Full-Stack Software Engineer

PartsSource is investing in a next‑generation, enterprise‑grade platform for digital and immersive training in Healthcare Technology Management (HTM). The platform will power our AI‑enabled labor‑enablement strategy by offering interactive training, real‑time guidance, and curated knowledge to Technicians and Clinical Engineers.

As our Full-Stack Software Engineer, you’ll play a key role in shaping and building the platform architecture and web clients from the ground up. Working closely with product and technology leads, you’ll help deliver a modern, scalable, and modular system that supports seamless integration and rapid iteration. You’ll own core features end to end, influence technical decisions, and contribute to a culture of engineering excellence within a fast-paced, collaborative team.

What You’ll Do

Architecture & Implementation

• Design and implement modular, scalable components across a modern React/Next.js front-end and a Node.js/PostgreSQL back-end.
• Influence architecture decisions and define foundational patterns for a new platform built to scale across product lines.
• Translate product and UX designs into performant, responsive, and maintainable interfaces while enforcing design standards and systems.

API & Integrations

• Develop and maintain robust RESTful APIs and third‑party service integrations.
• Implement SSO/SAML authentication flows for enterprise access and user provisioning.
• Expose well‑documented internal APIs to enable integration with other clients and services.

AI Development

• Prototype and ship AI-powered experiences using language models, embedding-based search, and memory/context management.
• Build and refine internal tooling and workflows for deploying AI capabilities across the platform.
• Collaborate with product and immersive teams to embed AI in training, support, and guidance features.

Performance, Maintenance, & Quality

• Optimize data-fetching and caching strategies across the full stack.
• Write and maintain tests to ensure long-term reliability.
• Improve local development environments, automation scripts, CI/CD, and documentation for team velocity.
• Monitor application and dependency health, respond to issues, and implement observability practices (logs, metrics, alerts).
• Identify and implement architectural improvements that elevate performance, security, and developer experience.

Team Collaboration

• Participate in code reviews and share knowledge with team members. 
• Collaborate closely with Unity and Web developers to ensure a seamless bridge between 2D and immersive experiences.
• Partner with product and design to rapidly iterate on prototypes.

Experience and Knowledge

• 5+ years of professional experience in full-stack web development, with at least 2+ years building production applications with React and Node.js.
• Strong proficiency in JavaScript and TypeScript for full-stack development.
• Deep experience with React and Next.js for building scalable, performant front-end applications.
• Solid understanding of Node.js, PostgreSQL, and relational data modeling.
• Familiarity with modern back-end platforms such as Supabase, including authentication, storage, and database integration.
• Proficient in REST API design, third-party API integration, and secure authentication flows (SSO/SAML).
• Comfortable with frontend state, data-fetching, and caching strategies (e.g., TanStack Query/React Query).
• Competence in unit and integration testing and version control workflows using Git & GitHub.
• Working proficiency in Python, especially for automation and integrating AI/ML tools.
• Hands-on experience developing and shipping AI-powered features or prototypes, ideally in production environments.
• Experience using and integrating AI services (e.g., OpenAI, Anthropic, LangChain, embeddings, vector search).
• Familiarity with building or extending AI-enhanced workflows (e.g., chat, search, memory).

What You’ll Bring

• Builder’s Mindset – You thrive on bringing ideas to life through rapid prototyping and iterative development.
• Bias for Action – You are a self-starter who can take ownership of features from idea to deployment.
• System Thinking – You think in terms of scale, modularity, and extensibility—balancing today’s needs with tomorrow’s opportunities.
• Craft & Care – You write clean, readable, and tested code and champion technical excellence in every aspect of your work.
• Clear Communicator – You work well with product, design, and stakeholders. You know how to explain trade-offs, give thoughtful feedback, and document decisions for teammates and future-you.
• Curiosity for Emerging Tech – You’re energized by AI, VR/MR, and new ways to train, support, and empower users.

What We Value

• Act Like an Owner – You take responsibility for outcomes and quality.
• Serve with Purpose – You care about the safety, training, and impact of HTM professionals.
• Adapt to Thrive – You’re excited to work across physical, digital, and immersive domains.
• Collaborate to Win – You respect others’ expertise and build effective working relationships.
• Challenge the Status Quo – You seek better ways to train, represent, and validate medical procedures.
