    Description

    OpenKit
    | Remote/Hybrid | £35,000–£45,000 per annum

    About OpenKit

    OpenKit is an AI consultancy delivering bespoke solutions to government and enterprise clients. Since 2020, we have established ourselves as a trusted partner to organisations including the Department for Education, London borough councils, and clients across various private sectors. Our work includes AI-powered assessment platforms that have reduced teacher workload by 50%, as well as bespoke AI agents operating within complex business environments.

    We are recruiting a full-time developer to join our team and work alongside our founders, Ibrahim (CEO) and Reuben (CTO), in building production AI systems and automations.

    Responsibilities

    You will work directly with the founders on client projects, developing AI applications that address operational challenges for our clients. Your responsibilities will include:

    • Developing full-stack AI applications using PostgreSQL, Supabase, React, TypeScript, and Python
    • Implementing RAG systems for enterprise LLM applications
    • Designing and refining prompt chains and AI agents
    • Building and integrating internal and external APIs to connect AI systems with existing infrastructure
    • Benchmarking AI model outputs to ensure reliability and accuracy in regulated environments
    • Utilising AI coding tools to accelerate development whilst maintaining code quality

    This role will provide exposure to diverse sectors including legal, healthcare, education, and government, working on projects ranging from rapid internal prototypes to mission-critical production systems.

    Requirements

    We are seeking candidates who:

    • Have a demonstrable interest in AI development through side projects, open-source contributions, blog posts, or a GitHub portfolio showcasing AI experimentation
    • Are comfortable working across the full stack, including databases, APIs, frontends, and AI integration
    • Have experience with relational databases (PostgreSQL preferred) and API development
    • Can provide tangible evidence of engagement with AI technologies e.g. through personal projects, or participation in AI communities/hackathons.

    Desirable:

    • Experience developing custom RAG systems with vector databases or model fine-tuning
    • Familiarity with Supabase/SQL or vector databases
    • Knowledge of prompt engineering techniques (e.g., structured responses, tool use) and understanding of LLM limitations
    • Experience with AI model evaluation methodologies
    • Familiarity with automation tools such as N8N

    What We Offer

    1. Compensation:
      £35,000–£45,000, dependent on experience with yearly bonuses
    2. Professional development:
      You will work directly with two technical founders and other developers, with opportunities for rapid skill development. An annual learning budget supports courses, books, and conference attendance. We support progression towards AI specialisation, technical architecture, or team leadership.
    3. Immediate impact:
      Contribution to live client projects, building systems that improve operational efficiency for our clients.
    4. Flexible working:
      Remote-first with optional co-working in Cambridge and flexible hours.
    5. Annual leave:
      28 days incl. bank holidays

    How to Apply

    Please send your CV and a short note addressing the following:

    1. What aspects of AI development interest you most
    2. A project (personal or professional) you consider significant and why
    3. Links to your GitHub, blog, or portfolio demonstrating your work
