Don't know our exact tech stack? That's okay. We view technology as a means to solving problems and creating value for customers. We care more about strong engineering fundamentals, product thinking, and the ability to learn than experience with any specific technology. You'll work across the stack, contributing to everything from intuitive user experiences to scalable backend systems and data platforms. You'll also help shape technical direction, mentor teammates, and influence how we build.

You'll begin meaningful work from day one in a highly impactful role with significant ownership and opportunities for growth.

  • Design, build, and maintain full-stack applications that power Datavant's healthcare data ecosystem
  • Deliver exceptional user experiences by partnering closely with product managers, designers, and fellow engineers
  • Develop scalable frontend applications, backend services, APIs, and data-driven solutions that support millions of healthcare records and transactions
  • Guide technical design decisions and help establish architecture patterns that enable long-term scalability and maintainability
  • Mentor engineers and contribute to a culture of technical excellence, ownership, and continuous learning
  • Own substantial projects end-to-end, from technical design through implementation, deployment, and ongoing operation
  • Drive innovation and deliver valuable solutions that improve outcomes for healthcare organizations and patients
  • Share your expertise with the engineering community through technical discussions, mentorship, and contributions to our engineering blog

Tech Stack You'll Work With

Your work will span Datavant's core platform technologies, including:

  • Backend: Python, Go, Java; microservices; REST and GraphQL
  • Frontend: TypeScript, React, Next.js
  • Infrastructure & Cloud: AWS (EC2, S3, IAM, Lambda), Docker, Kubernetes; IaC tools
  • Data: Snowflake, Spark, SQL; S3 for raw data
  • ETL & Pipelines: Airflow/Glue
  • Streaming: Kafka or Kinesis
  • Observability: DataDog, Grafana, CloudWatch
  • Security: OAuth2/SAML, encryption, tokenization
What You Bring
  • 8+ years of experience designing, building, and operating production software systems
  • Strong full-stack engineering experience, including modern frontend development and backend services
  • Experience building customer-facing applications using technologies such as React, TypeScript, and modern web frameworks
  • Experience designing and developing scalable APIs, distributed systems, and cloud-native applications
  • Ability to write high-quality, maintainable code, perform thoughtful code reviews, and drive engineering best practices
  • Demonstrated experience leading projects from concept to production and successfully navigating complex technical challenges
  • Strong collaboration and communication skills, with the ability to work effectively across engineering, product, and design teams
  • Passion for mentoring other engineers and elevating the technical capabilities of the team
  • Excitement, passion, and curiosity about our mission of connecting the world's health data and improving patient outcomes
Leadership Qualities & Mindset
  • Model accountability and ownership in team projects.
  • Encourage collaboration and technical learning across peers.
  • Maintain curiosity for both technical and business context.
  • Communicate effectively across engineering and product.
  • Demonstrate resilience and adaptability in problem-solving.
Core Value Expectations
  • Earn trust through reliable delivery and proactive risk communication.
  • Obsess over customers by shaping requirements and ensuring system excellence.
  • Prioritize growth over comfort through ongoing architectural development.
  • Win as a team by mentoring, aligning stakeholders, and enabling others.
  • Rise to the challenge by solving complex problems with speed and rigor.
