This is a full-time, on-site position based in Copenhagen. We do not offer a relocation package, but we can help with your visa if you are working in Denmark and on a visa.

Would you like to help companies be more human on the Internet? At TwentyThree we do that the best way we know – with video.

The Role

You will be moving our product forward and defining how we build the backend/cloud-native parts of our video suite. You will build systems from scratch and impact the whole company. This role requires strong technical and collaboration skills.

Be curious, keen on learning, take ownership of your work and we will support your growth to where you would like to take your career. It’s okay not to know everything if you want to learn.

You will work with the engineering leadership on defining how we build software. You will work with the product team on understanding our product, and with the rest of the engineering team on delivering new software. You will be working on a team of three people with a planned extension to four. The whole engineering department consists of ten people.

You will be evangelizing for quality, best engineering practices and mentoring the rest of the engineering team and the organization. Help resolve technical discussions and manage the technical quality of team deliverables. Promote collaboration and engagement within the team and across the whole organization while building solid relationships with all relevant stakeholders.

What Success Looks Like

• We deliver a piece of new functionality using TypeScript/node.js.

• We remove a piece of functionality from existing Tcl-based codebase.
• We lay foundations to how we write TypeScript backend.

Ideally…

• You have prior experience writing backend TypeScript software.
• You write code that can be maintained by somebody else; a newcomer should be able to pick up your code in a few years.
• You write tests.
• Your code is predictable.
• Your code is easy to operate and reports on internal metrics.
• Your code is highly cohesive and loosely coupled.
• You enjoy working together as a team with regular pair programming.
• You don’t mind occasional legacy code spelunking when it’s for the greater good—to understand an old system so that we can port the functionality.
• You ask “but why?!” and challenge the status quo.
• You have prior experience with event-driven programming and architecture.

Projects

We want to enable people on our engineering team to extend the backend parts of the product, delivering product functionality faster. If you are now thinking “technical debt,” you are correct—we have a dependency on a codebase using Tcl (the programming language, pronounced as “tickle”) which has been slowing us down, and we would like to fix that. We want to achieve this by transitioning our backend from Tcl to TypeScript.

All projects will stem from this foundation: build modern software enabling the engineering team, consolidate our technical stack and deliver value to our customers. Some of the projects that we have lined up:

• Enable webinar recordings across different providers of WebRTC infrastructure.
• Implement machine learning/AI tools to enhance customer experience when working with video.
• Implement authentication system which supports “bring your own SSO” for customers, and which will allow us deprecate old systems.
• Bring event-driven architecture into our asynchronous operations: analytics, video transcoding and transcription and others.

The Tech

Our tech stack has evolved significantly over the years. While Tcl has been the backbone of our codebase, now it’s time for the next step—moving to TypeScript, consolidating our varied stack.

We generally run with a flavour of DevOps culture with a platform/SRE team being responsible for the underlying infrastructure and helping the team taking care of our production deployments.

We take pride in our platform, and we keep iterating on it. Our production runs on top of Kubernetes in AWS. We store data in Postgresql, Redis, S3 and we exchange messages via RabbitMQ when needed.

Working at TwentyThree

We offer a competitive salary with three months of fully paid parental leave & five weeks of paid vacation. You will participate in the company bonus scheme “The Pool” that shares a percentage of EBITDA with all employees.

TwentyThree is a very social and international company. We often connect with our customers by going to events and conferences, and by organising our own events. Right now we are preparing a summit for ~600 people that we’ll hold in our office. The team currently counts 18 different nationalities.
