InsurX is reinventing how complex commercial insurance is traded. They've grown from $20m to $70m GWP in two years and are targeting $200m this year. To support that scale, they're hiring a Head of Engineering to lead the next evolution of their platform. This is a chance to build powerful systems that automate complexity, drive real outcomes, and scale into the billions. You’ll set the technical direction, lead the evolution of their platform, and grow a lean, impact-driven team in one of the most valuable and under-innovated markets in the world.

You’ll be responsible for:

• Setting the technical direction of their platform, driving architectural decisions that enable performance, scalability, and reliability as they scale to $1bn+ in traded gross market value.

• Leading and growing the engineering team while embedding a culture of autonomy, ownership, and accountability. Building a team that thrives in a fast-paced, cross-functional environment, values clean, observable, and testable code, and protects time for foundational work such as refactoring and reducing technical debt.

• Staying close to the code, reviewing architecture and design, and contributing where needed : especially in critical or high-leverage areas.

• Establishing engineering excellence, with clear principles around reliability, security, observability, cloud infrastructure and cost-ePectiveness.

How they build

They believe in efficient, scalable engineering. That means automating what they can, iterating fast, and building just enough process to stay aligned, not to slow things down. They use modern tooling and believe engineers should use the best available tech (including AI) to accelerate development, improve quality, and reduce toil.

Their engineering culture reflects their company values: Own the outcome, Wow our customers, and Always be better. That means taking full responsibility for what we ship, building with the customer in mind (even when they don’t interact with their tech), and holding themselves to high standards, not just in what they build, but how they build it.

They also Win together. This is a cross-functional team sport, not a solo game. You’ll work closely with Product, Data, and Ops, and help build a culture of open feedback, clarity, and shared wins.

And they Lead with data: their best ideas come from evidence, not opinions. They test, learn, and use metrics to prioritise what matters.

About You

• You’re an experienced engineering leader who has successfully scaled software teams and systems in a startup or high-growth scale up in a regulated environment where trust, data integrity and uptime aren’t optional, they are contractual.

• You’ve spent 3+ years in Engineering Management roles (managing multiple teams or a growing team), and 3+ years as a hands-on Tech Lead, ideally in a venture-backed Series A+ company.

• You have experience hiring, mentoring, and developing engineers, as well as shaping an inclusive and high-trust culture.

• You’re comfortable making and guiding architectural decisions and believe in balancing technical rigour with pragmatic delivery.

• You still enjoy writing code when it matters. You’re not here to manage process, you’re here to build something that lasts.

• You’ve built or rebuilt platforms before and know the diPerence between scaling a prototype and scaling a product.

• You love working cross-functionally but want to be the one holding the technical standard, not just translating specs.

• You have deep experience with at least one major programming language (Python, C#, Java, etc.): they currently use C#/.NET for their core platform and Python for their data platform and are simplifying this stack as they scale.

• You understand what it means to operate in a regulated environment, and have built secure, reliable, and cloud-native systems, ideally on Azure.

They're not just building a team, they're building an engineering culture that values thoughtful design, automation, and results. You’ll shape how they use AI, automation, and great code to move faster than their market, scale smarter, and out-execute incumbents. This is your chance to architect the kind of platform others will be trying to replicate years from now.
