Company mission
To solve AI alignment by tackling the real bottleneck: data quality.
Role
Who you are
- You've seen and built a lot. You have personally developed and maintained multiple systems from scratch, and you know what trade-offs are involved in building reliable, performant software at speed
- You want your work to have a tangible outcome for people. You're not satisfied with building products that do not see the light of day
- You are a builder. You enjoy all aspects of building not only software but a complete product, and are comfortable moving across the stack when necessary
- You enjoy problem-solving and thinking from first principles, and are always ready to pick up new skills and build quickly
- You're happy to tackle problems without a predefined, clear definition or obvious solution, and are excited to have autonomy to make decisions as you go
- You understand that being a member of a high-performing team requires two things. You contribute your best work and help others contribute their best. You'll always lend a helping hand when needed and level up those around you
- Strong experience building large-scale backend infrastructure applications
- Deep fluency in at least one high-level language (we use Python and TypeScript, but we care more about depth than the specific language)
- Experience improving quality through code reviews, testing, rollout, and monitoring
- Experience with prompt engineering, agent orchestration, and the ability to integrate AI tools to optimise workflows and drive measurable impact
- Experience in robotics, autonomous vehicles, or Physical AI is a plus
What the job involves
- We're looking for an outstanding engineer to push our platform to the next level
- You'll join us at a crucial stage of accelerated development for the company, product and team
- As part of a small, highly collaborative group, you'll drive our product and team to new heights
- Encord is growing rapidly, with our product as the key driver of that growth. A year ago, we were a team of 25; now, we’re 60 and continuing to accelerate
- Be a part of the small team that has built a product that our customers love and consistently rate as the best in the market
- Have a direct and tangible impact on customers and, in turn, noticeably affect the trajectory of the company
- Work autonomously and take end-to-end ownership of your projects. From product, design and architectural decisions, all the way to deployment, monitoring and measuring impact on users
- You will work across the stack, covering everything from deployment to styling
- We expect each other to take initiative, be proactive in problem-solving, and continuously seek improvements
- Tackle complex domains and immense scale with simple solutions
- Tech stack:
- We are technology-agnostic at Encord and are not looking for experience across all of these — as long as you're open to learning, please apply
- Backend: Python
- Frontend: TypeScript and React
- Deployment: Kubernetes
- Infrastructure: GCP
- Machine learning: PyTorch, CUDA, Ray

Our take
It has become increasingly clear that the next generation of AI applications will be driven by data-centric approaches concentrated around training data creation, management, and evaluation. Crucial within this process is the annotation or 'labelling' of data. Traditionally, such annotation has been left to human workers, which has historically made this part of the process of AI development expensive, slow, and difficult to scale.
Encord offers a computer vision annotation platform that automates a number of manual labelling tasks. Its suite of tools is designed for collaboration across roles and teams, from domain-expert annotators to project managers and machine learning engineers. This allows companies to iterate 10x faster, and develop and deploy high performing models in less time whilst saving on annotation costs.
Demand is clearly there: since its launch in 2020, Encord has facilitated the annotation of more than 100 million frames and images and served customers in verticals such as medical imaging, smart cities, sports analytics and satellite imaging. Furthermore, usage is scaling rapidly, with the number of labels generated on the platform growing ~70% month-over-month.
