The most forward-thinking marketers choose StackAdapt to orchestrate high-impact campaigns across programmatic advertising and marketing channels.

Engineering at StackAdapt: As an Engineer at StackAdapt, you will be directly involved in the development of our advertising platform, producing production-level code that will have a direct impact on the success of our product. You will work with large data sets and have exposure to modern tech stacks around GoLang, Ruby on Rails, React, GraphQL and more. StackAdapt’s engineering organization believes in working collaboratively and cross-functionally. You will get the opportunity to work in a diverse and flexible culture with dedicated career paths to help you succeed.

We're seeking a Full Stack Engineer to help lead our growing full-stack engineering team. The digital advertising industry is riddled with interesting challenges as we continue to scale out our platform with a fast-growing list of customers.

We are currently hiring for the following teams:

Creatives: The Creatives Team at StackAdapt is on a mission to build a one-stop-shop solution for advertisers' creative production and management needs. We're developing a comprehensive in-house tool that enables clients to create, enhance, preview, store, and manage CTV, video, audio, and DOOH ads at scale—whether using ready-made templates or building from scratch. By delivering a robust, full-featured in-house solution, we aim to reduce reliance on costly third-party creative providers and empower advertisers to move faster and more efficiently.
Developer Ecosystem: The Developer Ecosystem team enables software builders to leverage StackAdapt’s proprietary platform through APIs and MCPs. We maintain the GraphQL Public API and peripheral services, the MCP servers and tools which power our AI system (Ivy), as well as external customers’ agents. We are at the forefront of innovation in the engineering department, working cross-functionally with Data Science, Business Intelligence, and various teams to build powerful AI and automation solutions.
Delta Force: The Delta Force team is a specialized, cross-functional squad of highly skilled engineers deployed to tackle high-impact “quick wins” and quality-of-life improvements across the platform. Trained in multiple product domains and technical areas, this team operates with speed, precision, and autonomy to eliminate friction points, address user pain, and accelerate value delivery where it’s most needed.
Integrations: The Integrations team works closely with our strategic partnerships team to build native app integrations on external platforms like Shopify and Snowflake, with a heavy emphasis on integrating data into our customer data platform (CDP).
Billing: The Billing team builds the infrastructure that powers customer billing, invoicing, tax integrations, payment workflows, and cost data across StackAdapt. Candidates will work on complex billing systems, payment gateway integrations, invoicing modernization, direct mail and email billing, and financial workflow automation.
Data Hub: The Data Hub team is building a platform that helps brands organize audiences, understand customer journeys, and connect programmatic advertising with marketing technology. Candidates will work on high-visibility initiatives like predictive account scoring, customer retention analytics, external data imports, identity workflows, and vertical audience expansion.
