About the Role:

We are seeking a Full-Stack Developer (Backend-Focused) with 5+ years of software engineering experience to join our 7-person technology team, led by a CTO who provides overall technical direction.

This role is ideal for an engineer who enjoys solving practical, real-world technical problems, taking ownership of their work, and building reliable solutions across our technology stack, with a primary focus on backend development.

The Ideal Candidate:

Quickly understand existing code:
Able to get up to speed on an existing codebase and begin making meaningful contributions quickly.

Improve rather than over-engineer:
Comfortable working within existing systems and making practical improvements without unnecessary rewrites.

Strong problem-solving:
Able to break down complex technical problems and identify practical, effective solutions.

Good technical judgment:
Makes thoughtful decisions around architecture, implementation, performance, and maintainability.

Production-focused:
Builds reliable, scalable software that is well-tested and ready for production use.

Key Responsibilities:

• Backend & Integrations:
  Design, build, and maintain robust backend services, REST APIs, and third-party platform integrations (payment gateways, clinical databases, operational tools).
• Data Pipelines & Warehousing:
  Improve data pipelines, Big Query architecture, and reporting infrastructure to ensure 100% data integrity, monitoring, logging, and alerting.
• Workflow Automation & AI:
  Build AI-powered agents and workflow automations using LLMs and modern frameworks to eliminate manual administrative and operational effort.
• Full-Stack Execution:
  Own existing codebases incrementally; contribute to React-based internal tools, dashboards, and operational interfaces as needed.

Qualifications:

Non-Negotiable: AI & Automation Experience

• Must have hands-on experience building and deploying real-world applications using LLM APIs, AI agents, or modern AI frameworks (e.g., Lang Chain, Lang Graph, PydanticAI).
• Actually built and shipped AI-powered features or automations, not simply experimented with AI tools or used LLMs as part of their development workflow.

Non-Negotiable:
Sensitive & Regulated Data Experience

• Must have professional experience working with sensitive, confidential, or highly regulated data in a production environment.
• This includes experience with data requiring strong security, privacy, access controls, compliance, or regulatory safeguards.
• Relevant experience may come from Health Tech, Fin Tech, Legal Tech, Gov Tech, or other industries where protecting sensitive data is a core part of the technology environment.
• Candidates should understand the practical requirements of building and maintaining systems where data security, privacy, and compliance cannot be treated as an afterthought.

Core Technical Stack
