About the Role

We're looking for a Backend Engineer, Billing & Revenue Systems to help build and maintain the backend services supporting payments, subscriptions, billing workflows, and revenue-related functionality across Bask Health's telehealth platform.

You'll develop APIs, application logic, and integrations that connect patient checkout, merchant billing configuration, subscription management, and payment processing.

This is a hands-on engineering role for someone with experience building production backend applications and working with transactional data. You'll implement meaningful features, investigate billing issues, and help improve the accuracy and reliability of systems used by merchants, patients, and internal teams.

Our backend stack includes TypeScript, Node.js, AWS, SST, and SQL databases, with technologies such as Prisma and Drizzle used across the platform.

You'll collaborate with engineers, product managers, finance, and operations teams to translate business requirements into reliable technical solutions.

We're looking for someone who pays attention to details, understands the importance of data accuracy, and enjoys solving backend problems that directly affect real transactions and customer experiences.

What You'll Do

• Build, test, and maintain backend services supporting payments, subscriptions, billing, and revenue-related workflows.
• Develop APIs and application logic for subscription creation, renewals, cancellations, payment status updates, and billing changes.
• Implement backend features using TypeScript, Node.js, AWS, SST, and SQL databases.
• Build and maintain integrations with payment processors and third-party billing services.
• Work with payment events, webhooks, and asynchronous processing to keep billing records up to date.
• Help implement pricing rules, discounts, trials, and billing configuration across merchant and patient workflows.
• Create and maintain database models for transactions, subscriptions, invoices, and billing events.
• Implement validation, error handling, retries, and safeguards against duplicate transaction processing.
• Work with AWS services such as Lambda, SQS, and EventBridge to support background jobs and event-driven workflows.
• Help investigate discrepancies between internal billing records and external payment systems.
• Build automated tests for billing logic, subscription changes, payment failures, and common edge cases.
• Troubleshoot production issues, investigate failed payments or unexpected billing behavior, and help implement lasting fixes.
• Improve logging, monitoring, and visibility into billing system performance.
• Collaborate with finance and operations teams to understand recurring billing issues and reporting needs.
• Work with product managers and senior engineers to break requirements into technical implementation tasks.
• Participate in code reviews, technical planning, and engineering discussions.
• Follow secure development practices when handling payment-related and sensitive customer information.
• Contribute to internal tools that help teams investigate transactions and resolve billing issues.
• Document APIs, billing workflows, and important system behavior.
• Use AI-assisted development tools such as Cursor and Claude Code to support development, debugging, and testing while reviewing generated code carefully.
• Take ownership of assigned features from implementation through testing, deployment, and follow-up.
• Help improve existing billing services and contribute ideas for making transaction processing more reliable and maintainable.

Requirements

• 3+ years of professional software engineering experience, including hands-on backend development.
• Strong proficiency in TypeScript, JavaScript, and Node.js.
• Experience building, testing, and maintaining production backend applications and APIs.
• Experience working with SQL databases, relational data models, and database schema design.
• Practical experience with AWS or comparable cloud infrastructure.
• Experience integrating third-party APIs, processing webhooks, or implementing asynchronous backend workflows.
• Understanding of transactional data integrity, error handling, and reliable data processing.
• Familiarity with serverless applications, background jobs, or event-driven architectures.
• Experience using modern database access tools or ORMs.
• Understanding of authentication, authorization, and secure handling of sensitive information.
• Ability to implement backend features involving complex business rules and state changes.
• Experience writing automated tests and debugging production applications.
• Familiarity with Git, code reviews, and modern software development workflows.
• Ability to troubleshoot technical issues and communicate findings clearly.
• Comfortable using AI-assisted development tools while independently reviewing and validating generated code.
• Ability to complete assigned features independently and collaborate with senior engineers on more complex projects.
• Strong problem-solving skills and attention to detail, particularly when working with transactional data.
• Good written and verbal communication skills.
• Comfortable working in a fast-moving environment where engineers take ownership of their work.

Nice to Have

• Experience building payment processing, billing, or subscription management systems.
• Experience integrating Stripe or comparable payment processors.
• Familiarity with recurring billing, subscription renewals, cancellations, refunds, or failed-payment recovery.
