[Hiring] Senior Backend Engineer @Bask Health

Role Description

We're looking for a Senior Backend Engineer, Billing & Revenue Systems to design, build, and improve the backend infrastructure supporting payments, subscriptions, billing workflows, and revenue operations across Bask Health's telehealth platform.

• Work on systems that connect merchant configuration, patient checkout, recurring payments, billing records, and financial reporting.
• Ensure transactions are processed reliably, subscription changes are handled correctly, and financial information remains accurate across the platform.
• This is a hands-on engineering role requiring strong technical judgment, experience with complex backend systems, and the ability to independently own projects from architecture through production.
• Collaborate with product managers, engineers, finance, and operations teams to develop scalable systems that support the financial side of running telehealth businesses.
• Understand that billing systems need accurate data, predictable behavior, clear error handling, and reliable recovery when something goes wrong.

Qualifications

• 5+ years of professional software engineering experience, including substantial hands-on backend development.
• Strong proficiency in TypeScript, JavaScript, and Node.js.
• Experience designing, building, and maintaining production backend services and APIs.
• Professional experience integrating third-party APIs, processing webhooks, or building event-driven backend systems.
• Experience working with AWS services and serverless architectures.
• Familiarity with AWS Lambda, SQS, EventBridge, or comparable asynchronous processing infrastructure.
• Strong experience with SQL databases, relational data modeling, and database schema design.
• Experience with modern ORM or database access tools such as Prisma or Drizzle.
• Strong understanding of transactional data integrity, consistency, and reliable backend processing.
• Experience implementing idempotency, retries, error handling, and recovery mechanisms for critical workflows.
• Ability to design backend systems that support complex business rules and state transitions.
• Strong understanding of API security, authentication, authorization, and secure handling of sensitive information.
• Experience writing automated tests, debugging production systems, and maintaining high software quality.
• Ability to independently own complex engineering projects from architecture through deployment.
• Experience making architectural decisions and evaluating technical tradeoffs.
• Familiarity with Git, code reviews, CI/CD, and modern software development practices.
• Ability to use AI-assisted development tools effectively while independently validating generated code.
• Strong analytical thinking, attention to detail, and problem-solving skills.
• Excellent written and verbal communication skills.
• Ability to collaborate with product managers, engineers, finance, and operations teams.
• Comfortable working in a fast-moving environment with significant ownership and responsibility.

Requirements

• Design, develop, and maintain backend services supporting billing, payments, subscriptions, and revenue-related workflows.
• Build and improve integrations with payment processors and external billing services.
• Develop APIs and application logic for subscription creation, renewals, cancellations, plan changes, and payment status updates.
• Help implement pricing, discount, trial, and billing configuration logic across merchant and patient workflows.
• Design reliable processing for payment events, webhooks, and asynchronous billing updates.
• Build services using TypeScript, Node.js, AWS, SST, and SQL databases.
• Use AWS Lambda, SQS, EventBridge, and related services to support event-driven billing workflows.
• Design database schemas and data models for transactions, subscriptions, invoices, billing events, and financial records.
• Develop mechanisms to prevent duplicate charges, inconsistent billing states, and lost payment events.
• Implement retry logic, idempotency, validation, and error handling for payment-related operations.
• Help build reconciliation processes that identify discrepancies between internal billing records and external payment providers.
• Improve the reliability, performance, and maintainability of existing billing services.
• Collaborate with finance and operations teams to understand billing issues, reporting needs, and operational requirements.
• Work with product managers and engineers to translate business requirements into technical designs.
• Develop internal tools and workflows that make billing issues easier to investigate and resolve.
• Build appropriate access controls, audit trails, and safeguards around sensitive billing information.
• Create automated tests covering billing calculations, subscription transitions, payment failures, and other edge cases.
• Investigate production incidents, identify root causes, and implement durable fixes.
• Improve monitoring, logging, alerting, and visibility into billing system performance.
• Review code, provide technical guidance, and contribute to engineering standards.
• Take ownership of complex billing initiatives from design and implementation through deployment and production support.
• Use Cursor, Claude Code, and other AI-assisted development tools to accelerate development while independently validating correctness, security, and maintainability.
• Help establish reusable billing architecture that supports additional products, merchants, and business models.

Benefits

• Competitive salary and equity options.
• Flexible working hours and remote work opportunities.
• Comprehensive health benefits.
• Professional development and training opportunities.
• Collaborative and innovative work environment.
