Senior Software Engineer

Position Summary: As theSenior Software Engineer, you will design, build, and ship features end-to-end across Arkana's enterprise software platforms, including our next-generation Laboratory Information System and client-facing ConnectApp. The role spans frontend interfaces, backend services, and integration code that connects our applications to laboratory instruments, partners, and downstream systems. The engineer will collaborate closely with the Engineering Manager, Product Manager, Technical Operations, and our Data Engineering counterparts to deliver clean, reliable user-facing software.

What you'll do: 

• Build features end-to-end across the stack
• Develop and maintain backend services - our current stack is TypeScript and Node.js
• Build user-facing interfaces that translate clinical and operational workflows into clean, usable experiences - we build in Vue
• Build integration services connecting Arkana's applications to laboratory instruments, external partners,
  and third-party systems
• Deploy and maintain services in cloud and hybrid environments
• Contribute to CI/CD pipelines and automated testing
• Enforce security and compliance controls appropriate to a HIPAA-regulated environment
• Write tests, conduct code reviews, and maintain code quality standards
• Document features, APIs, and integration contracts
• Other duties as assigned

You should have: 

Education: Bachelor's degree in Computer Science, Software Engineering, or a related technical field, or
equivalent professional certifications, bootcamps, or experience.

Experience: 5-7 years of professional software engineering experience, with hands-on work across both
frontend and backend. Prior Healthcare, life sciences, or other regulated industry experience preferred.     

Technical Skills

• Strong proficiency in a statically typed, object-oriented or systems language; experience with TypeScript
  and Node.js is preferred, and candidates should be comfortable moving into that stack (Fastify, oRPC
  experience a plus)
• Frontend experience with modern component-based frameworks and dependency injection patterns (Vue
  preferred; React or Angular experience transfers well)
• Strong SQL and working knowledge of relational database design; experience with PostgreSQL and an
  ORM or query-builder (Prisma preferred) is a plus
• Experience designing and consuming REST APIs; exposure to event-driven patterns is a plus
• Experience with at least one major cloud platform (Azure preferred)
• Comfort with Git-based workflows, CI/CD, and modern development practices; experience with
  containerization and container runtimes (Docker)
• Experience with infrastructure as code tooling (Terraform or OpenTofu preferred) and applying common
  cloud best practices around security, scalability, and cost management

Soft Skills

• Strong analytical and problem-solving skills grounded in first-principles reasoning
• Clear, confident communication across engineering, product, and operations - in writing, in design
  artifacts, and in conversation
• Ability to work independently with sound judgment while actively contributing to a collaborative, open
  team environment
• Attention to detail and pride in delivering reliable, well-tested work

Other Qualifications

• Working understanding of healthcare data privacy, HIPAA, and PHI handling
• Familiarity with FHIR (HL7 R4) or other healthcare integration patterns is a plus
• Familiarity with Model Context Protocol (MCP) is a plus
• Familiarity with Claude and the Claude ecosystem of tools and features is a plus

Differentiating Background

• You lead with first principles - you know which engineering principles and patterns apply to a given
  problem, and more importantly, when they don't. You know the difference between applying a principle
  and hiding behind one. That same discernment extends to AI - you value your autonomy and judgment in
  a world of AI sycophancy, reaching for it when it eliminates real drag and ruling it out when it doesn't.
• You prefer as little magic as possible - dependencies are wired explicitly, ownership is clear, and nothing
  happens behind the scenes that you didn't put there. You prefer explicit over implicit, interfaces at the
  boundary over deep inheritance, and errors as first-class values - typed, explicit, and handled at the right
  layer.
• You communicate with clarity and conviction - whether through an RFC, a design document, an
  architecture diagram, a coding agent spec, or a message in chat. You don't just have opinions; you can
  write them down and defend them.
• You multiply the people around you. You mentor through code review, in chat, and in person - with the
  company, the team, the individual, and yourself in mind. You keep conversations open and push back on
  silos.
