About Wolt
At Wolt, we create
technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of
restaurant food. Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries
around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the
globe.
Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more
than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with
drive and entrepreneurial spirit, this could be the ride of your life.
Who We Are Global Marts builds
the technology behind DoorDash's own grocery and retail operations across DashMart, Wolt Market, and Deliveroo Hop.
Our systems decide what products our stores stock, how much inventory to purchase, which vendors
to source from, how warehouses execute orders, and what prices customers see.
We build
everything from forecasting and replenishment systems to vendor management, warehouse execution, labor scheduling, space
optimization, and pricing. Our in-house forecasting platform has replaced third-party solutions and now powers production
globally.
This isn't a traditional CRUD backend environment. Much of our work involves
designing new systems that solve complex operational problems at global scale.
What You'll Do As a
Senior Backend Engineer, you'll work primarily with Go or Kotlin and take end-to-end ownership of production systems and complex
technical initiatives.
You'll:
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.
How We Work Autonomy & Ownership: Engineers have end-to-end
responsibility for their services, from design and implementation to production and on-call.
Collaboration: Architecture and technical
direction are shaped together. Senior engineers are expected to contribute actively to decisions and help others arrive at strong
solutions.
Scalability & Simplicity: We value pragmatic solutions that solve today's problems while providing a
sustainable foundation for tomorrow.
Impact: We work closely with Product, Data Science, and Operations, connecting technical decisions
directly to real-world retail and operational outcomes.
Our Tech Stack Our primary backend languages are Go and Kotlin.
We also use Kafka, PostgreSQL, MongoDB, Redis, Snowflake, AWS, Kubernetes, Docker, gRPC, GitHub
Actions, and modern cloud infrastructure.
You don't need experience with every technology
in our stack. We're more interested in strong backend and distributed systems fundamentals and your ability to learn and make
sound technical decisions.
Our Humble Expectations We're looking for engineers who:
Have strong experience
designing, building, and operating production backend systems.
Have professional experience with Go, Kotlin, or another modern backend language.
Have experience owning services end-to-end, including design,
implementation, deployment, monitoring, reliability, and production operations.
Have strong knowledge of backend and distributed systems fundamentals, including APIs,
databases, asynchronous processing, failure handling, testing, and observability.
Are 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 is a plus:
Forecasting, optimization, scheduling, recommendation, or
decisioning systems.
Grocery, retail, logistics, supply chain,
or warehouse technology.
ERP, vendor management, procurement,
or workforce management integrations.
Replacing third-party or
legacy platforms with internally built systems.
High-throughput event-driven or streaming architectures.
Why Join Us? You'll help build the technology that
powers DoorDash's global grocery and retail business, solving complex operational challenges across inventory, forecasting,
fulfillment, pricing, and supply chain.
You'll have significant ownership over the
systems you build and the opportunity to influence technical direction while working closely with experienced engineers, product
managers, data scientists, and operations teams across multiple markets.
📍 This role is
based in our tech hub in Helsinki or Stockholm. We work in distributed teams, but may not be able to support fully remote work or
relocation.
Next Steps We're reviewing applications on an ongoing basis, so don't
wait to apply. We'll get back to you as soon as possible.
