Senior Principal Engineer

Technical Lead / Architect, TechGrove AI Engineering Pod

You are the kind of engineer other engineers want to build with. You have spent your career going deep on production systems, and you have reached the point where your judgment shapes architectures, raises teams, and makes hard problems look simple. This is the most senior technical seat in the pod, and it is unapologetically hands-on.

As Technical Lead and Architect, you own the architecture for an OpCo's modernized applications and set the engineering bar the whole pod builds to. You operate as a player/coach: designing complex systems, writing meaningful code, and running rigorous reviews of work produced by both engineers and AI agents. You treat agentic development as a first-class part of the architecture, not a novelty, and you define how the pod gets the most out of it without ever compromising quality or security.

About the Pod :

A TechGrove AI Engineering Pod is a self-contained, AI-native software delivery team that we embed inside one of our Operating Companies (OpCos) to build, modernize, and ship production software. Each pod pairs senior engineering talent with agentic AI tooling such as Claude Code, plus the accelerators of Banyan's AI Application Modernization Factory, to deliver at a velocity and quality bar a traditional team cannot match.

What You Will Do :

- Own the architecture: Define and own the end-to-end software architecture for the pod's applications, ensuring designs are scalable, secure, resilient, and cloud-native across AWS and Azure.

- Own the frontend architecture: Set the frontend architecture: state management, a scalable library of reusable components, design-system integration, and the patterns, standards, and performance budgets the pod builds against.

- Lead the technical direction: Serve as the highest technical authority and escalation point in the pod.

- Stay hands-on: Operate as a player/coach. Make significant code contributions, lead complex designs, and deliver thorough code reviews.

- Lead AI-native development: Define how the pod uses agentic tooling such as Claude Code across the SDLC.

- Set the quality bar: Define and enforce engineering excellence: clean code, Domain-Driven Design, modern design patterns, Twelve-Factor principles, meaningful test coverage, and application security.

- Build secure and reliable systems: Embed secure-by-design principles and cloud-native observability.

- Mentor and raise the team: Coach senior engineers, grow the technical capability of the team, and foster a culture of ownership.

- Partner with the OpCo: Work with the OpCo's technical leadership and existing teams to align architecture with their landscape.

What You Bring :

- Experience: 10+ years in software engineering, with significant time in Principal Engineer, Staff Engineer, or Architect roles.

- Production experience on BOTH AWS and Azure (required): Hands-on depth includes containers (Docker/Kubernetes), serverless (Lambda and Azure Functions), and Infrastructure-as-Code with Terraform.

- Architectural depth: Deep command of modern architectural patterns (microservices, event-driven, distributed systems), DDD, and design patterns.

- Hands-on technical depth: Current, real coding ability. A player/coach who contributes code, leads design, and delivers thorough reviews.

- AI-native engineering: Demonstrated fluency with AI-assisted and agentic development tooling (Claude Code or similar).

- Modern tech stacks: Hands-on production experience with at least two of: .NET Core, Python, TypeScript, and Java.

- Frontend architecture: Deep expertise in modern frontend architecture with React.js and Next.js.

- DevSecOps: Strong command of CI/CD (GitHub Actions, GitLab CI) and modern DevSecOps practices.

Why TechGrove, Why Banyan :

- Permanent home, long-term thinking: Banyan acquires great software businesses and keeps them for good.

- Real ownership: You own outcomes end to end inside a small, senior team.

- AI-native by default: You work every day with agentic tooling and the AI Application Modernization Factory.

- Growth and excellence: A Banyan Director of Engineering Excellence supports every pod with coaching, standards, and continuous improvement.
