Senior Backend Engineer
Sharetru
Sharetru is a long-standing, security-first managed file transfer platform. We’re expanding beyond traditional transfers into a more modern integration and automation layer: connectors (SharePoint/Microsoft 365, email, SIEM, cloud storage), workflow-driven file movement, and reliable job scheduling—while maintaining the protocol-level depth (SFTP/FTPS/FTPeS/SCP) our customers rely on. The MFT and secure data exchange market is growing fast — driven by rising compliance requirements, ransomware threats, and the increasing complexity of data ecosystems. According to recent industry research, the MFT market is projected to exceed $4.0 billion by 2030, fueled by demand for automation, encryption, and auditability in data sharing. Organizations are shifting away from consumer-grade tools and turning to specialized platforms built for compliance and control. We’re one of them—and we’re just getting started. If you enjoy building systems that must be secure, observable, and resilient under real-world failures, this role is for you. Build the next-gen integration layer - 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. Evolve workflows + scheduling into a first-class platform capability - 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. Strengthen MFT reliability and protocol depth - 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). Raise engineering quality - 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.
Job Requirements
- U.S. Citizenship
- 10+ years of backend development experience, ideally in a SaaS or infrastructure-heavy environment
- Senior-level backend experience shipping production systems (SaaS, infrastructure, or security-adjacent platforms).
- Strong PHP experience (LAMP or equivalent production backend environment).
- Demonstrated experience with secure file transfer protocols (SFTP, FTPS, FTPeS, SCP) and the ability to develop on top of them.
- Experience building integrations with external systems/APIs (auth, rate limits, webhooks, retries, pagination, data mapping).
- 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).
- Experience with Jira administration / analytics and building dashboards
- Additional languages (e.g., C++), or modernization patterns around legacy systems.
Benefits
- Health Care Plan (Employer paid Medical, Dental, & Vision)
- Retirement Plan (401k, IRA)
- Paid Time Off (Vacation, Sick time, & 12 company days)
- Training & Development
- Work From Home
- Reimbursement for mobile phone and home internet
- Company-issued computer and technology needed for your role
