Role Overview

We are seeking a Senior Full-Stack Engineer (.NET / AI) to help build and scale the next generation of applications for one of our growing enterprise clients.

This is a senior-level engineering role with a strong backend focus, combining modern full-stack development with AI-powered application development. You will be responsible for architecting and building scalable systems, establishing development standards, integrating Generative AI solutions into production environments, and driving technical decisions across multiple initiatives.

The role is ideal for someone who thrives in ambiguous environments, enjoys building systems from scratch, and can operate as a highly autonomous technical leader while collaborating closely with Product, Design, and Engineering stakeholders.

Exceptional Leadership

As an Andelan, you’ll serve as a role model for the rest of the company. Think about the feedback your peers typically give you — if it usually sounds like the below, we want to hear from you.

Low ego, low drama, servant leader: You share credit, take blame. You like being wrong because it means someone else had an even better idea.

One team mentality: You break silos across teams. You put the company and mission first above your team alone.

Great listener, hungry for feedback: You’re always seeking to improve — our product, our business, yourself. You solicit diverse opinions and deeply listen.

Owner, not renter: You see a problem, you fix it or find someone who will. The buck stops with you.

Player-coach: You fly high and low. You understand the strategy while staying close to the details that matter. You roll up your sleeves, stay hands-on, and empower others without micromanaging.

Business problem solver: You’re not just a functional expert; you approach your work through the lens of solving business problems.
