About Kernel
Kernel gives enterprise RevOps teams confidence in their CRM data. We’ve raised a $14M Series A from top VCs and operators at Plaid, OpenAI, Slack and others to build the AI-native alternative to Dun & Bradstreet's entity and hierarchy data. RevOps teams at Gong, Navan, Zip, Remote and GoCardless use Kernel to clean, enrich and complete their CRM data at enterprise scale, eliminating duplicates, fixing hierarchies and restoring trust in the foundation that powers forecasting, territory planning and AI initiatives. Our platform combines entity-level intelligence with mass-action tooling to give RevOps teams the data quality and control needed to plan confidently and deploy AI successfully.
The Role
You are a T-shaped full stack engineer with a spike in backend engineering. You will work with product and engineering on the product overall and support our infrastructure so we can scale efficiently. You do not need to be a DevOps wizard, but experience with AWS and Kubernetes is helpful. You are adaptable, take initiative and enjoy contributing at pace. The team is lean, the environment is low-structure and clear communication matters. You will own our back-end infrastructure from AWS to our workflow automations in n8n and help us scale from $1 M to $10 M ARR. We are still early in building our infrastructure, so you will play a key role in shaping what we build and how we build it.
What You’ll Be Doing
- Owning and scaling Kernel's back-end infrastructure (AWS, NodeJS, Postgres, n8n)
- Designing systems that process millions of accounts, terabytes of data and thousands of parallel executions
- Building reliable, scalable data pipelines and services for enterprise customers
- Rapidly shipping features to users and to our internal team
- Continuously evaluating code, infrastructure and processes to find improvements
- Automating manual processes to increase speed and reliability
- Sharing feedback on roadmap direction and ideas on bets to place and potential solutions
More specifically you will be:
- Ensuring a world-class, scalable back-end infrastructure
- Working daily with the team to move us toward our next goal
- Implementing mass-action workflows that clean, enrich and complete CRM data
- Establishing robust monitoring, observability and reliability practices
- Partnering with product and solutions engineering to translate business logic into safe mass actions in customer CRMs
What You Bring
- 6+ years of software engineering experience
- Experience in an early-stage startup or small, fast-moving team
- A well-rounded engineering toolkit and strong backend depth
- Ability to work independently and autonomously with clear communication
- Ability to operate in a small team with shifting priorities
- Some experience with Kubernetes
- Experience working with large volumes of data
It is a plus if you also have:
- LLM experience such as building RAG models, prompt engineering and familiarity with major foundation models
- Some front-end experience
This role may not be for you if you:
- Need lots of structure
- Will only ship pixel-perfect results before releasing
- Need a fully fleshed-out spec to code
- Are heavily indexed on DevOps and have spent less time on software engineering
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)
- Do not enjoy the intensity of an early-stage startup
- Have side hustles or other projects
- Want to manage a team
What We Offer
We will do our best to offer you a ride of a lifetime. It will not be easy, but it will be thrilling.
- Salary: £120,000 - £200,000 + equity
- 24 days holiday per year + bank holidays
