As a Lead Engineer within our new Digital Office, you will play a critical role in accelerating Expereo's transformation through the Single-Threaded Owner (STO) model. Operating within either the Commercial XP or In-Life XP STO, you will join a full-stack, outcome-driven squad focused on delivering intuitive, performant, scalable digital experiences across the Expereo customer journey.

You will design and build modern front-end and back-end applications, mentor engineers, shape engineering best practices, and contribute to a truly programmable, automated digital platform. This role is ideal for engineers who thrive in high-impact, cross-functional environments and enjoy building elegant user experiences backed by robust, scalable distributed systems.

Full-Stack Application Development

• Lead the design and maintenance of scalable front-end applications (React, Vue, Angular) and back-end services (Node.js, Python, or similar), creating reference implementations and documentation for the team to follow.
• Develop reusable UI components, design systems, shared libraries, and internal service frameworks.
• Build and integrate APIs (REST, GraphQL, event-driven and microservices architectures).

Performance, Quality & Reliability

• Ensure applications meet the highest standards of performance, security, accessibility, and reliability.
• Lead automated testing across unit, integration, contract, and end-to-end layers.
• Implement observability in both front-end and back-end systems, including logging, metrics, tracing, and alerting.
• Champion reliability engineering practices and performance optimization.

Automation & Platform Engineering

• Contribute to and evolve CI/CD pipelines, build tooling, infrastructure automation, and quality gates.
• Drive engineering standardization across STOs, including coding guidelines, architectural patterns, and platform abstractions.
• Lead initiatives that reduce friction, improve developer experience, and accelerate delivery cycles.

Technical Leadership & Innovation

• Partner with designers, architects, product managers, and engineers to ensure the technical direction aligns with long-term platform goals.
• Partner directly with designers and your team's Product Manager to evaluate the technical feasibility of new capabilities and provide effort estimations.
• Foster a high-ownership engineering culture through active mentorship and by setting the bar for code quality and testing layers.
• Lead explorations of new technologies, including agentic AI enablement, data-driven UX, programmable networks, and developer tooling.
• Contribute to reference implementations, architectural blueprints, and engineering guardrails.
• Identify technical risks early in the product lifecycle and propose pragmatic solutions to mitigate them.

• You treat the product as your own and prioritize long-term stability over short-term "hacks".
• Code-first and automation-first approach to solving problems.
• You are eager to work across the full stack and stay curious about the evolving tech landscape.
