Principal Software Development Engineer - (Flowise)

About the Role

We are seeking a Principal Software Development Engineer to serve as the technical anchor and platform architect for Flowise. This is a hands-on leadership role that combines deep system design expertise, strong coding capability, and cross organizational technical influence.

You will define and drive the long term architectural vision for Flowise as an extensible AI platform across open source, SaaS, and Workday enterprise environments. You will own critical systems, influence architectural direction across teams, and write production code that ships.

What You Will Do

Platform Architecture & Vision:

• Define and evolve the shared platform layer powering Flowise across open source, cloud, and enterprise deployments.

• Design modular SDKs, runtime systems, and integration patterns that ensure portability, extensibility, and long term maintainability.

• Own end-to-end system design including APIs, data models, service boundaries, and deployment strategies

​AI Systems Leadership:

• Lead architectural decisions for AI agent design patterns, LLM orchestration, RAG pipelines, evaluation frameworks, model routing, safety guardrails, and performance optimization.

• Drive production reliability, observability, and cost efficiency strategies for AI workloads.

Open Source & Enterprise Bridge:

• Define the roadmap for open source and enterprise, and design workflows that allow both codebases to evolve without creating maintenance debt.

• Represent Flowise in cross organizational architectural discussions and influence standards for enterprise AI deployment within Workday.

Hands On Engineering:

• Contribute directly to the TypeScript monorepo (Node.js, React, Express).

• Review pull requests, debug complex issues, and participate in production on call rotations.

Engineering Excellence & Mentorship:

• Raise the bar on testing practices, CI/CD pipelines, and observability standards.

• Mentor senior engineers and influence technical direction through design reviews and collaboration.

About You

Basic Qualifications

• 8+ years of software engineering experience building large scale production systems.

• 6+ years of experience and expertise in JavaScript/TypeScript, Node.js, and React.

• 6+ years of experience architecting distributed systems and scalable APIs, with a strong background in relational databases, cloud infrastructure (AWS preferred), and CI/CD tooling.

• Track record of owning systems from requirements through production operations.

Other Qualifications

• Experience building production AI systems (LLM applications, RAG pipelines, agent frameworks).

• Experience with MCP, LangChain, or similar orchestration frameworks.

• Hands-on experience with Docker, Kubernetes, and Infrastructure as Code.

• Experience with authentication protocols (OAuth, JWT, SSO), multi tenant systems, and embedding applications within host platforms.

• Experience influencing architectural decisions across multiple teams or organizations.

Communication & Leadership

• Ability to clearly communicate complex architectural decisions to engineers, product leaders, and executive stakeholders.

• Demonstrated ability to lead through influence rather than authority.
