Requirements
- 6+ years of software or product engineering experience
- Strong experience building and scaling production systems
- Expert with frontend engineering (NextJS, React, TypeScript)
- You have a good eye for design and good at bringing complex interfaces to life
- Strong understanding of LLM application development patterns (RAG, prompt engineering, consistency testing) - either through production experience or demonstrated personal projects. If you're new to LLMs but have shipped complex production systems in other domains and are comfortable rapidly learning new technologies, we'd still love to hear from you.
- Ability to operate autonomously in a small, high-velocity team
- Excellent communication and collaboration skills
- Strong experience with modern frontend tooling or performance optimization
- It is a plus if you also have:
- Experience working on AI-driven or data-heavy products
- Backend experience (NodeJS, Postgres, TypeScript)
- Understanding of CRM data models or workflow automation
- ⚠️ This role may not be for you if you:
- Need lots of structure or long-term roadmaps
- Prefer perfect specs before building
- Focus narrowly on backend or frontend only
- ❌ This role is definitely not for you if you:
- Prefer fully remote work (this role requires at least 3 days a week in the office)
- Don't enjoy the pace of early-stage startups
- Want to manage a team rather than build
- Back-end (AWS): NodeJS, TypeScript, Postgres
- Front-end: NextJS, TypeScript, Tailwind
- Workflow automation: n8n
- We are around 30 people with 7 engineers and 1 Product Manager, including:
- Sam Houghton, Founding Engineer

- 🎫 Visas & Relocation
- We sponsor visas for exceptional candidates and provide relocation support for those moving to London.
Responsibilities
- Work as a Product Engineer in the Frontend department at Kernel Engineering team based in London.
- Engage with engineering teams to build great work ethic and drive for success within an ambitious company culture focused on generational impact.
- Collaborate closely with other engineers, designers, product managers, QA testers, UX researchers, data scientists, etc., as needed in the team's projects to ensure a cohesive and successful outcome for Kernel products or services. (This is an implied responsibility based on typical engineering roles but not explicitly stated.)
- Engage with customers directly through various channels such as phone calls, emails, live chat sessions, social media platforms like Twitter/Facebook etc., if required in the role to understand their needs and gather feedback for product improvements or new features. (This is an implied responsibility based on typical engineering roles but not explicitly stated.)
- Participate actively in team meetings including standups, retrospectives, sprint planning sessions, demos etc., as required by the role to ensure alignment with project goals and timelines. (This is an implied responsibility based on typical engineering roles but not explicitly stated.)
- Contribute ideas for product improvements or new features during team discussions if applicable in this specific job posting context. (Implied from general expectations of engineers, yet no explicit statement made it clear that the role requires such contributions.)
Benefits
- £110K – £170K • Offers Equity
- Kernel provides enterprise RevOps teams with AI-powered company data for their CRMs. We raised $14M in Series A funding from top VCs and operators at Plaid, OpenAI, and Slack to build an AI-native alternative to Dun & Bradstreet's entity and hierarchy data.
- RevOps teams at Navan, Gong, Mistral, and AlphaSense use Kernel to run their organizations.
- At Kernel, we process 7B+ tokens a day and run 1.8M+ agents daily, all on an architecture that's intentionally simple: one database, one queue. It's minimalism built for massive scale (For reference, Wikipedia has 2.3B tokens in the English wikipedia). Our queue processes a daily volume on par with the entire Visa network's transactions (~365M/day). All of which has been built by a small but mighty team of engineers.
- We will do our best to offer you a ride of a lifetime. It will not be easy, but it will be thrilling.
