Summary
Lead the evolution of a product-facing web experience from a lean server-rendered architecture to a modern React application. You will own frontend delivery end to end, build intuitive AI-assisted workflows, and work closely with designers and backend engineers. Candidates should have 5+ years of production web experience, strong browser fundamentals, React expertise, and a track record of shipping in ambiguous environments.
Highlights
High-ownership frontend role leading a major migration to React, shaping human-AI interaction patterns, and delivering polished, accessible, high-performance workflows in close partnership with design and backend teams.

About the Role
You will own the interface where clients work with their Virtual Bid Assistants, from onboarding through daily workflow.
Today, the product is built with a server-rendered HTMX and Flask approach: fast, lean, and tightly coupled to real product logic rather than a heavy single-page app.
The team is splitting its internal and external portals: the current app becomes the internal tool (likely staying on HTMX, which is backend-friendly), while the external experience is being redesigned in React.
A key part of this role is spearheading that migration.
The external redesign is also a shift in kind, not just stack: it is moving from a traditional software interface toward a human-plus-AI co-working workspace (think a Notion- or Cowork-style environment, but for glazing estimators) where users come in and actually finish the task, not just view data.
An engineer who is excited about human-AI interaction and has opinions about how it should work will do especially well.
This is an engineering role, not a design role; the team already has a designer, and this person owns the frontend build.
What You'll Own
The end-to-end experience Virtual Bid Assistants use to do their best work, from onboarding through daily workflowInteraction patterns that surface what the AI is doing and keep skilled estimators in controlResponsive, performant interfaces built on HTMX, Flask templates, and modern CSS/JS, and spearheading the external move to ReactClose partnership with the designer and backend engineers to turn complex estimating workflows into something that feels simplePerformance, accessibility, and polish, because details close deals
Requirements
Must-Have
5+ years building production, product-facing web applicationsStrong HTML, CSS, and JavaScript fundamentals: you understand the browser, not just a frameworkReact proficiency, with the ability to spearhead a migration from server-rendered HTMX to ReactA 0-to-1 track record: you thrive in ambiguity and own features end to end, shipping real product to real users fastAI-Native Builder: deep, demonstrated experience using AI to build, ship, and accelerate work; you can take an ambiguous problem and ship a working solutionAble to interact effectively with a Python backend (not as a backend engineer, but fluent enough to be effective on the frontend)
Nice-to-Have
HTMX or server-rendered / hypermedia experience, or genuine eagerness to work this wayPython and Flask comfort for full-stack feature workExperience designing AI-first or agentic AI products, and an opinion on human-AI interactionExperience simplifying complex workflows in a B2B settingGrowth from IC to team lead, or early-to-late-stage scaling experience (helpful, not required)AEC, glazing, or construction industry exposureVeteran or prior-service background (the founder is a Marine Corps Ground Intelligence Officer)
