• Collaborate closely with users and cross-functional teams
• Use AI tools (LLMs, copilots, agents) to improve developer experience and product capabilities
• Prototype fast, iterate often, and contribute to product strategy

• Strong software engineering fundamentals and sound architectural judgment
• Experience delivering user-ready, maintainable codebases
• Curiosity about users, not just code - you think like a product person

• Comfort working in product-led, collaborative environments
• AI literacy - confident using and adapting modern AI tools

• A globally impactful product with a clear mission: making the web safer
• A culture of openness, autonomy, and radical candour
• Real ownership and influence in what gets built
• Excellent rewards: share options, private medical, 8% employer pension, income protection, 25 days holiday + BH
• Flexible hours and a genuinely healthy work-life balance
• Regular social events, summer/winter parties, and a down-to-earth, supportive team

If you're a thoughtful engineer who values impact over output, and you want to do the best work of your career in a high-trust, high-care environment - we'd love to hear from you.
