ISTARI is a strategic cybersecurity advisory company with a bold vision; to curate the defining cybersecurity ecosystem of our time, uniting enterprise, academia, government, and innovators to build collective resilience. At the heart of this mission, ISTARI helps clients achieve lasting organisational cyber resilience by convening and applying world‑class talent, expertise, and innovation through a uniquely powerful network, with ISTARI as the central orchestrator.

The Opportunity: We are seeking an entrepreneurial, AI‑native developer to join ISTARI as a contract developer and help transform how we deliver our consulting work. You will be the founding technical resource responsible for building a suite of AI‑powered internal tools that dramatically improve productivity across our Advisory practice. This is not a traditional development role. You will be expected to leverage AI coding assistants (such as Claude Code, GitHub Copilot, and similar tools) as force multipliers, enabling you to deliver at the speed and scope of a small team. You will work directly with partners and consultants to understand their pain points, translate business requirements into technical solutions, and rapidly iterate on tools that make a measurable impact. If you thrive at the intersection of cutting‑edge AI tooling and practical business problem‑solving, and you want to shape how a fast‑growing cybersecurity firm operates, this role is for you.

What You'll Do (Key Responsibilities)

  • AI‑Powered Tool Development
    • Rapid Prototyping: Design, build, and deploy internal tools that automate repetitive consulting tasks – from report generation to data analysis to client deliverable creation.
    • AI‑Assisted Development: Use AI coding tools (Claude Code, Cursor, GitHub Copilot) as your primary development methodology, demonstrating best practices for AI‑augmented software engineering.
    • Full Stack Ownership: Own the entire technical stack – from frontend interfaces to backend services to deployment infrastructure – as the sole developer.
  • Business Translation & Requirements
    • Stakeholder Engagement: Work directly with Partners, Principals, and Consultants to understand workflows, identify inefficiencies, and prioritize high‑impact automation opportunities.
    • Requirements Definition: Translate ambiguous business needs into clear technical specifications. Ask the right questions, propose solutions, and iterate quickly based on feedback.
    • User‑Centric Design: Build tools that consultants actually want to use – intuitive, reliable, and genuinely time‑saving.
  • Technical Infrastructure
    • Architecture Decisions: Make pragmatic technology choices that balance speed of delivery with maintainability and security requirements appropriate for a cybersecurity firm.
    • Security‑First Mindset: Ensure all tools meet ISTARI's security standards. We advise clients on cybersecurity – our internal tools must reflect that expertise.
    • Documentation & Handover: Maintain clear documentation so tools can be supported and extended as the team grows.
    • Stay Current: Keep pace with the rapidly evolving AI development landscape. Evaluate new tools, techniques, and models that could accelerate our capabilities.
    • Knowledge Sharing: Help upskill the broader team on AI tools and techniques. Demonstrate what's possible and help consultants incorporate AI into their own workflows.
    • Measure Impact: Track and communicate the productivity gains from tools you build, helping justify continued investment.

What You'll Bring (Candidate Profile)

  • Experience & Target Background
    • We are looking for developers who have embraced AI‑assisted development as a core part of their workflow.
    • Target Backgrounds:
    • AI‑Native Developers: Engineers who have integrated Claude Code, Cursor, or similar AI coding assistants into their daily workflow and can demonstrate significant productivity gains.
    • Full Stack Generalists: Developers comfortable across the stack – web frontends, APIs, databases, cloud infrastructure – who can ship complete solutions independently.
    • Startup/Scale‑up Experience: Engineers who have worked in resource‑constrained environments where they owned entire product areas and delivered quickly with minimal oversight.
    • Proven Delivery Track Record: Demonstrated ability to ship working software quickly. We value pragmatic delivery over perfect architecture.
    • Business Acumen: Experience working directly with non‑technical stakeholders, gathering requirements, and translating them into technical solutions.
  • Core Competencies
    • AI Tool Fluency: Expert‑level proficiency with AI coding assistants. Candidates should be prepared to pair‑program using AI tools during the interview process and provide portfolio examples of work built with AI assistance.
    • Technical Breadth: Comfortable with modern web technologies (e.g. React, Node.js, Python, or equivalent), cloud platforms (AWS, GCP, or Azure), and database technologies. Not necessarily expert in all, but capable of learning quickly and building effectively. We value adaptability over specific stack expertise.
    • Communication Skills: Able to explain technical concepts to non‑technical stakeholders and ask clarifying questions that get to the heart of business problems.
    • Self‑Direction: Comfortable working autonomously, managing your own priorities, and proactively identifying opportunities to add value.
    • Security Awareness: Understanding of secure development practices. You'll be building tools for a cybersecurity company – security cannot be an afterthought.
  • Technical Requirements

    • Required: 3+ years of professional software development experience. Demonstrated experience with AI‑assisted development tools.
    • Preferred: Experience building internal tools or productivity applications. Familiarity with LLM APIs and prompt engineering. Background in consulting, professional services, or B2B environments.

    How We Measure Success (KPIs)

    • Delivery (Output): Number of tools shipped and actively used by the team. Speed from concept to deployed solution.
    • Impact (Outcomes): Measurable time savings for consultants using your tools. User adoption and satisfaction scores from internal stakeholders.
    • Quality (Reliability): Tool uptime and stability. Security review pass rate. New AI techniques or tools successfully integrated into workflows. Knowledge transfer and enablement of broader team.

    Duration: Initial 6‑month engagement with potential for extension

    Commitment: Full‑time equivalent (~40 hours/week)

    Location: London or fully remote. Remote candidates must have significant overlap with UK business hours (minimum 4 hours daily) and hold existing right‑to‑work as a contractor in their country of residence.

    Day Rate: £500–700/day depending on experience

    Security: No security clearance required, but candidates must be comfortable working under client confidentiality requirements typical of cybersecurity engagements. Background check may be required for certain client projects.

    If you are a builder who thrives with AI tools and wants to help shape how a growing cybersecurity firm operates, we encourage you to apply.
