• Experience designing scalable systems with clear API/data-flow.
• Ability to balance short-term delivery with long-term maintainability.
• Comfortable engaging with stakeholders and clarifying requirements.
• Able to break work into vertical slices and plan edge cases.
• Experience with unit/integration/E2E testing is a plus.

Responsibilities

• Work directly with product, design, stakeholders, and other teams to understand requirements.
• Break work into vertical slices delivering real user value.
• Create implementation plans covering approach, edge cases, risks, dependencies.
• Build across .NET (backend) and React (frontend).
• Use AI tools to accelerate development.
• Write and maintain automated tests (Playwright for E2E).
• Demo early, gather feedback, and iterate quickly.
• Identify and manage dependencies proactively to avoid rework.

Job description

We’re moving towards a model where engineers own features end-to-end.

With AI speeding up implementation, coding is no longer the bottleneck. The focus has shifted to understanding problems, shaping solutions, managing dependencies, and delivering high-quality outcomes.

We’re looking for senior engineers who are comfortable taking a feature from idea → plan → build → test → release, while working closely with stakeholders and product teams.

What you’ll be doing

• Work directly with product, design, stakeholders, and other teams to understand requirements
• Break work into vertical slices that deliver real user value
• Create clear implementation plans (approach, edge cases, risks, dependencies)
• Build across .NET (backend) and React (frontend)
• Use AI tools (Claude, Copilot, etc.) to accelerate development
• Write and maintain automated tests (Playwright for E2E)
• Demo early, gather feedback, and iterate quickly
• Identify and manage dependencies proactively to avoid rework

What we’re looking for

Solid system design & engineering fundamentals

• Experience designing and building scalable, maintainable systems
• Strong understanding of APIs, data flow, and application architecture
• Able to make pragmatic design decisions balancing short-term delivery with long-term maintainability
• Comfortable engaging with stakeholders and asking the right questions
• Able to understand the \"why\" behind a feature
• Can work with ambiguous requirements and shape them into clear solutions

End-to-end ownership

• Can take a loosely defined feature and drive it through to delivery
• Doesn’t rely on fully defined tickets to get started
• Takes accountability for both outcome and quality

Strong slicing and planning skills

• Can break down features into well-sized vertical slices (~1-2 day chunks)
• Keeps work small enough to review and test effectively
• Avoids both over-granular tasks and overly large \"epic-sized\" work
• Builds with testing and reliability in mind
• Experience with unit, integration, and E2E testing (Playwright preferred)
• Thinks through failure scenarios, not just happy path

Dependency and change management

• Proactively identifies dependencies across teams or systems
• Flags risks early and works to minimise rework
• Comfortable operating in environments where things change mid-stream

Desirable - AI-assisted development (practical, not theoretical)

• Experience using tools like Claude Code, GitHub Copilot (or similar)
• Treats AI as an accelerator - validates output, handles edge cases, and maintains code quality
• Uses AI to speed up delivery without increasing risk
• Frontend: React (TypeScript preferred)
• Testing: Playwright (E2E), unit and integration testing
• Tools: Git, PR-based workflows, CI/CD

How we work

• Engineers own features, not just tasks
• Work is organised around vertical slices, not pre-defined tickets
• AI is part of the workflow - used to move faster, not to cut corners
• Focus is on delivering complete, usable features, not just closing stories

How you’ll be measured

• Feature delivery (cycle time and predictability)
• Quality (rework, stability, test coverage of key flows)
• Ability to clarify and shape requirements early
• Effectiveness in handling dependencies and reducing blockers
• Clear communication of trade-offs (scope, speed, quality)
• Work in a modern AI-assisted engineering environment
• High ownership and autonomy
• Real impact on how products are built and delivered
• Opportunity to help shape a new engineering model, not just follow one
