Lead Product Engineer

Help decide what gets built, lead the engineering and help the world build better. Lead Product Engineer Location: Hubexo Newcastle Hub One Trinity Gardens Working Pattern: Mon-Fri Hybrid Salary: DOE Hubexo’s software helps construction businesses find projects, share product information, write specifications and manage tenders. Your contribution will be to understand the problems customers face and turn that insight into dependable, useful software.  You’ll be part of our global product and engineering team, drawing on colleagues across Architecture, Platform Engineering, QA, AI & Data, and Security. Together, you’ll take work from customer discovery through delivery, operation and improvement. As Lead Product Engineer, you’ll work alongside a Product Manager and Product Designer to decide which customer problems to tackle and how to solve them. We build our products in-house so you’ll have genuine ownership of the technical direction of your product area and stay hands-on across front end, back end and cloud, writing and reviewing production code each week. What you’ll do Shape product decisions with Product and Design. Speak with customers, bring engineers into discovery and challenge assumptions with simpler solutions or experiments. Lead technical design and architecture while writing and reviewing production code. Build secure, scalable and accessible solutions, balancing customer value, delivery speed, quality and technical debt. Define success measures before building. Use product analytics, feature flags and staged rollouts to review results and decide what to improve next. Strengthen testing, release automation, observability and recovery. Take part in incident response and meet relevant security and compliance obligations. Coach engineers to make sound product and technical decisions. Use AI coding and agentic tools throughout delivery, setting clear standards for validating their output and sharing learning across teams. Success means measurable improvements for customers, reliable delivery and engineers increasingly able to make good decisions independently. What you’ll bring You’ll have substantial hands-on experience designing, building and scaling complex SaaS systems, including leading technical direction for a product area. We’re looking for: Strong full-stack TypeScript/JavaScript skills, with frameworks such as NestJS, React or Next.js, alongside REST or GraphQL APIs and SQL or other data stores. Experience building and operating applications on AWS or a similar cloud platform in an agile, DevOps environment. Examples of shaping what was built and measuring whether it worked, with direct customer or user involvement through discovery, research or support. Working knowledge of product analytics and experimentation, such as PostHog, feature flags and staged rollouts. Daily, considered use of AI coding and agentic tools, with a clear approach to validating their output. Experience developing other engineers and influencing without line-management authority, with clear written and verbal communication about technical trade-offs. Enterprise or regulated B2B SaaS experience, familiarity with frameworks such as SOC 2, FedRAMP or GDPR, and experience with global products or building AI features would be useful. Construction, specification or procurement knowledge would also be advantageous for you but that's desirable rather than essential. Benefits Monday to Friday. You’ll collaborate three days at our One Trinity Gardens Hub in Newcastle and two days working from home. Benefits include: 25 days’ holiday plus bank holidays, the option to buy or sell holiday, and birthday leave. Two volunteering days. Pension and life assurance.
