, guidance, and architectural decisions.

Skills & Experience

Essential

• At least 2+ years in a Principal Engineering or Solution Architect role or similar
• Proven ability to set technical direction across multiple teams without line management responsibility.
• Strong Java software engineering background with the ability to engage on architecture decisions. We use Java 21 and Spring Boot paired with RDBMS and NoSQL databases
• Experience with AWS and event-driven architectures.
• Experience delivering product-led, agile software.
• Strong stakeholder management across Product, Operations, and Engineering.
• Excellent communication skills, able to explain complex technical concepts to non-technical stakeholders.

Desirable

• Experience in financial services
• Experience improving operational resilience and throughput via system redesign and automation.
• Experience with agent-first organisations

What Success Looks Like

• Transfers systems are simpler, more resilient, and easier to change, with fewer incidents and faster recovery.
• Technical risks are surfaced and addressed early, enabling predictable delivery.
• Clear architectural direction reduces rework, inconsistency, and regret spend.

A chance to talk with our Hiring Manager in more detail about the role, our tech stack and some of the problems we solve every day.

Stage 2 – Technical (90mins):

For the technical part, we’d like you to sit down with some of your potential peers to work through a technical solution. We’ll be looking together at system design, deep-dive into areas like event-driven systems or migration paths for live systems, and how to influence your peers.
