We are looking for a senior software engineer to help deliver the AVA Modernization program, moving a legacy platform to a cloud-native architecture using NX monorepo, NestJS services, event-driven integration, and MongoDB/Snowflake data patterns. This is a hands-on role with architecture influence across BFF, microservices, ingestors, and workers.
Key Responsibilities
- Build and scale services within a single NX monorepo using shared libraries and dependency-aware CI/CD.
- Develop and evolve a NestJS BFF Gateway for multiple frontends, including JWT validation and OBO token exchange with Azure Entra ID.
- Implement internal NestJS microservices with clear domain ownership and independent deployment.
- Build ingestion services that consume external events, transform payloads, persist operational data, and publish internal domain events.
- Develop async workers that process internal events for side effects (notifications, indexing, jobs) without tight service coupling.
- Contribute to data-layer design:
- MongoDB for operational/current-state reads
- Snowflake for analytical/reporting workloads
- Create and maintain shared libs/ contracts (DTOs, event payloads, auth utilities, API clients, validation rules).
- Ensure strong testing, observability, performance, and production reliability standards.
Required Qualifications
- 5-10 years of backend engineering experience.
- Strong hands-on expertise with NestJS (modules, DI, guards, interceptors, pipes, validation, Swagger/OpenAPI).
- Practical experience with NX monorepos (shared libs, dependency graph, affected builds/tests).
- Advanced TypeScript/Node.js skills and API/event contract design.
- Experience with event-driven systems (Kafka or equivalent), including retries, idempotency, and schema/version evolution.
- Experience building BFF/API orchestration layers across multiple upstream services.
- Solid MongoDB experience for low-latency operational workloads.
- Strong communication and collaboration skills in cross-functional delivery teams.
Preferred Qualifications
- Ability to navigate and analyze C# and/or Java codebases at a working level — a significant portion of source-of-truth analysis will involve reading and interpreting existing legacy code in these languages to understand current business logic and inform how it should be reshaped to fit the new architecture.
- Experience with Azure Entra ID and OAuth/OBO flows.
- Exposure to GraphQL supergraph integrations from BFF layers.
- Snowflake or similar analytical platform experience.
- Experience migrating legacy services to containerized/cloud-native architectures.
- Kubernetes/OpenShift delivery exposure.
