Software Engineer (Backend)

⚠️ PLEASE READ FIRST

As a Software Engineer (Backend), you will play a vital role in building and scaling the services and pipelines that power our products. You'll work closely with our customers, product team, and 3D team to design and maintain reliable backend systems that support our 3D production workflows and internal tools.

• This is a full-time, in person, based in our London office, five days a week

• Salary: £45k - £85k depending on experience + equity

• We provide visa sponsorship for UK and Singapore offices

ABOUT KAEDIM

Kaedim is an a16z-backed startup that raised $15M in our Series A to build the data infrastructure powering the next generation of robot training. We're hiring Backend Software Engineers for our London and Singapore offices.

Our AI pipeline turns 3D assets and real-world environments into validated, sim-ready datasets at the quality and scale robotics companies need to close the sim-to-real gap. We sit at the intersection of generative 3D, physics simulation, and physical AI, and we're just getting started. Explore what we're building at projectsim.ai

HOW WE WORK

We're a small, ambitious team that moves fast and takes real ownership of our work. Everyone is in the office five days a week, typically 9 to 9, because we're genuinely excited about what we're building and want to see it ship.

WHAT YOU'LL DO

• Collaborate with cross-functional teams to design, develop, and deploy backend services that meet customer and internal workflow needs

• Build and maintain robust APIs (REST and internal services) that power our web application and artist tools

• Write clean, modular, and maintainable backend code using NodeJS and Express (and Python where appropriate)

• Design, implement, and tune MySQL schemas and queries to ensure efficient, reliable data storage and retrieval

• Manage and optimize AWS cloud infrastructure and services (e.g. EC2, S3, RDS), applying security, reliability, and cost-efficiency best practices

• Implement and improve monitoring, logging, and alerting to ensure system reliability and fast incident response

• Conduct unit and integration testing (e.g. Jest, Cypress for API flows) to ensure backend stability and correctness

• Work independently to drive projects from idea to production, including scoping, implementation, and iteration

• Partner with frontend engineers and other stakeholders to define API contracts and data flows

• Stay up-to-date with emerging backend technologies, infrastructure tools, and best practices in distributed systems and web services

WHAT YOU'LL BRING

• Strong experience building backend services in NodeJS and Express (or similar frameworks)

• Solid experience with Python for backend systems, scripting, or data/ML integration

• Strong knowledge of MySQL (or similar relational databases) and sound database design principles

• Experience designing and implementing REST APIs and working with modern web application architectures

• Practical experience with AWS (e.g. EC2, S3, RDS) or another major cloud provider for deploying and operating backend services

• Experience with automated testing for backend systems (unit, integration, and/or end-to-end tests)

• Strong debugging and troubleshooting skills across backend services, data flows, and infrastructure

• Excellent collaboration and communication skills, including the ability to work in a fast-paced environment with cross-functional teams and manage multiple projects simultaneously

NICE TO HAVE

• Experience in robotics or simulation (for example ROS, Isaac Sim or MuJoCo), or building tooling and data pipelines for robotics and ML teams

• Familiarity with observability tooling (metrics, traces, logs) to monitor and improve system performance

• Exposure to 3D-related workflows, or experience integrating backend services with 3D or graphics-heavy applications

• Experience with 3D modelling or 3D content pipelines is a plus
