Senior Software Engineer

London (temporarily remote)

Do you want to Superpower Engineering? We’ve doubled in size over the last year, and we have ambitious plans moving forward. It’s very exciting! To continue in our growth, we are recruiting a Senior Software Engineer, to drive us forward and deliver the next-generation AI platform for engineers.

What you’ll be doing:

You’ll be working on developing the Monolith AI software platform, designing, and coding new features whilst building a scalable and robust system. You will work closely with the Product and Data Science teams implementing new features which could be anything from introducing a new queuing system to optimising the performance of a data loader. You’ll be designing solutions and working with clients to ensure they are able to get the most from the platform. We work in an Agile manner and encourage everyone to be looking to improve themselves and the company. The role is primarily for a back-end engineer, but any full stack experience is a bonus.

Let us tell you about the tech:
The platform consists of several microservices, built in Python (Flask), with the frontend built in React. The platform handles everything from authentication to data management (PostgreSQL), through to data processing and machine learning work (primarily written by Data Scientists using Pandas, Scikit Learn and TensorFlow). We deploy in a variety of environments, including AWS, Azure, private clouds, and on-premise HPC (High-Performance Computing) clusters. We are primarily looking for a backend developer, though any experience in Javascript frontend is of interest. Similarly, any experience of DevOps (we use Docker containers and Hashicorp Nomad for job orchestration) is a bonus.

You’ll be responsible for:  


  • Delivering features writing robust, maintainable code. 
  • Designing solutions using the latest software engineering practices. 
  • Maintaining and supporting customer platforms. 
  • Working in an agile manner, planning sprints, and helping to improve team processes. 
  • Collaborating with other software engineers to learn together and constantly improve the platform. 

A bit about you:

  • You love to solve complex problems. 
  • You can work collaboratively in a team to achieve goals. 
  • You can handle rapidly changing requirements. 
  • You understand and can implement the whole software lifecycle. 
  • You can write clean and maintainable code. 

It’s a bonus if you have:

  • A Physics, Maths or Engineering degree. 
  • Knowledge of AI or Machine Learning. 
  • Experience scaling a start-up.  
  • Previously designed and worked with microservices. 
  • DevOps knowledge.
