Senior Node.js Backend Engineer

About the role

We are looking for a Senior Backend Engineer to join the Core Banking Services team and help build and scale a high-performance Banking-as-a-Service (BaaS) platform. We build and scale the high-performance, serverless API layer that empowers both internal consumers and partner banks to manage customers and their accounts.

As a pure backend engineering team, we don't build UI components. Instead, we focus entirely on engineering robust, highly available, and secure distributed services. The team owns the end-to-end lifecycle of core banking entities, including:

- Identity & Compliance: Automated customer onboarding and complex KYC workflows.

- Ledger & Accounts: Scalable deposit account management systems.

- Reporting: High-throughput data processing for reporting obligations, observability, and account statement generation.

Responsibilities:

- Build and maintain the BaaS API services, including REST API and event-driven systems with a serverless architecture that other teams and partners depend on, making sure they're reliable and accurate.

- Help shape how we solve problems: contribute ideas on how things should be built, weigh in on important decisions, and make sure we're building things the right way for the long term.

- Keep our CI/CD processes healthy: spot when things are slow or breaking, and take action to make the team's day-to-day smoother and faster.

- Drive architectural decisions and solution design within your domain, including writing technical solution designs, participating in threat modeling workshops, and collaborating cross-team on upstream/downstream dependencies.

- Take ownership of production reliability by participating in an On-Call rotation, leading incident investigations, identifying root causes, and driving hotfixes, as the team does with live incidents on the platform.

- Work with external partners and services we connect to, and take ownership when something on their side needs following up or resolving.

- Keep our build, testing, and release processes healthy: spot when things are slow or breaking, and take action to make the team's day-to-day smoother and faster.

Must have:

- Minimum 5 years of hands-on experience as a backend engineer, with at least 2 years of NodeJs/TypeScript experience.

- Highly responsible for working with critical high-core value systems for the company.

- Solid experience with AWS Serverless services - Lambda, SQS, API Gateway, EventBridge, DynamoDB, S3.

- Solid understanding and practical application of design patterns

- Hands-on experience with Infrastructure as Code (preferably Terraform & CDK).

- Hands-on experience with TypeScript testing practices (unit, integration, system testing).

- Experience with event-driven architectures (e.g., Kafka)

- Familiarity with RESTful API design and OpenAPI specifications.
