What’s in it for you?
- Ownership: Take ideas from concept through to production, owning features across design, development, deployment and iteration.
- Influence: Work directly with the founder and help shape the product, architecture and engineering culture.
- Product: Turn a powerful but technically configured AdTech platform into an intuitive, AI-assisted, self-service product.
- Scale: Build on infrastructure processing billions of advertising requests every day.
- AI-native engineering: Use tools such as Claude Code as a genuine part of the development process, not as an occasional add-on.
- Equity: Share in the upside of an early-stage company entering its next phase of growth.
The Opportunity:
You’ll be joining a growing AdTech company helping advertisers connect with publishers across Connected TV and Digital Out-of-Home advertising. Today, parts of the platform are configured using raw JSON. The company wants to develop a more intuitive, AI-assisted and self-service experience that allows customers to configure the platform, manage integrations and understand their reporting more easily.
As Founding Engineer, you’ll take a leading role in making that happen. This is a senior individual-contributor position rather than a people-management role. You’ll work directly with the founder, collaborate with an experienced engineering team and have autonomy over how products and features are designed and delivered.
The Role:
- You’ll own meaningful areas of the product from end to end; understanding the problem, designing the solution, shipping it into production and improving it based on real customer feedback.
- You’ll help build the configuration and reporting experiences used by publishers, introduce
- AI-assisted and self-service functionality, and extend the platform’s integrations with demand and supply partners.
- You’ll also have direct exposure to customers. That could involve understanding how they use the platform, supporting a technical integration or translating a recurring customer problem into a better product decision.
- Beyond the code itself, you’ll help establish the technical standards and working practices of growing Dublin engineering team. The company is deliberately building an AI-native engineering culture, so agentic development tools such as Claude Code will be central to how you work.
You’ll be responsible for:
- Owning features from initial idea through to production and ongoing iteration.
- Turning product direction into reliable software used by real customers.
- Developing the platform’s configuration, reporting and self-service experiences.
- Building AI-assisted workflows that simplify technically complex processes.
- Extending integrations with advertising demand and supply partners.
- Working directly with customers and publishers on product and integration challenges.
- Contributing to architecture and wider technical decisions.
- Helping establish engineering standards and culture as the Dublin team grows.
- Championing AI-assisted and agentic development practices.
You’ll be a good fit if you:

- Have a strong track record of shipping production software.
- Enjoy owning problems rather than working from fully defined tickets.
- Think about why a feature is being built and how it affects the person using it.
- Can begin with a clear problem and an incomplete specification.
- Are comfortable making technical decisions and explaining the reasoning behind them.
- Understand the considerations involved in high-throughput, low-latency systems.
- Already use AI coding tools seriously and can demonstrate how they improve your development process.
- Want to remain hands-on while having genuine influence over product and technical
- direction.
Experience in an early-stage startup or with distributed, high-volume systems, AdTech knowledge, including programmatic advertising, RTB, OpenRTB, Prebid or VAST, is a bonus,
