Software Developer Jobs in Andover, MA (NOW HIRING)

Who We Are:
Interra Health is a fast-growing healthcare technology company transforming how providers and patients navigate the prescription journey. Formed through the merger of DoseSpot, Arrive Health, and pVerify, Interra Health delivers trusted eligibility, real-time coverage and pricing insights, prescribing tools, and pharmacy transparency at the point of care—helping providers make informed decisions and patients access the right medications with greater clarity and affordability. Backed by strong market momentum and a bold vision for the future of connected care, Interra Health offers the chance to join an innovative, mission-driven team working at the intersection of software and healthcare to reduce friction, improve access, and make the healthcare experience better for everyone.

The Role:

As a Senior Software Developer, you will design, build, and maintain modern, scalable

cloud-native applications using .NET (C#) and React on Microsoft Azure. Contributing

across the full stack, you will deliver performant backend API services and intuitive front-

end experiences that support product growth and platform stability — on a system that

demands high concurrency, high transaction volumes, and exceptional reliability.

You will work cross-functionally with product, cloud, and engineering teams to deliver high-

performance solutions that improve patient outcomes and modernize how healthcare is

delivered. You bring deep technical expertise, a cloud-native mindset, and an AI-first

approach to every layer of the software development lifecycle.

Key Responsibilities:

Backend Development

• Design and build robust, scalable, and maintainable backend services using .NET Core (C#), following clean architecture and SOLID principles.

• Develop and maintain RESTful and event-driven APIs capable of sustaining high-throughput, concurrent workloads.

• Develop data access layers using MS SQL Server, with a strong emphasis on query optimization, indexing strategies, connection pooling, and transaction management for high-volume environments.

• Implement resilience patterns including circuit breakers, retry policies to ensure system stability under load.

Design and deploy cloud-native solutions leveraging core Azure services:

• Azure App Services — hosting and scaling web APIs and front-end applications.

• Azure Function Apps — building lightweight, event-driven compute components.

• Azure Event Grid — designing reactive, decoupled event-driven architectures for distributed systems.

• Azure Storage Accounts — implementing Blob Storage, Queue Storage, and Table Storage for scalable data and messaging needs.

Frontend Development:

• Build responsive, performant user interfaces using React 18+ (TypeScript strict mode), following hooks-only, functional component patterns within an Nx monorepo structure.

• Develop within and contribute to an internal design system built on Mantine, preferring shared component abstractions over raw library usage.

• Implement scalable data-fetching using React Query and internal API hooks, with clean separation of server state from UI state.

• Write frontend tests using Jest and React Testing Library, maintaining 90%+ line coverage with mock-first patterns for all API hooks and external dependencies.

• Collaborate with UX/design to translate wireframes and specifications into responsive UI experiences.

• Optimize frontend performance for scalability through lazy loading, code splitting, and efficient rendering strategies.

AI-First Engineering:

• Apply an AI-first mindset to daily development — leveraging AI-powered tools such as GitHub Copilot, Claude Code, and AI-assisted testing and observability platforms as foundational instruments to accelerate productivity and elevate code quality.

• Evaluate and champion the adoption of emerging AI tooling across the engineering team, driving continuous improvement in how the team designs, builds, and validates software.

Quality Engineering:

• Write comprehensive unit, integration, and end-to-end automated tests as a core part of the development workflow — not an afterthought.

• Champion a test-first culture, ensuring testability is a primary design consideration in every feature and service.

• Participate actively in code reviews, maintaining high standards for correctness, performance, security, and long-term maintainability.

Core Skills and Collaboration:

• Collaborate with product owners, and DevOps engineers to deliver cohesive, reliable solutions

• Contribute to system design, architecture decisions, and performance optimizations

• Support software delivery through CI/CD pipelines across QA, Staging, and production environments.

• Write clean, maintainable, and well-tested code following industry best practices

• Participate in code reviews, mentoring, and knowledge sharing across the team

• Ensure secure, reliable, and compliant systems in a regulated environment (e.g., healthcare or finance if applicable)

What You’ll Bring:

• Bachelor’s degree in Computer Science or a technology-related field; or equivalent experience with at least ten (10) years of strong technical experience in .NET (C#) and React.

• Solid understanding of API design, REST principles, authentication/authorization (OAuth2, JWT, etc.)

• Proficiency with SQL Server and data modeling.

• A minimum of three (3) years of practical experience in Microsoft Azure.

• Experience with React, JavaScript/TypeScript and full-stack development required.

• Familiarity with CI/CD workflows using Azure DevOps or GitHub Actions.

• Experience working in agile/scrum methodology.

• Detail oriented with the ability to multitask, manage time, and communicate effectively.

• Demonstrated ability to independently apply a broad range of theories, concepts, principles, and methodologies to product projects involving complex features.

• Experience with microservice architecture, CQRS, or event-driven design preferred.

• Exposure to containerization technologies like Docker or Kubernetes preferred.

• Experience in regulated industries such as healthcare or finance preferred.

• Familiarity with monitoring, logging, and observability tools (e.g., App Insights, OpenTelemetry) preferred.
