ABOUT:
GAIN is a creative-led, insight-driven company that blends data, tech and creativity. We believe the best ideas emerge where intelligence and creativity unite, where insight sparks imagination, and where innovation turns possibility into progress. We are explorers of new frontiers, shaping bold strategies that move people, brands, and businesses forward. Individually and together, our specialist teams provide the vision, data, and confidence brands and organisations need to make braver, more impactful decisions.
Today as GAIN, we work as a united force, using data to fuel creativity, and technology to unlock new possibilities. As imagineers we don’t just embrace innovation – we engineer it, transforming information into action, and ideas into breakthroughs. This is where rebel thinking, smart technology, and data-driven creativity shape the future. Through our five specialist teams, Creative Studio, Conversion, Customer Science, Experience and Performance. Individually, and together, we work to fuel growth and deliver measurable impact.
THE ROLE:
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. 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 prototypes. That means thinking through reliability, cost, edge cases, and UX from day one.
- Shipping end‑to‑end product features (UI + API + data + integrations)
- Building LLM-powered workflows that are reliable, measurable, and user-friendly
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. We’re looking for engineers who can design practical solutions—not just implement specs.
What we offer
- Real ownership: ship features that matter, work on interesting problems of our time
- Mentorship + strong engineering culture: thoughtful code reviews, pairing when useful, support on hard problems (AI, systems, product), will help you become a 10x engineer
- Fully remote + quarterly meet-ups: work from anywhere, then meet a few times a year to plan, build, and bond
Requirements
We’re looking for a software engineer, a builder who ships. You’ll likely be a fit if:
- Excited about building with AI, not just using it, but making it work reliably in real products
- Strong fundamentals: systems, APIs, databases, how data flows
- Comfortable in TypeScript/JavaScript or Python
- You’ve shipped modern web products (UI + API + data)
- 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.
HOW YOU’LL WORK:
- Constant curiosity: You can think critically and understand the data, knowing where you need to take action. You’re analytical with the ability to investigate and resolve
- Pushing boundaries: You’ll make the most efficient use of technology, suggesting process improvements
- The power of our imagination: You’re a problem solver who goes the extra mile. You’ll know the best approach to take with clients to get results.
- Making it happen: You’re proactive and you know you can make a difference. You use your sound judgement when making decisions and you take responsibility for your decisions and actions.
- Putting people first: You’ll build effective relationships with people, internally and externally, understanding both business and client needs.
