Role Overview
The Principal Software Engineer provides the technical leadership, architectural vision, and engineering standards required to evolve and scale the Field Platform. The role ensures that our platform delivers a unified, performant, secure and resilient experience that enables thousands of field colleagues to work efficiently, safely and effectively every day.
Responsibilities
- Define & evolve the Field Platform architecture: set the long‑term architecture, patterns, and guardrails for Field platform services to ensure scalability, resilience, interoperability, and a unified experience.
- Drive consolidation and simplification of the estate: lead the rationalisation of the platform into a coherent platform, reducing duplication, technical debt, maintenance costs, and operational complexity.
- Shape cross‑domain technical design decisions: partner across Product, Architecture, Supply Chain, Scheduling, and Field Operations to drive consistent data models, integration patterns, UX principles, and standards across all field workflows.
- Identify and deliver new digital capabilities: work with product and business leaders to define new capabilities such as supply chain, quoting, workflow optimisation, and knowledge management to enhance safety, compliance, customer experience, and productivity.
- Establish engineering excellence across teams: champion high engineering standards including clean architecture, CI/CD automation, observability, testing strategies, release processes, telemetry, performance tuning, and secure‑by‑design principles.
- Lead platform performance, reliability & offline capability: ensure the environment performs reliably in challenging field conditions such as poor signal or offline mode.
- Influence and steward Security, SRE, Quality and Platform‑wide capabilities: shape quality, resilience and security strategies across teams.
- Continuously improve how work is done: identify opportunities to automate, simplify, reduce cycle time, improve developer experience, adopt new tools and AI, and scale better engineering practices.
Key Stakeholders
The Principal Software Engineer works closely with the Head of Engineering, Product Managers, and Field Operations SMEs. The role also collaborates with external partners and tooling providers such as Microsoft and Datadog.
Leadership & Influence
Lead through influence and expertise, shaping backlog, standards and adoption; coach analysts/engineers; model product‑led, iterative delivery and high standards of quality and controls.
Qualifications
