Software Engineer, Backend Developer, Cloud Engineer - Software

Position: Software Engineer 3
About The Cloud Payments Team
Cloud Payments is part of the Cloud Billing organization. As Mongo

DB’s Cloud business grows, the billing and payments stack becomes increasingly mission‑critical. Our team:

Ingests and aggregates detailed metering and usage data from internal services and major cloud providers (AWS, Azure, GCP)

Calculates and generates daily customer bills for millions of customers worldwide

Integrates with payment processors and internal financial systems to support Finance, Sales, Marketing, and Accounting

Continuously improves customer‑facing billing and payments experiences and the reliability and scalability of our backend systems

We’re a group of engineers who care deeply about code quality, correctness, and observability, and who are comfortable collaborating with both highly technical partners and non‑technical stakeholders across the business.

The role
We’re looking for a Software Engineer 3 to help design, build, and operate the services that power Cloud Payments. You’ll work primarily in the JVM ecosystem (Java and related tooling), with a focus on large‑scale, distributed systems that have to be correct, resilient, and auditable.

This is a Canada‑based, fully remote role. You’ll collaborate closely with teammates and stakeholders across North America time zones, including engineers in the broader Cloud Billing organization.

What You’ll Do

Design, implement, and operate backend services that ingest, process, and reconcile large volumes of usage and billing data from internal and external systems

Collaborate with product, Finance, Revenue, and other engineering teams to evolve our billing and payments capabilities and improve customer experience

Own features end‑to‑end: requirements, design, implementation, testing, rollout, monitoring, and iterative improvement

Help scale and harden our systems as Atlas and our broader Cloud business continue to grow rapidly

Participate in architecture discussions, technical design reviews, and code reviews to keep our systems robust and maintainable

Contribute to improving our tooling, observability, and development workflows so the whole team can move faster and safer

Take part in an on‑call rotation that treats reliability as a team sport, not an individual burden

What We’re Looking For

Have 3+ years of experience building and maintaining backend systems in a compiled language, ideally Java

Understand core object‑oriented design principles and how to apply them to complex, evolving systems

Have experience with distributed systems and services that need to be highly available, observable, and correct at scale

Are comfortable working with databases (relational and/or non‑relational such as Mongo

DB) in production environments

Communicate clearly and enjoy working with both technical and non‑technical stakeholders across multiple teams

Are curious, collaborative, and motivated by solving real customer and business problems rather than just closing tickets

Nice to have (but not required)

Experience with billing, payments, or other financial systems where correctness, auditability, and compliance really matter

Experience with cloud platforms (AWS, GCP, Azure) and modern communication protocols like gRPC

Familiarity with data‑intensive applications, data pipelines, or data lakes

Exposure to working with I/O frameworks like Reactor

Experience with containerization and orchestration (e.g., Docker, Kubernetes)

Prior exposure to Mongo

DB as a developer or operator

We don’t expect you to check every box. If you’re excited about the space and think you could do great work here, we’d love to hear from you.
