Job Description
Senior Backend Developer
Sharetru
• Design and implement a connector framework (authentication, config, throttling, error handling, versioning) for systems like SharePoint/Microsoft 365, email delivery, and other third-party services. • Implement OAuth2/OIDC patterns, token refresh, secure secret storage, and least-privilege scopes. • Build durable job scheduling and orchestration: queues/workers, retries with backoff, idempotency, state machines, and replayability. • Create workflow primitives for file movement (trigger → validate → transfer → post-process → notify → audit), including approvals and exception paths. • Extend and maintain secure transfer support for HTTPS, FTPS, FTPeS, SCP, including troubleshooting real-world edge cases (timeouts, cipher/KEX mismatches, passive/active FTP, resumability, large file behavior). • Improve performance and correctness: resumable transfers, checkpointing, integrity verification, and failure isolation (noisy-neighbor control). • Contribute to architecture decisions, code reviews, security assessments, and performance optimization. • Improve observability (logs/metrics/traces), incident readiness, and operational tooling. • Mentor engineers and help evolve development practices.

- Experience with background processing and scheduling (queues/workers, concurrency control, idempotency, retry semantics).
- Strong security mindset: secrets management, auditing, access control, and safe-by-default designs.
- Nice-to-have**
- Microsoft Graph / SharePoint integration experience (delta queries, upload sessions, webhook subscriptions, throttling).
- Understanding of Hyperscaler (Azure, AWS, GCP) platforms, API options, and integrations
- Workflow/orchestration frameworks or building state-machine-based execution.
- Experience with compliance-heavy environments (audit logging, retention, immutable event trails).
