About the Role As a Founding Engineer, you’ll be the first in-house engineering hire, owning the platform across frontend, backend and infrastructure. You’ll scale and evolve the existing AI-native Professional Services Automation platform while continuing to deliver customer-facing features. This is a senior/staff-level IC role with significant ownership and autonomy, with scope to grow as the company scales. Responsibilities Own the product end-to-end as a solo generalist, building, shipping and deploying across frontend, backend and infrastructure without a supporting team. Keep the live platform healthy, including handling incidents and defects and managing safe releases and rollback. Use AI/agentic coding tools to increase personal output while independently verifying correctness, security and robustness rather than trusting AI-generated output blindly. Lead the platform towards ISO 27001 and SOC 2 readiness by April 2027, translating external compliance requirements into concrete engineering controls; prior certification experience is not required. Make the AI assistant and orchestration features reliable, measurable and safe. Decide what to preserve, isolate, improve or replace in the current platform based on customer risk and commercial value, without undertaking an unnecessary rebuild. Move fluidly across frontend and backend as a true full-stack generalist, with no fixed frontend/backend split. Harden, scale and evolve the existing product, including delivery intelligence, AI assistant, SOW ingestion, project/resource/commercial management and a beta orchestration layer, while continuing to ship customer-facing improvements. Work solo end-to-end as the company's hands-on technical owner, with the potential to help decide on and shape the first supporting engineering hire once funding closes. Work effectively with high ambiguity, evolving scope and close, direct collaboration with both technical and non-technical founders. Requirements 5+ years of professional software engineering experience, ideally including early-stage startup or high-ownership experience. 5+ years of senior-level full-stack engineering experience across a React/TypeScript frontend and Node/Postgres-style backend, or a strong modern JavaScript/TypeScript full-stack equivalent such as Next.js or Vue/Nuxt, with proven end-to-end ownership. 4+ years of senior-level experience with solo ownership of cloud deployment, releases and CI/CD, or a proven record of shipping and operating production infrastructure without a dedicated DevOps/platform team. 3+ years of senior-level experience with Postgres/Supabase or equivalent, including row-level security and edge functions. Deep relational database experience with another Postgres-based backend, Firebase or PlanetScale is also acceptable. 1–2+ years of senior-level experience using AI-assisted/agentic coding tools such as Cursor, Claude Code or Copilot to ship production software, or demonstrable heavy and disciplined use of LLMs within a professional development workflow. Have a clear method for checking AI-generated output rather than trusting it blindly. Be comfortable operating as a senior/staff-level individual contributor generalist and owning a product or platform end-to-end solo or near-solo; formal project-leadership titles are not required. Nice to Have 1–2+ years of LLM application engineering experience covering prompt design, evaluation, grounding and orchestration/agent safety, or evidence of fast, rigorous learning in a new technical domain. 2+ years of security fundamentals covering multi-tenant access control, secrets management and authentication/OAuth, or a security-conscious engineering track record without a formal security title. Experience translating ISO 27001/SOC 2 requirements into engineering practice. No prior certification experience is required, but you must be able to research and implement compliance requirements independently ahead of the April 2027 target. 2+ years of startup/founding engineer or small-team, high-ownership experience, or a track record of shipping solo or near-solo end-to-end without a supporting team. 1+ year of rapid-prototype/AI-generated codebase remediation experience, such as with Lovable, v0 or Bolt-originated codebases, or experience stabilising and hardening fast-built code of any origin. 1+ year of Stripe billing/payments API integration experience, or experience with another payments or metering API integration.
