In addition, you’ll have the opportunity to join our partner track – for those who want to shape not only our work, but our future.
The Role
We’re looking for a Senior Backend Developer with experience in AWS, APIs, and integrations to join our team. You’ll take ownership of our API landscape and help scale a modern application stack with a focus on stable AWS-based services and integrations with external systems.
You’ll be working closely with product, frontend, and DevOps to design and build solutions that balance performance, security, and scalability.
What you’ll be doing
-
Designing and developing RESTful and event-driven APIs.
-
Building secure and scalable microservices.
-
Integrating with third-party systems such as CRMs, payment gateways, and external data sources.
-
Setting up DevOps pipelines and CI/CD on AWS.
-
Optimizing performance and error handling in production environments.
What You Bring
-
Experience with AWS services (Lambda, ECS, API Gateway, DynamoDB, RDS, etc.).
-
Skills in TypeScript or Python (or both).
-
Experience with test-driven development and logging.
-
Knowledge of OAuth, webhooks, and token-based security.
-
The ability to collaborate with frontend and DevOps for fast iteration.
-
(Bonus) Experience with GraphQL or event streams (Kafka/Kinesis).
What We Offer
- A strategic digital agency that combines business understanding, design, and tech.
- An ambitious team that values speed, substance, and a collaborative spirit.
- The chance to influence projects from first spark to final product.
- A grounded environment – just real people who care about good work.
- The opportunity become a partner at an ambitious and growing agency.
- We are flexible with working hours and remote work, but we expect you to be primarily physically present at the office, as we are in a formative phase of building the company.
Salary: 55.000-60.000 DKK (Depending on qualifications)
Start: As soon as possible.
