Senior Software Engineer

About AiSentr AiSentr is a growing SaaS startup helping businesses unlock the power of AI without in-house AI teams. Our platform combines data ingestion, search, and LLM-driven learning into AI agents that work with a company’s internal knowledge to drive genuine customer value. We are remote-first, growing revenue and gaining customers fast in a very exciting space.

The Role We are looking for a Senior Full Stack Engineer to take a key role in scaling our product beyond MVP. This role is roughly 60 percent hands-on coding and 40 percent technical leadership, mentoring, and decision-making. You will work across the stack, lead initiatives, and help us balance delivery speed with long-term technical quality as we grow.

What You’ll Do Lead technical initiatives from design to delivery

Build and maintain features using NestJS and TypeScript, with occasional Python for data processing

Develop scalable APIs and maintain our Azure SQL-based relational data layer

Deliver high-quality, performant UI features in React / Next.js on Vercel

Collaborate with product and design to shape features end-to-end

Mentor engineers, set coding standards, and contribute to best practices

What We’re Looking For 10+ years of experience building and scaling SaaS products in a commercial setting

Strong JavaScript / TypeScript skills with deep knowledge of at least one backend framework (NestJS preferred) and one frontend framework (Next.js preferred)

Solid experience with relational databases and API design for scale

Experience of when to make architectural trade-offs in a fast-moving startup environment

Proven track record of leading technical initiatives and mentoring other engineers

Experience with cloud deployments (Azure preferred, Kubernetes and Docker useful)

Familiarity with AI / ML concepts is a plus, but strong SaaS engineering skills matter most

Why Join Us Be one of the most senior engineers in a small, high-calibre team

Have real influence on technical direction while still writing code daily

Work on a product with clear customer demand in a stable, growing business

Learn from (and teach) a team of genuinely experienced technology product builders

Fully remote with a culture of ownership, autonomy, and trust

If you want to work at the point where impactful engineering meets a real product and real customers, we’d like to hear from you.
