Job description

We are looking for a Senior Technical Lead to join a founder-led business group and help build a range of internal and commercial software products.

This role will involve leading the development of new SaaS-style platforms, data-driven tools, dashboards, workflow systems, and AI-enabled automation products. You will also help develop tools for our established businesses, including reporting dashboards, operational systems, and automated workflows/agents that improve efficiency and decision-making.

This is not a standard developer role. We want someone who can take ideas and business goals and turn them into practical, scalable products. You will play a key role in shaping architecture, systems, development standards, and the overall technical direction, while working closely with the founder and a second developer.

Key Responsibilities

  • Lead the technical design and architecture of new internal and commercial software products
  • Translate business ideas into structured development plans and phased deliverables
  • Define the stack, coding standards, architecture, and development approach
  • Build core systems across frontend, backend, database, and infrastructure
  • Develop dashboards, workflow tools, internal systems, and AI-enabled process automation
  • Help create reporting and operational tools for established businesses within the group
  • Manage the codebase, deployment process, environments, and release structure
  • Review and oversee the work of a second developer
  • Ensure products are secure, scalable, maintainable, and well structured
  • Use AI-assisted development tools effectively to improve delivery speed where appropriate

Requirements

  • Strong experience as a Senior Full-Stack Developer, Technical Lead, or similar senior hands-on role
  • Proven track record building software products, internal systems, or tools from scratch
  • Strong knowledge of frontend, backend, databases, cloud deployment, and system architecture
  • Experience with dashboards, portals, workflow systems, admin tools, or automation platforms
  • Comfortable making technical decisions and taking ownership of delivery
  • Able to work directly with a founder and convert high-level ideas into practical solutions
  • Strong communication skills and able to explain technical thinking clearly

Nice to Have

  • Experience with data platforms, ETL, reporting systems, or business intelligence tools
  • Experience with AI-assisted coding tools such as Cursor, Copilot, Claude, ChatGPT, or similar
  • Experience with workflow automation, internal tools, or agent-based systems
  • Experience in a founder-led or fast-moving business environment
  • Experience developing multi-user SaaS products or internal operational platforms

What We're Looking For

We want someone who is:

  • commercially minded
  • practical and delivery-focused
  • comfortable with ownership
  • fast, but sensible
  • good at turning ideas into systems
  • able to lead technical execution without needing heavy supervision
