Senior Fullstack Engineer (TikTok)

We're looking for a Senior Fullstack Engineer to help build and evolve Smartly's TikTok offering, enabling some of the world's largest advertisers to create, manage, automate, and optimize their TikTok campaigns at scale.

TikTok is an important part of Smartly's multi-channel advertising offering. The capabilities you build will directly shape how our customers run their advertising on the platform - from the experiences they use to create and manage campaigns to the automation, services, and integrations behind them.

If you enjoy solving complex product and engineering problems, meaningful ownership, and seeing your work have a direct impact on customers, this is a role where you'll get all three. You'll work end-to-end across the stack - from building intuitive user experiences to designing the services and integrations behind them. You'll also have the opportunity to explore how AI and automation can help us build better products and improve how we work as engineers.

You'll have real influence over both what we build and how we build it. You'll take significant product capabilities from idea to production, contribute to architectural and product decisions, and make pragmatic trade-offs between user experience, scalability, reliability, and speed.

You'll work closely with experienced engineers, product managers, and designers who enjoy solving difficult problems together and learning from each other. As a senior engineer, you'll also mentor others, share knowledge, and help us continuously improve how we build software.

Our tech stack Backend: Node.js, TypeScript

Frontend: React, TypeScript

Infrastructure: PostgreSQL, Redis, Kubernetes

Architecture: Distributed systems, event-driven services, large-scale data processing

What you'll do Own significant TikTok product capabilities end-to-end, from customer-facing experiences to the services and APIs behind them
