Description
The opportunity
We're launching a new vertical SaaS business within Valsoft to build an AI-powered communications platform for skilled trades and home services, and we need a Founding Senior Full-Stack Developer to architect and build it from the ground up.
Skilled trades and home services businesses are experiencing unprecedented demand, yet most are losing revenue daily due to operational bottlenecks that legacy business systems can't solve. Our AI platform will autonomously manage customer calls, book appointments, and handle follow-ups, capturing lost revenue and freeing trade professionals to focus on their craft instead of their calendars.
The market is large, fragmented, and proven. Established players have demonstrated strong demand and rapid adoption, validating both willingness to pay and urgent need. As Founding Senior Full-Stack Developer, you'll architect the platform, be the first technical hire working directly with the CEO / founding team, and own the technical execution, backed by Valsoft's capital, infrastructure, and portfolio resources to move fast and win.
What You'll Be Doing
Architect and build an AI product from 0-1: prototype, MVP, and initial production release
Build cloud services on AWS with serverless and containerized components (e.g., AWS Lambda, Docker, Fargate/ECS/EKS) for scalability and resilience
Optimize performance & reliability for high-concurrency voice interactions (latency budgets, error budgets, observability)
Measure what matters: set up metrics for containment/conversion, latency and cost per successful task
Raise the bar: code reviews, design docs, and contribution to on-call with clear SLOs
Champion best practices in product development, scalability, and system design
What You Bring
Bachelor's degree in Computer Science, Engineering, or related technical discipline (or 5+ years of equivalent experience) with hands-on ML / AI systems experience
Prior experience building with LLMs, agents, or voice AI systems and strong interest in applied GenAI in real-world environments
Profound knowledge of JavaScript/TypeScript with a focus on building serverless and containerized applications
Outstanding problem-solving skills and the ability to thrive under operational pressure
AI-First mindset: Actively using AI efficiency tools to accelerate development, with an understanding of prompt engineering and agentic systems
Clear, concise communication; ability to turn ambiguous goals into stable designs
Good To Have
Experience scaling AI products in production
Previous startup or 0-1 product experience
Expertise in AWS technologies beyond the basics, such as AWS ECS, EKS, and Fargate
What You'll Own
Technical foundation: You'll build the core platform from scratch and own the codebase as it scales
Architecture decisions: You'll shape the technical stack, infrastructure, and engineering practices
Product impact: Your code will directly solve real problems for thousands of trade professionals
How To Apply
Interested? Send your resume and a brief note about why you're excited about this opportunity. We'd love to see:
Links to relevant projects (GitHub, portfolio, etc.)
Examples products you built (bonus points if they integrated existing AI models)
Anything that demonstrates your 0-1 building ability
