Job description

About Motorway

Motorway is the UK’s fastest-growing used car marketplace – our award winning, online-only platform connects private car sellers with over 7,500 verified dealers nationwide, who compete to offer the best price. Founded in 2017, our technology makes the process refreshingly easy, earning us an 'Excellent' Trustpilot rating with over 70,000 reviews. We're not just building a platform; we're changing how people sell cars.

Backed by leading investors like Index Ventures and ICONIQ Growth, and following a successful $190 million funding round, we're on a mission to transform the used car market.

Why you should join us

At Motorway, we believe that the best products are built by passionate, product-minded engineers working together to do the best work of their careers. Our team has built and scaled systems at companies like Amazon, Instagram, Just Eat, Checkout.com, and Expedia. We're building the UK’s most powerful vehicle transaction platform, and you could play a key role in our next stage of growth and disruption.

Here are just a couple of the problems we're tackling:

• Building a platform that handles massive transaction volumes with speed and reliability.

• Using data and machine learning to provide accurate valuations and match sellers with the right buyers.

What you’ll do

• Architect and develop new Typescript code, focusing on new features and optimising performance.

• Enhance performance and caching strategies as our platform scales.

• Build highly maintainable, reusable, scalable, and reliable code (because nobody likes a code-astrophe!).

• Design sync and async APIs. We use OpenAPI and JSON Schema to bring a schema-first approach to our services.

• Manage our AWS infrastructure to ensure it's performing at its best, and keep a close eye on monitoring and alerting.

• Champion and implement software development best practices for high-quality, well-tested, and secure code.

• Contribute to the technical and product strategy of the business.

Experience you need to be successful

• Significant commercial experience with JavaScript and Typescript, particularly with modern features, and technologies like Node.js, Express, or Sequelize.

• Experience configuring, deploying, and monitoring applications and websites on AWS, specifically Lambda, Fargate, Aurora, DynamoDB, S3 and Eventbridge.

• Comfortable working with relational and NoSQL databases, including complex queries and performance optimisation.

• A solid understanding of web design patterns, including SOLID principles.

• Experience working in a collaborative, agile team environment.

Our tech stack

We use:

• Typescript and Node.js: We love Typescript for its maintainability and scalability, and Node. js lets us build fast, efficient backend services.

• React: To create smooth, responsive user interfaces.

• AWS (Lambda, Fargate, Aurora, DynamoDB, S3, Eventbridge): We leverage AWS for its reliability, scalability, and the breadth of services it offers.
