About The Position

Datavant is the data collaboration platform trusted for healthcare. Guided by our mission to make the world’s health data secure, accessible and actionable, we provide critical data solutions for organizations across the healthcare ecosystem - including providers, health plans, researchers, and life sciences companies. From fulfilling a single patient’s request for their medical records to powering the AI revolution in healthcare, Datavanters are building the future of how data is connected and used to improve health. By joining Datavant today, you’re stepping onto a driven and highly collaborative team that is passionate about creating transformative change in healthcare. What We’re Looking For We’re looking for a Senior Software Engineer who can take end-to-end ownership of a long-lived internal product that is rapidly becoming foundational to multiple organizational initiatives. You will partner closely with the team to accelerate the evolution of our internal system portfolio application, ensuring it is reliable, extensible, and capable of integrating deeply across our ecosystem. This role requires strong, recent hands-on development experience in Golang and modern JavaScript, with a bias toward automation, clean architecture, and pragmatic delivery. You should be comfortable operating with high autonomy—given the “why,” you define the “what,” “how,” and sequencing.

Requirements

Demonstrated experience owning a substantial, long-lived product or platform component end-to-end, including defining scope, driving architecture, coordinating cross-team dependencies, and delivering measurable outcomes.
Strong hands-on experience in Golang and modern TypeScript (SPA frameworks), with the ability to design clean service boundaries and maintainable frontend architectures.
Experience designing and maintaining API integrations across heterogeneous internal and external systems.
Proven ability to lead significant refactors, migrations, or architectural improvements while maintaining system stability and delivery momentum.
A systems-thinking mindset with a track record of improving engineering operations (testing, CI/CD, observability, code health) and balancing feature velocity with reliability and maintainability.
Recent, meaningful hands-on coding experience and comfort performing detailed PR reviews.
Clear communication skills and the ability to collaborate effectively with product, security, and platform engineering teams.
Strong experience designing, deploying, and operating production systems in AWS, with practical knowledge of core services (e.g., EKS, Lambda, RDS, DynamoDB, S3, IAM, CloudWatch), networking, and least-privilege access patterns.
Experience working with infrastructure-as-code tools (e.g., Terraform or similar) to provision and manage AWS resources, with familiarity in modular design and environment promotion workflows.

Nice To Haves

Experience building or operating CMDB-like systems, asset inventory platforms, or internal developer platforms.
Familiarity with security ecosystems, system inventory, or exposure/secrets-related data domains.
Experience working in highly integrated environments where a single system serves as a source of truth for multiple organizational workflows.
Demonstrated effective use of AI-assisted development tools to accelerate delivery, improve code quality, or automate repetitive engineering tasks.
Experience working in environments with strong compliance or security requirements, where correctness and audit-ability matter.
A history of building internal platforms that other engineering teams depend on—and designing for usability, adoption, and long-term extensibility.

Responsibilities

Own significant portions of our internal system portfolio application end-to-end, including architecture, design, implementation, testing, and operational excellence.
Partner with the team to define and execute the long-term technical roadmap for the platform, ensuring it scales as a backbone system across multiple teams and initiatives.
Design and implement backend services in Golang and frontend components in JavaScript for a SPA architecture.
Build and maintain robust integrations with internal systems and third-party/vendor APIs, including designing resilient data ingestion, normalization, and synchronization workflows.
Improve the system’s data model, performance characteristics, and reliability as adoption and use cases expand.
Drive engineering quality: establish patterns for observability, testing strategy, CI/CD integration, and maintainability.
Identify and lead meaningful refactors, migrations, and architectural improvements as the product matures.
Conduct thorough pull request reviews and provide direct technical mentorship to engineers contributing to the system.
Leverage AI-assisted engineering tools (e.g., Claude Code or similar) to accelerate development while maintaining high standards for correctness, security, and maintainability.
Partner with Product, Security, and Platform stakeholders to ensure the application integrates cleanly with broader organizational workflows and technical systems.
