Job description

About Tilt

We’re building the next century of shopping—making it feel human, communal, and alive again. E-commerce has spent decades optimizing for clicks, stripping away the trust, joy, and connection that once made shopping meaningful.

We’ve recently raised an $18M Series A from the world’s best investors to build the next era of commerce. Now, we’re hiring elite builders to make it happen.

About the Role

We're looking for a Senior Backend Engineer to help architect and scale the systems that power Tilt—from livestreams and checkout to auctions, personalization, and payments. You'll join our Core team : a small, high-leverage group responsible for foundational infrastructure, performance, and reliability.

This role is for builders who thrive in fast-moving environments, think like owners, and aren’t afraid to dive deep into gnarly systems problems. You’ll collaborate closely with product engineers, infra specialists, data scientists, and leadership.

In this role, you will :

Design and build scalable APIs and backend services that support millions of real-time user interactions

Own core infrastructure across streaming, payments, auctions, and real-time bidding

Improve performance, reliability, and observability across the stack

Collaborate across teams to ship systems that are fast, resilient, and developer-friendly

Help define and evolve backend best practices as we scale the team

Location :

This is a remote role, but you may be occasionally asked to work from co-working spaces in Toronto .

Who You Are

You’re an ambitious and entrepreneurial engineer who wants to help build something iconic. You’re motivated by impact, not ego. You move quickly, sweat the details, and love working with others who do the same.

We’re looking for :

5+ years of experience building production-grade systems

Experience working in early-stage startups or high-growth environments

Expertise in the Node.js ecosystem

Strong understanding of backend architecture and scalable system design

Deep experience with AWS and infrastructure-as-code (ideally with TypeScript CDK)

Fluency with relational databases and data modeling

A clear communicator—written, visual, and verbal

Self-directed and comfortable in a high-autonomy, low-ego culture

Bonus points for :

Experience with NestJS or similar backend frameworks

Familiarity with GraphQL APIs

Knowledge of document databases like MongoDB or DynamoDB

Exposure to frontend frameworks (Vue or React)

Our Stack

Frontend : Vue, TypeScript

Backend : Node.js, NestJS, GraphQL

Infra : AWS, TypeScript CDK, Docker

Mobile : Native iOS (Swift), Native Android (Kotlin) with shared KMP layer

Why Tilt

You’ll be joining a mission-driven team backed by world-class investors ( TechCrunch )

You’ll own meaningful systems from day one, with real scope and autonomy

You’ll work alongside curious, kind, and wickedly smart teammates

You’ll help redefine how millions of people shop online
