Software Engineer - Frontend

Hey, we’re KonstructIQ

We’re a seasoned founding team on our next adventure and now we’re going even bigger. Our mission? To put AI at the heart of residential construction, helping general contractors win more bids and slash manual work. From AI-powered estimating to frictionless payments, we’re building the next-gen AI construction + financial platform.

What you’ll be doing

You will collaborate closely with a small, focused team to design, develop, and deliver features that improve how contractors operate and get paid. We prioritize speed, maintainable code, and efficient solutions. We're looking for engineers who can take ambiguous concepts and transform them into fully functional, production-ready features.

You will

• Build and maintain core product features across frontend (React, NextJS, mobile)
• Collaborate directly with engineering, design, product, and sales to create seamless experiences for our customers.
• Write code with AI that balances speed with quality - we ship fast, but we also build for scale.
• Help shape our tech stack, architecture, and product direction.
• Jump into everything from UI tweaks to database queries - full stack.
• Design and ship AI-assisted product features using LLMs and tool/function calling, embedded directly into estimating, document processing, and financial workflows.
• Build and operate reliable AI workflows and lightweight agents that combine model outputs, external tools, and deterministic business logic to produce accurate, auditable results.

What we value

We’re not just hiring for skills; we’re hiring for mindset. We value people who:

• Act like an owner: you don’t wait to be told, you take responsibility, move with urgency, and care deeply about outcomes.
• Strive for excellence: whether it’s polishing a UI interaction or improving an AI-assisted workflow, you aim to make our users love us.
• Communicate openly and honestly: ideas over ego, feedback that helps, and listening to understand.
• Lead with data: measure what matters, make informed choices, and focus on high-impact work.
• Succeed in work and life: we push hard but respect boundaries, encourage time off, and celebrate wins together.

What you bring to the table

• 3–7 years of professional software development experience.
• Strong frontend development skills with React and NextJS, with working knowledge of backend technologies and APIs.
• Experience with mobile development (native or cross-platform frameworks like Capacitor or React Native).
• Solid understanding of web security principles and performance optimization best practices.
• Strong understanding of agile development practices and working in fast-moving startup environments.
• Love working in early-stage chaos — priorities change, solutions evolve, and that energizes you.
• Can take a vague problem, break it down, and deliver something customers love.
• Hands-on experience building production AI workflows involving tool/function calling or agent-like orchestration, including prompt design, context selection, and structured outputs.
• Strong judgment in designing safe, observable, human-in-the-loop AI systems, with an understanding of reliability, failure modes, and when AI is (or isn’t) the right solution.

Why you’ll love working here

• Massive impact: your work will shape the core product and be in front of customers fast.
• AI-first approach: we’re not bolting AI on; it’s baked into the product from day one.
• A stake in future success: competitive salary, meaningful equity.
• If you want to solve hard problems, work with people who care, and help bring AI into one of the largest, least-digitized industries in the world, we’d love to talk.
