Frontend Developer – Ground Truth Production
We are on a mission to make autonomous vehicles possible. Help us realise our mission through effortless and efficient production of high-quality data in a user-friendly platform.
Annotell is a fast-growing startup on a mission to make safe perception for autonomous mobility possible. We provide our clients with the ground truth information to build and validate their systems and the insights to know they have the right data for their use case. That means we provide the labels telling what is in the data.
You will join the Annotation team within our Ground Truth Production product area. The team’s mission is to enable effortless and efficient production of high-quality ground truth. It is responsible for the tools used by annotators on camera, LiDAR, and radar data. The cross-functional team identifies valuable improvements and suitable solutions. Some current skills in the group include UX/UI design, frontend and backend development, and machine learning. We are now looking for additional product developers strong in frontend development to join.
What you will do
Our users’ job is to produce high-quality ground truth, and they rely on us to provide the tools enabling them to do that. Speed is essential, but also accuracy. We need to minimise the annotation time while keeping the quality high. A straightforward and precise UI for professional users is at the job’s core. 2D and 3D performance, as well as loading times, are other essential parts. Beyond the pure frontend parts, interactive machine learning tools can simplify or even automate many tedious tasks. Together with the team, you will prioritise what to build based on usage data and the value you expect from each solution.
As part of a team, you succeed with the team. At Annotell, we empower our teams to be bold and make decisions; you are the ones closest to the information. You own your mission, and you are vital for our success. Our teams are agile and self-improving. They discuss needs with users and clients and negotiate priorities with stakeholders. The teams are end-to-end responsible for the things they build.
Our tech stack
Our web app is modularly built using TypeScript and React. We develop our backend with Scala and Python and deliver the complete solution using Kubernetes on Google Cloud. We rely on ElasticSearch to enable real-time search capabilities.
Who you are
We are looking for several candidates with solid skills in building web applications using TypeScript and React. Experience in video, 3D, drawing apps, or experience using D3 or Three.js is a great plus. An interest in metrics or testing user interactions is also meritorious.
At Annotell, seniority means deepening and broadening individual skills, helping the team and colleagues grow and succeed, and improving the team’s effect by finding better solutions for more valuable problems. Seniority consists of both personal skills and understanding of the Annotell context. We are looking for both new senior colleagues and those earlier on their journey.
You will be a part of a team at a startup with grand ambitions where we help each other to ensure everyone succeeds as Annotell succeeds. We believe you are an excellent fit if you enjoy working in a growth environment where you sometimes have to act under uncertainties and if you appreciate the responsibility that comes with our mission-driven and self-organising style. You are always up for learning new things and are inspired by reaching challenging goals as a team.
What is in it for you?
Other than working with our excellent team in an inspiring and collaborative environment, we also offer you this:
- Strong values and purpose-driven company
- Being part of defining and building the ground truth product
- Workplace flexibility and work-life balance
- Competitive salaries
- Exciting career opportunities in a dynamic and fast scaling startup!
- Parental pay, salary exchange, maximum health benefit, order your workstation, 30 days vacation, place your pension – to name a few.
