• Write clean, maintainable code: Author services in Go (or a similar language) and SQL (Postgres or equivalent), following clear coding standards and review practices.
• Drive quality & reliability: Implement unit, integration, and end-to-end tests; instrument metrics (throughput, latency, error rates) and alerts; rapidly diagnose and resolve issues.
• Collaborate & iterate: Partner with Product and Operations to deliver features quickly; pair with teammates to share knowledge and continuously refine our tooling and processes.

What we’re looking for

We're seeking a talented Senior Software Engineer to join our mission of revolutionizing payments for service-based companies by building the robust, scalable infrastructure that powers our accounts receivable automation platform.

You’ll join our Product Expansion team, which owns two of our core products: Accounts Payable, where we’re currently building multi-use virtual cards, and Analytics.

This role is ideal for someone who thrives on architecting and developing core backend services, design event-driven data pipelines, and ensuring the reliability and performance of systems that process critical financial transactions for our clients.

Working closely with Product and Operations teams, you'll leverage your expertise in Go (or other similar language) and distributed systems to deliver high-quality features rapidly while maintaining the transparency, dependability, and partnership values that define Alternative Payments.

This is an opportunity to make a direct impact on how businesses manage their payment processes, contributing to a platform that reduces costs and complexity for companies while working alongside a global, diverse and collaborative team.

This role is available to candidates who are eligible to work in Brazil, fully remote.

What you’ll bring

• Strong in Go (or comparable backend language) and SQL (Postgres or equivalent).
• Experience working on payment platforms or with payments/financial transactions.
• Comfortable with event buses/queues (Kafka, RabbitMQ, etc.).
• Solid testing discipline: unit, integration and end-to-end.
• Familiarity with Git workflows, code reviews and CI/CD pipelines.
