Senior Backend Engineer, Pharmacy Integrations

Bask Health

About The Position

Bask Health is seeking a Senior Backend Engineer to design, build, and maintain systems connecting its telehealth platform with pharmacy partners and fulfillment operations. The role focuses on backend services for prescription routing, pharmacy order processing, fulfillment updates, and reliable information exchange with external systems. The engineer will own complex integrations involving asynchronous workflows, third-party dependencies, and failure handling, and will build services using TypeScript, Node.js, AWS, SST, and SQL databases. The role works closely with engineers, product managers, pharmacy operations, internal teams, and external technical partners to translate operational needs and integration requirements into scalable technical solutions. The engineer is expected to own integrations from design through deployment and ongoing maintenance, while ensuring systems are secure, observable, maintainable, and resilient. Bask describes its engineering approach as AI-first and builder-led, using tools such as Cursor and Claude Code while independently validating correctness, security, and reliability.

Requirements

At least 5 years of professional software engineering experience, including substantial backend development experience.
Strong proficiency in TypeScript, JavaScript, and Node.js.
Experience designing, building, and maintaining production backend applications and APIs.
Hands-on experience integrating third-party services using REST APIs, webhooks, or similar technologies.
Experience with AWS services and serverless architectures.
Familiarity with AWS Lambda, SQS, EventBridge, or comparable event-driven infrastructure.
Strong experience with SQL databases, relational data modeling, and database schema design.
Experience with modern database access tools or ORMs such as Prisma or Drizzle.
Understanding of asynchronous processing, message queues, distributed systems, and integration architecture.
Ability to design reliable systems that handle retries, failures, duplicate events, and inconsistent external data.
Experience implementing authentication, authorization, secure API communication, and sensitive-data protection.
Strong debugging and troubleshooting skills, including investigation of production integration failures.
Experience writing automated tests for APIs, backend services, and integration workflows.
Ability to independently own complex engineering projects from technical design through production deployment.
Strong understanding of performance, reliability, monitoring, and maintainability in production systems.
Experience making architectural decisions and evaluating technical tradeoffs.
Familiarity with Git, code reviews, CI/CD workflows, and modern software development practices.
Ability to use AI-assisted development tools effectively while independently validating generated code.
Strong written and verbal communication skills, including coordinating technical work with internal teams and external partners.
Comfort working in a fast-moving environment with significant ownership and responsibility.
