Telness Tech is on a mission to simplify and digitize the telecom industry. Our platform powers next-generation mobile providers, from traditional MVNOs to eSIM challengers and non-telecom players looking to embed connectivity into their offerings. With our roots in Stockholm and our sights on a global scale, we’re building the future of telecom—fast, flexible, and customer-first.
As we accelerate our growth, we’re seeking Senior Software Engineers to help us become the global leader in #teltech.
About The Role
You will work with a team of skilled engineers and build modern architecture and technology. Our backend is built in Golang and runs in AWS using Kubernetes. Communication between backend services utilizes gRPC, and the frontend uses React. We use both GraphQL and REST, and primarily use PostgreSQL databases with event sourcing.
We are scaling up our platform to new markets with dynamic requirements, and you will play a crucial role in shaping, designing, and building fundamental components. As the company expands, you will help us tackle new and interesting challenges, scaling our platform from tens of thousands to hundreds of millions of users.
We have openings in multiple teams, and hiring will be based on your background, skills, and technical interests. For the right person, there are opportunities to take on a leading technical role, whether from day one or over time, helping the team build a clear technical vision and make strategic technology choices as we scale.
About You
You are an experienced Sr. Software Engineer who has probably worked at several companies, including at least one startup, and has grown with them from an early stage. You are currently working with Go (or a similar) in a full-stack, backend-focused role and are comfortable diving into occasional front-end work with React. You are excited about joining a startup journey where you will shape both product and technology while working in a small, high-autonomy team.
What You Bring To The Table
We’re not building for telco as it is—we’re building for how it should be: fast-moving, easy to use, and built for the people who use it. At Telness Tech, you’ll join a curious, ambitious, and transparent team. We work hard, we move fast, and we support each other every step of the way.
Here’s what you can expect:
