Role Description

The Technical Co-Founder (
Pre-Rev
) will play an integral role in developing and advancing HHC’s generative AI-based software solutions for the construction industry. Responsibilities include overseeing the technical roadmap, building and maintaining scalable infrastructure, and managing the end-to-end software development lifecycle. Collaboration with other team members on strategic planning, product design, and implementation will be essential. This is a full-time remote role, perfect for someone passionate about merging technology with innovative solutions in the construction sector.

Mission Alignment

We believe in the power of human-centric AI for field-first construction teams. That means building AI as a mentor and coach, not a replacement. Our ideal co-founder shares this philosophy. You should resonate with our “Mentor” brand ethos – we’re all about guiding and upskilling the blue‑coloured professionals who actually build the world. Hard Hat Coach .ai focuses on blue‑coloured‑first AI adoption, delivering practical, field‑ready AI coaching & tools that helps superintendents, project managers, and foremen work faster, safer, and more effectively.

In short, we build tools that the folks on the job site trust and love to use – and you should be excited about that mission.

Technical Requirements

We need a full‑stack AI engineer who can design and lead development of our platform. Key requirements include:

• AI/ML Engineering & LLMs
  :
  Strong experience in machine learning and building products with large language models (LLM‑based tooling). You’ve possibly worked with GPT or similar, and you know how to fine‑tune or prompt these models effectively.
• Full‑Stack Development
  :
  Ability to architect and code across the stack (front‑end, back‑end, database). You should be comfortable wearing multiple hats in early development.
• Retrieval‑Augmented Generation (RAG):
  Familiarity with RAG techniques (using external knowledge bases to make LLM responses more factual). Our AI will likely need to pull in project data, manuals, or regulations on the fly – you should know how to implement or utilize RAG pipelines.
• Data Security & Compliance
  :
  Knowledge of implementing SOC 2 controls and GDPR compliance. Our target customers operate in enterprise environments, so security and privacy can’t be an afterthought.
• Architectural Best Practices
  :
  Experience (or strong interest) in multi‑tenant SaaS architecture. You should understand data security, role‑based access control (RBAC), and how to design systems that scale for many enterprise clients while keeping each client’s data isolated and safe.
• Construction Tech Integration
  :
  Bonus if you have familiarity with construction industry tech – e.g. integrating with BIM (Building Information Modeling) tools, or APIs of construction management platforms like Procore or ACC (Autodesk Construction Cloud). Even if you haven’t, being eager to dive into these domains is important.
• Prompt Engineering
  :
  You should be comfortable with prompt engineering and iterating on AI behavior. Since our product will involve conversational or assistive AI for end‑users, skill in crafting and refining prompts (and maybe fine‑tuning models) is valuable.

Experience & Fit

• Industry & Domain
  :
  Experience in construction tech or related developer tools is a big plus. If you’ve built software for the field (or have family in the trades and a passion for helping them), that’s icing on the cake.
• Startup &…
