We are looking for a Senior Full-Stack Engineer to help build and evolve our new Common case-management system, powering support-case handling across DoorDash, Wolt, and Deliveroo.

You will own significant end-to-end initiatives across backend services and agent-facing tools: case lifecycle, routing and assignment, queue management, case evidence and history, and migration from legacy systems. This is a hands-on product engineering role for someone who can turn ambiguous customer and operational problems into durable technical solutions.

What you’ll do

• Lead one or more project-level Case Management initiatives from discovery and design through rollout, measurement, and operational ownership.
• Build scalable backend services and React-based internal tools used by support operators and administrators.
• Design reliable case-management capabilities, including case creation, routing, assignment, transfers, audit history, notes, attachments, and queue-management workflows.
• Help deliver feature parity with legacy platforms while safely migrating traffic across DoorDash, Wolt, and Deliveroo.
• Make and own technical decisions within your scope; write project-level design documents, identify dependencies and risks, and break work into parallelizable delivery plans.
• Partner closely with Product, Operations, Support, Data, and other engineering teams to define the right customer problems and improve the roadmap.
• Raise the quality bar through thoughtful design reviews, observability, testing, incident response, documentation, and reusable patterns.
• Mentor engineers through code reviews, technical guidance, and constructive feedback.

Must-have qualifications

• Strong full-stack engineering experience, including production React and TypeScript experience.
• Strong backend engineering experience, including designing and operating backend services, APIs, asynchronous workflows, and data models at meaningful scale.
• Demonstrated ownership of complex, customer-facing or operations-critical projects from technical design through production rollout.
• Hands-on experience using AI development tools to improve engineering productivity, while validating generated output for correctness, security, privacy, maintainability, and reliability.
• Strong product judgment: able to translate ambiguous workflows and user needs into simple, maintainable technical solutions.
• Proven ability to collaborate across functions, drive alignment, and communicate trade-offs clearly to technical and non-technical stakeholders.
• Strong software-engineering craft: testing, code review, observability, incident response, security, and operational readiness.
• Comfortable working on systems with high correctness and auditability requirements, including traceability of decisions and changes.
• A proactive mentoring mindset and willingness to raise team-wide engineering standards.

Nice-to-have qualifications

• Go experience.
• Experience with migration from legacy systems, gradual rollouts, traffic shadowing, and feature-parity programs.
• Experience building internal tools or operational user interfaces.
• Experience with high-volume, multi-region, or multi-tenant systems.

What success looks like

• Delivers a major Case Management initiative with clear technical ownership, predictable execution, and measurable customer or business impact.
• Improves the Common system’s reliability, usability, and maintainability while enabling safe migration from legacy case-management systems.
• Helps move support traffic onto the Common system without reducing case-resolution quality.
• Builds solutions that other engineers and operators can confidently reuse and operate.
• Acts as a technical leader within the team: unblocks peers, improves engineering decisions, and strengthens cross-functional execution.
