Описание
Global Marts builds the technology behind DoorDash's own grocery and retail operations across DashMart, Wolt Market, and Deliveroo Hop. This involves designing new systems that solve complex operational problems at global scale, from forecasting and replenishment to vendor management, warehouse execution, labor scheduling, space optimization, and pricing.
Responsibilities
- Design, build, and operate backend systems that support inventory, purchasing, warehouse operations, pricing, and fulfillment.
- Own technical solutions from problem definition and design through implementation, deployment, monitoring, and production operation.
- Work on data-heavy systems where software engineering meets forecasting, optimization, and operational decision-making.
- Turn complex and sometimes ambiguous business problems into pragmatic, scalable technical solutions.
- Make and influence architectural decisions, balancing scalability, reliability, development speed, and long-term maintainability.
- Collaborate closely with engineers, product managers, data scientists, and operations teams to shape solutions and technical direction.
- Improve the reliability, observability, scalability, and operational excellence of the systems you own.
- Support and raise the engineering standards of the team through technical discussions, code reviews, and knowledge sharing.
- Use AI-assisted development tools effectively while applying strong engineering judgment to validate their output, improve development velocity, and identify opportunities where AI can create additional leverage.
Requirements
- Strong experience designing, building, and operating production backend systems.
- Professional experience with Go, Kotlin, or another modern backend language.
- Experience owning services end-to-end, including design, implementation, deployment, monitoring, reliability, and production operations.
- Strong knowledge of backend and distributed systems fundamentals, including APIs, databases, asynchronous processing, failure handling, testing, and observability.
- Comfortable working with data-heavy systems and technologies such as Kafka, Snowflake, or similar streaming and data infrastructure.
- Can navigate ambiguous problems, break them into actionable steps, make appropriate technical trade-offs, and deliver incrementally.
- Can influence technical decisions beyond their immediate tasks and collaborate effectively with engineers and cross-functional partners.
- Communicate technical concepts and decisions clearly and concisely.
- Use AI-assisted development tools effectively in their everyday engineering workflow while critically evaluating generated solutions and taking full ownership of the resulting code and technical decisions.
- Look for opportunities to use AI to improve engineering productivity and solve problems more effectively, while understanding where human engineering judgment remains essential.
Nice to have
- Experience in one or more of the following: forecasting, optimization, scheduling, recommendation, or decisioning systems.
- Experience in one or more of the following: grocery, retail, logistics, supply chain, or warehouse technology.
- Experience in one or more of the following: ERP, vendor management, procurement, or workforce management integrations.
- Experience replacing third-party or legacy platforms with internally built systems.
- Experience with high-throughput event-driven or streaming architectures.
We offer
- This role is based in Wolt's tech hub in Helsinki or Stockholm.
- Wolt works in distributed teams, but may not be able to support fully remote work or relocation.
- Engineers have end-to-end responsibility for their services, from design and implementation to production and on-call.
- Architecture and technical direction are shaped together.
- Wolt values pragmatic solutions that solve today's problems while providing a sustainable foundation for tomorrow.
- Wolt works closely with Product, Data Science, and Operations, connecting technical decisions directly to real-world retail and operational outcomes.
