Role
Who you are
- 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
- 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
Desirable
- LLM experience such as building RAG models, prompt engineering and familiarity with major foundation models
- Some front-end experience
What the job involves
- 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
- 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
Application process
- Stage 1 – 30-minute intro call with Sandi. You will get an overview of Kernel and discuss your motivations and strengths
- Stage 2 – Take-home task (≤ 4 hours) solving a real Kernel problem
- Stage 3 – 90-minute technical interview in our London office to review your solution and understand your thinking
- Final Stage – Founders interview with Anders (CEO) and Marcus to explore values alignment
- If there is mutual fit, we move to references and offer

Our take
Company revenue and sales teams spend considerable time manually researching potential leads and customers, ascertaining if these potential clients are suffering from the problem their product is solving. Trawling through lead job descriptions and non-public financial data is a lengthy process, especially if you’re trying to infer information from them. Kernel.AI, formerly known as Momentum AI, saves revenue and sales team time with its fleet of AI Agents.
Kernel’s AI agents can be synced to Salesforce accounts to automate research into potential leads. The software maximises revenue and saves teams insurmountable time by building lists of potential customers. Growing enterprises such as GoCardless and FlatPay use Kernel to speed up their lead list.
The AI sales agents market was valued at $5.1 billion in 2024. By 2030, it’s expected to grow to $47.1 billion, indicating a lucrative space for Kernel. Launched by a founder who has already successfully launched two companies, Kernel shows plenty of promise as it builds itself up from 2023 seed funding.
