Job Description

Who are Picnic & what do we do?

Picnic's mission is to drive a higher quality ad-funded internet. Today, a large proportion of digital advertising is ineffective, intrusive and poorly optimised. Picnic builds technology that helps brands make better decisions about where and how their advertising is shown, improving outcomes for users, advertisers, and publishers alike.


We're a fast growing, founder-led startup. Over the last couple of years, we've built a strong platform foundation and developed clear conviction around our product direction. We're now entering a new stage where execution, reliability and scale matter as much as innovation. To support this next phase, we're looking for our first Head of Engineering.

Requirements

What will you be doing as Head of Engineering?

As Head of Engineering, you'll report to the Chief Product & Technology Officer and take end-to-end ownership of engineering execution, playing a central role in how Picnic scales technically and organisationally.

You will:

Own delivery of the engineering roadmap, taking complex decisioning and optimisation capabilities from prototype through to reliable, scalable production systems Provide technical leadership across platform infrastructure, data pipelines, applied modelling, real-time services, and external APIs Act as architectural steward of the platform, ensuring consistency, scalability, reliability, and cost efficiency as complexity increases Build and evolve engineering practices around system design, DevOps, observability, automation, and operating production systems at scale Lead, coach, and develop the engineering team, establishing clear standards, progression paths, and a strong engineering culture Lead the platform's evolution to serve external customers and partners, with clear guarantees around reliability, data freshness, versioning, and service expectations

This is a

hands-on leadership role

. You'll be close to the systems and technical decisions, while also setting direction and enabling the team to move faster and more safely.

Who are we looking for?

We're looking for an experienced, pragmatic engineering leader who has operated at a senior level in a startup or scale-up environment and is excited by the opportunity to take broad ownership of engineering execution and scale a team and platform end to end.

You will:

Have led or managed engineers in a start-up or scale-up environment Have strong hands-on experience with cloud architecture, within AWS Have experience working across product engineering, data systems, and platform infrastructure Have built and operated production systems with high requirements around reliability, performance, and cost control Be able to balance short-term delivery pressure with long-term architectural health Be comfortable operating in an experiment-driven, discovery-focused environment, and know how to transition from exploration to production Be an effective people leader, or actively looking to grow into a broader leadership role Be familiar with machine learning concepts and the infrastructure required to deploy and operate models in production Communicate clearly with both technical and non-technical stakeholders Be excited by the opportunity to shape Picnic's engineering function and platform from the ground up

Experience in advertising technology is a

bonus

, but

not required.
