Senior Backend Engineer

Join Us in Building the Future of B2B Payments

At Ledyer, we are building the next generation of solutions for B2B payments. Our ambition is simple: buying and selling between businesses should be just as smooth as it is for consumers.

We are now looking for a Senior Backend Developer who wants to help build the systems at the core of our platform. You will be a key part of our engineering team, with significant technical responsibility and the opportunity to influence our architecture as well as our products and ways of working.

We are looking for someone who is based in Stockholm and speaks fluent Swedish.

Engineering at Ledyer

Technology is at the core of everything we do. We work in small, cross-functional teams with clear ownership and a shared focus on delivering real value to our customers.

As a senior developer with us, you are not just expected to write code. You participate in making technical decisions, challenge existing solutions, and take responsibility all the way from idea and architecture to production, monitoring, and ongoing development.

We believe in short feedback loops, automated testing, observability, and continuous improvements. We value pragmatic technical decisions over perfection and want to build systems that are robust, understandable, and easy to maintain and evolve.

What You Will Do

As a Senior Backend Developer, you will, among other things:

• Build and further develop products within payments, identification, and B2B commerce.

• Design, implement, test, deploy, and maintain scalable backend services.

• Take substantial responsibility for architecture and technical choices.

• Build systems where reliability, security, and correctness are paramount.

• Work closely with product, design, and other engineers to solve real customer problems.

• Contribute to high quality through code reviews, knowledge sharing, and technical discussions.

• Improve our tools, processes, and ways of working.

• Explore new technologies and help us make informed decisions about what we should—and shouldn't—use.

Our Tech Stack

You will be working with, among other things:

• Golang

• gRPC

• AWS, including CDK, ECS, Fargate, CloudFront, and OpenTelemetry

• Temporal

• CockroachDB

We don't expect you to already be an expert in everything we use. Technologies change, and we value problem-solving skills and the eagerness to learn above experience with the exact right set of tools.

Who We Are Looking For

This is a senior role, and we are looking for someone with several years of experience in backend development who is comfortable taking on significant ownership.

We think you will thrive with us if you:

• Have solid experience in building backend applications and distributed systems (5+ years).

• Can reason about architecture, scalability, performance, and reliability—and understand the trade-offs that different solutions entail.

• Are accustomed to taking end-to-end ownership of systems all the way to production.

• Have experience with or a strong interest in cloud infrastructure, DevOps, and Infrastructure as Code, preferably within AWS.

• Care about code quality, testing, and observability.

• Enjoy working closely with product and business stakeholders, not just following a technical specification.

• Are curious, unpretentious, and enjoy solving complex problems together with others.

• Are based in Stockholm and speak fluent Swedish.

It is an extra plus if you have worked with:

• Payments or fintech.

• E-commerce.

• High-transaction systems.

• Mission-critical systems where correctness and high availability are essential.

What You Get at Ledyer

Ledyer is still a small company. That means you will be close to the product, our customers, and the decision-making—and that what you build truly matters.

With us, you get:

• High ownership. You get the responsibility and authority to influence both what we build and how we build it.

• Technical impact. As a senior developer, you help shape our architecture, engineering culture, and technical direction.

• Real, complex problems. Payments, identity, credit, and B2B commerce bring plenty of interesting technical challenges.

• Talented colleagues. You work with people who enjoy challenging each other's ideas, sharing knowledge, and building together.

• An opportunity to grow with the company. You join at a stage where a lot can still be influenced and shaped.

Life at Ledyer

We are a Stockholm-based fintech company that believes in a blend of flexibility and actually working together.

We work hybrid with a mix of remote work and time spent together at our office in central Stockholm. To us, the office isn't just a workplace—it's where many of the best discussions, decisions, and ideas come to life.

We also enjoy spending time together outside of daily development, whether it's over lunch, at conferences, during team activities, or tackling a tough problem together in front of a whiteboard.

Our culture is built on curiosity, transparency, responsibility, and collaboration.
