Software Engineer – AI Marketing Products GAIN IQ: We turn intelligence into action, building AI products that help marketing and growth teams see what matters, test what works, and scale performance that lasts.
What we’re building The way software works is changing.
AI agents are moving from demos to real workflows—tools that don’t just answer questions, but help people do their jobs better.
We’re building that for marketing.
Think about how tools like Cursor or Claude Code changed what’s possible for engineers; we’re creating the same kind of intelligence layer for marketing teams—a suite of products that help them move faster, see clearer, and make better decisions.
Our stack today includes AWS Lambda functions, API Gateway, S3, Supabase Postgres, GCP Veo for image generation, and Stripe for payments, with deep integrations into ad platforms and analytics.
We’re a small team shipping fast.
This is the stage where the right engineers can shape what this becomes.
What you’ll work on You’ll build AI‑powered features that make it into production—not prototypes.
That means thinking through reliability, cost, edge cases, and UX from day one.
Typical work looks like: Shipping end‑to‑end product features (UI + API + data + integrations) across Ares, Athena, and new products.
Designing and implementing LLM‑powered workflows that are reliable, measurable, and user‑friendly.
Working across our serverless platform: AWS Lambda, API Gateway, S3, Supabase Postgres, and event‑driven services.
Integrating external services like GCP Veo for image generation, Stripe for billing and trials, and ad platform APIs.
Owning performance, observability, and incident handling for the features you ship.
Collaborating closely with product, design, and support on acquisition, activation, purchase, and support journeys.
Creativity is part of the job.
A big part of building great AI products is creative problem solving: turning messy, ambiguous problems into simple workflows people love.
What we’re looking for We’re looking for a software engineer—a builder who ships.
You’ll likely be a fit if: You’re excited about building with AI—not just using it, but making it work reliably in real products.
You have strong fundamentals: systems, APIs, databases, and how data flows through a modern SaaS product.
You’re comfortable in TypeScript/JavaScript or Python, and have shipped modern web products (UI + API + data).
You’ve worked with cloud‑native/serverless architectures (AWS Lambda, API Gateway, S3 or similar) and relational databases like Postgres.
You’re happy integrating third‑party APIs (Stripe, AI providers, ad platforms) and dealing with all the edge cases that come with them.
You’d rather deliver something imperfect and improve it than plan forever.
AI‑native development: you use coding agents to move faster—without outsourcing judgment.
You can integrate LLM capabilities responsibly, think about failure modes, and own what you ship.
You don’t need to check every box.
If you’re strong in some areas and hungry to grow in others, we want to hear from you.
