The role
We're looking for a Senior Product Engineer (full stack) to set the technical standards for software development across client engagements. This is a hands‑on role where you'll split your time between technical leadership and writing code.
Responsibilities
- Leading technical delivery for our clients, architecting and building exceptional digital products.
- Working in cross‑functional teams, alongside other disciplines like product managers, user researchers, designers, mobile engineers and more.
- Setting engineering standards across Loomery’s community of practice, establishing best practices and technical excellence.
- Mentoring and developing others, fostering a culture of continuous learning and growth.
- Supporting business development by contributing technical expertise to sales pitches and client conversations.
- Balancing strategy with execution – one day you might design system architecture, the next debugging production issues.
- Building for the future with emerging technologies including AI, spatial computing, and next‑gen platforms.
The salary range for this role is £70,000 to £85,000.
About you
Essential experience
- Extensive engineering experience with a track record of shipping high‑quality products at scale, up and down the stack.
- Technical leadership experience – you've guided technical decisions and influenced engineering culture.
- Polyglot developer with deep expertise in at least one primary technology stack (.NET and Azure is preferred for this role).
- Product mindset – you think through customer experience and business needs first, then determine the technical solution.
- Excellent communication skills – you can explain complex technical concepts to both engineers and non‑technical stakeholders.
- Adaptability – you're comfortable working across different technologies, languages, and problem domains.
Nice to have
- Experience developing with AI/ML and emerging technologies.
- Mobile development experience (native or cross‑platform).
- Client‑facing experience in consultancy or agency environments.
- Startup or scale‑up experience in fast‑moving environments.
- Interest in spatial computing, AR/VR or other cutting‑edge tech.
Benefits
- Real impact – shape our technical direction and work with some of the UK's most innovative companies from day one.
- Transparent growth – clear progression paths, open compensation system, and regular development conversations.
- Flexibility that actually works – we support flexible hours, hybrid working, and we’ll pay to kit out your home office with whatever you need.
- Enhanced parental leave – we offer 18 weeks maternity fully paid and 6 weeks paternity fully paid for those who’ve been at Loomery longer than one year.
- Always learning – £250 annual budget for tech and gadgets plus additional grants for learning activities that align with company growth and development goals. The chance to work with cutting‑edge technology.
- Purpose‑driven – we believe in the power of technology to help people and offer big discounts to charities like Little Village. We also recognise everyone needs to do more to address the climate crisis and we offset all the carbon we use.
- Great people – we organise regular social events, and invest in building relationships. This year that’s included a 2‑day company retreat in the countryside, a talk series and picnic for Mental Health Awareness Week, and go‑karting to celebrate hitting our quarterly goals.
How we work
- Believe in the Brainweave. We believe the best ideas come from combining diverse perspectives, skills, and experiences. We encourage cross‑functionality, active listening and learning from each other. We call it The Brainweave.
- Be the highlight of your client's week. We care deeply about our clients, their goals and organisations. We go beyond delivering great products — we build strong partnerships, offer real insight and go further.
- Just F***ing Ship It (JFSI). We start by making and we learn by shipping products. Our approach is pragmatic and practical, valuing progress over perfect plans. If in doubt, just f***ing ship it.
- Wonder what's next. We are curious about what’s next in technology. We explore, tinker and try things out. Then we get cracking to use it to make a world that works better.
- Run at the hill. We look for opportunities for everyone to stretch themselves and learn rapidly in a supportive environment.
- Cut the babble. We take complex technical topics and make them easy to understand. Simple as that.
- Own the outcome. We value those who move things forward, taking responsibility to make progress and solving problems for and with others.
