# Senior Backend Engineer - Case Management **Company**: Deliveroo **Location**: London, England **Experience**: senior **Job type**: full-time **Category**: Engineering **Industry**: Technology **Apply**: https://job-boards.greenhouse.io/deliveroo/jobs/8206349?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply **Canonical**: https://yubhub.co/jobs/job_51dc815f-685 ## Description We are looking for a Senior Backend Engineer to help build and evolve our new Common case-management system, which powers support-case handling across DoorDash, Wolt, and Deliveroo. You will own significant end-to-end initiatives across our backend services: case lifecycle, routing and assignment, queue management, case evidence and history, and migration from legacy systems. This is a hands-on role for someone who can turn ambiguous customer and operational problems into durable technical solutions, coordinate other engineers, and set the standard for reliability and craftsmanship on the team. ## Responsibilities - Lead one or more project-level Case Management initiatives, on your own or by guiding a group of engineers, from discovery and design through rollout, measurement, and operational ownership. - Design and build scalable backend services and APIs for 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 most technical decisions within your scope. Write project-level design documents covering how sub-features interact, identify dependencies and risks, and break work into parallelizable delivery plans. - Scope ambiguous customer and operational problems, weigh long-term against short-term trade-offs, and design durable solutions. - Partner with Product, Operations, Support, Data, and other engineering teams to define the right problems. Shape the team roadmap through prototypes, data analysis, project proposals, and backlog prioritization. - Run the coordination a project needs, such as status updates and dependency tracking, and escalate early to keep delivery on time. - Enforce team-wide quality objectives: lead design reviews, calibrate quality metrics, and improve logging, monitoring, alerting, and escalation policies. - Serve as first responder or incident commander, model good incident practice, and turn what you learn into playbooks and backlog work. - Introduce and guide AI best practices for the team, including evals, data privacy, and review of AI-generated code, and take part in AI-powered projects when they are central to the product. - Design reusable, self-serviceable solutions, and consider cost efficiency, including compute and AI costs, in key designs. - Mentor engineers through code reviews, design guidance, tech talks, and constructive feedback. Interview candidates, join sell calls, and take part in hiring events when the team needs them. ## Requirements - Strong backend engineering experience, including designing and operating backend services, APIs, asynchronous workflows, and data models at meaningful scale. - Proficiency in at least one modern backend language, and a record of writing exemplary code for the core functionality of key components. - Demonstrated ownership of complex, customer-facing or operations-critical projects from technical design through production rollout. - Experience breaking projects into parallelizable work, identifying dependencies and risks, and giving accurate estimates for yourself and others. - Hands-on experience using AI development tools to improve productivity, while validating generated output for correctness, security, privacy, maintainability, and reliability. - Strong product judgment: the ability to turn ambiguous workflows and user needs into simple, maintainable technical solutions. - Proven ability to collaborate across functions, bring the right stakeholders into decisions at the right time, and explain trade-offs clearly to technical and non-technical audiences. - Strong engineering craft: testing, code review, observability, incident response, security, and operational readiness, with experience designing for reliability. - Comfort working on systems with high correctness and auditability requirements, including traceability of decisions and changes. - A mentoring mindset and a record of raising 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 supporting internal tools or operational user interfaces from the backend side. - Experience with high-volume, multi-region, or multi-tenant systems. - Experience as an incident commander or in running an on-call rotation. - Experience building AI-powered features, including evaluation of model output. ## What success looks like - Delivers a major Case Management initiative with clear technical ownership, predictable execution, and measurable customer or business impact. - Improves the reliability, maintainability, and cost efficiency of the Common system 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 and partner teams, improves engineering decisions, influences the roadmap, and strengthens cross-functional execution. ## Skills ### Required - backend engineering - API design - async workflows - data models - modern backend languages - AI development tools - testing - code review - observability - incident response - security ### Nice to have - Go - migration from legacy systems - gradual rollouts - traffic shadowing - feature-parity programs - high-volume systems - multi-region systems - multi-tenant systems - incident commander - AI-powered features --- Source: [Apply at job-boards.greenhouse.io](https://job-boards.greenhouse.io/deliveroo/jobs/8206349?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
