Job description

Tilt

Our mission is to make fashion accessible to all and inspire everyone to dress a little better. We believe e-commerce is in a rut, with brands lost in a decades-long void, lacking innovation, and mindlessly redesigning websites without fixing the real issue — making shopping fun and affordable.

Today, we are the UK's biggest live shopping platform focused on making shopping a joyful, social experience that brings people together and helps everyone level up their style. We've raised an $18m Series A, and we're rapidly growing and looking to hire A-players to build the future of shopping.

Your Mission

As a Senior Backend Engineer on our Seller Experience team, you'll be instrumental in building and scaling the systems that power our seller platform. Working within an autonomous squad, you'll develop the infrastructure and services that enable sellers to thrive on our platform. You'll be responsible for:

• System Architecture: Designing and implementing highly scalable backend services and APIs that power our seller tools, from shipping integrations to AI-driven features.

• Technical Innovation: Creating robust, maintainable solutions for complex seller-focused challenges while ensuring optimal performance and reliability.

• Infrastructure Development: Building and maintaining the cloud infrastructure that supports our growing seller ecosystem, ensuring high availability and scalability.

You must be prepared to jump into a start-up environment; if you're risk-averse this isn't the right place for you. We seek passionate, driven individuals eager to learn quickly, work hard, and help us shape the future.

Technical stack and tools

• Our frontend is built with VueJS and TypeScript.

• On the backend we mainly use NodeJS.

• On mobile we use native iOS (Swift, SwiftUI and UIKit) and native Android (Kotlin and Jetpack Compose) with a shared layer of KMP.

• Other core technologies include AWS, Express, Vite, Webpack, NPM, Cypress, GraphQL, and more.

About you

• Strong experience developing and deploying highly scalable applications and APIs in production environments.

• Deep knowledge of the NodeJS ecosystem and its associated technologies.

• Extensive experience with AWS services and infrastructure as code.

• Strong foundation in database design and management, particularly with relational databases.

• You're an ambitious problem-solver who thrives in fast-paced environments.

• You communicate technical concepts clearly and work effectively in autonomous teams.

• You're passionate about building systems that empower sellers and enhance their experience.

Bonus skills

• Experience with frontend technologies (VueJS, React).

• Expertise with NestJS framework.

• Proficiency in GraphQL API development.

• Experience with AWS Typescript CDK.

• Knowledge of document databases (MongoDB, DynamoDB).

• Experience with AWS Data Pipelines (Glue, SageMaker).

Location

We're open to hiring remotely within 2 hours of UK time.
London-based candidates can join us at our Canary Wharf Office (most engineers do 3 days a week).

Perks and benefits

We offer a competitive salary package including:

• Equity through stock options.

• Tech Budget.

• Workspace in London (Canary Wharf), including free gym membership.

Who we are

As a fast-growing platform, we value innovation, autonomy, and rapid iteration. We believe in empowering our teams to make decisions and move quickly. We're building something unprecedented in the e-commerce space, and we need passionate people who share our vision of making fashion more accessible and enjoyable for everyone.

We are committed to creating an inclusive and diverse work environment. We welcome applications from candidates of all backgrounds, regardless of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
