Founding Fullstack Engineer @Verso (backed by Hexa) - Permanent H/F

You will join Verso as a Founding Engineer to own systems end-to-end from infrastructure to product, with no strict boundaries - and help define engineering standards, observability, and the foundations of the team., * You will work on long-form, high-stakes interactions, not short prompts

• You will design systems where AI quality is as critical as system reliability
• You will operate at the intersection of AI, data, infrastructure, and product

Current stack

• Frontend: TypeScript, React, Tailwind, shadcn
• Backend: Python, FastAPI, SQLAlchemy
• Infra: Vercel, Railway, Supabase AWS
• AI: LLM orchestration, STT/TTS pipelines, eval systems (rapidly evolving)

Note: no need to necessarily master Python and Typescript, your coding agents do -

Do you have experience in TypeScript?, * You want to build production-grade AI systems on messy, real-world data - not demos

• You're comfortable owning systems end-to-end, from architecture to production
• You have experience with complex systems (real-time, data pipelines, or LLM-based products)
• You have strong intuition for trade-offs (latency, cost, quality, reliability)
• You're motivated by building an ambitious, category-defining company with long-term ownership - not just execution.

• Category-defining shift: we're not improving research workflows - we're turning consumer understanding into a continuous system
• Hard technical problems: production AI systems over rich, unstructured data (audio, video, text, structured), spanning both a B2C product (low latency, high scale, responsiveness) and a B2B platform (enterprise-grade reliability, security, and data integrity).
• Full ownership: you'll own architecture, product, and execution from day one, with direct impact on the company trajectory.
• Meaningful equity: early-stage package with strong upside, aligned with long-term value creation (next fundraise in the coming months).
• Hexa environment: operate within a top-tier startup studio, with access to talent, resources, and a strong builder ecosystem.

Verso is committed to creating a diverse environment. All qualified applicants will receive consideration for employment irrespective of gender, origin, identity, background, and sexual orientation.

We replace traditional qualitative research agencies with an AI-native platform that conducts, analyzes, and compounds consumer conversations at scale. Instead of one-off studies, companies get a continuous, structured understanding of their customers. Our ambition is to make consumer insight a real-time, always-on system embedded in every product and marketing decision. We're starting with AI-moderated interviews - but this is just the entry point. The long-term product is a system of record for consumer understanding, powered by agentic workflows. Backed by Hexa (eFounders), behind Aircall, Front, Spendesk, Yousign and 50+ others. Verso is founded by an experienced team with a strong track record in strategy, technology, and company building.
