Join a team of passionate, collaborative, and inventive professionals at Staples Digital Solutions. We are customer-centric, agile, and results-oriented problem solvers who anticipate the needs of our business partners and deliver reliable technology services. Our culture values intellectual curiosity, teamwork, and adaptability, creating an environment where technology advancements drive the company forward.

As a Senior Private Cloud Infrastructure Developer, you will play a pivotal role in designing, building, and evolving internal private cloud and infrastructure platforms at enterprise scale. You will deliver secure, resilient, and observable .NET services and automation that support thousands of users and critical systems, partnering with architects, network engineering, security, and operations teams to drive impactful, production-ready solutions. Operating with significant autonomy, this role applies deep expertise in platform engineering, networking, and enterprise systems to develop solutions that perform reliably across complex corporate networks, security controls, and compliance requirements. The role partners closely with solution architects, network engineering, security, and operations teams to deliver pragmatic, production‑ready solutions that balance speed, safety, and long‑term maintainability.

What you’ll be doing:

Platform & Service Engineering:

• Design, build, and maintain production‑grade .NET (C#) services, APIs, and background workers (REST, gRPC, asynchronous processing) that integrate with enterprise systems such as identity platforms, networking services, secrets management, CMDBs, and ticketing systems.

• Develop internal platforms, reusable libraries, SDKs, CLIs, and templates that enable consistent, scalable delivery across engineering teams.

• Apply modern software engineering patterns including dependency injection, configuration management, async/await, structured error handling, and API versioning

Networking‑Aware Development:

• Build software that operates reliably across enterprise network environments, accounting for proxies, firewalls, NAT, load balancers, DNS behavior, and latency constraints.

• Implement secure transport mechanisms including TLS/mTLS, certificate handling, and diagnostics for network‑related failures.

Reliability, Observability & Operations:

• Instrument services using OpenTelemetry and related tooling to produce actionable metrics, logs, and distributed traces.

• Define and implement health checks, SLIs/SLOs, retries, timeouts, circuit breakers, and resilience patterns.

• Participate in on‑call rotations, incident response, root‑cause analysis, and post‑incident reviews; drive durable fixes rather than temporary mitigations.

• Perform capacity planning, performance tuning, and operational readiness reviews.

Security & Compliance:

• Apply security‑by‑default principles including least‑privilege access, secure service‑to‑service authentication, and safe secret handling (e.g., CyberArk, Azure Key Vault).

• Implement OAuth2/OIDC authentication flows and service principal‑based access models.

• Ensure solutions align with enterprise compliance requirements (e.g., SOX, PCI, ISO‑aligned controls) and change management processes.

Infrastructure Automation & Delivery:

• Contribute to CI/CD pipelines using Git‑based workflows (e.g., Azure DevOps, GitHub Actions).

• Develop and maintain infrastructure‑as‑code using Terraform, Bicep, or ARM templates to enable repeatable, auditable deployments across environments.

• Support multi‑environment promotion strategies and operational readiness for production releases

Documentation & Knowledge Sharing:

• Produce clear and actionable technical documentation including runbooks, architecture decision records (ADRs), and developer guides.

• Mentor and coach less experienced engineers, promoting best practices in platform, reliability, and secure software design

What you bring to the table:

• You have strong systems thinking focused on operability, maintainability, and security. 

• Your pragmatic approach balances ideal design with real-world enterprise needs. 

• You demonstrate ownership, accountability, and excellent communication skills, collaborating and influencing across teams even without formal authority.

What’s needed - Basic Qualifications:

• Bachelor’s Degree in Computer Science, Engineering, or related field, or equivalent experience

• 8+ years of hands-on experience developing production .NET (C#) services.

• Experience building and operating REST or gRPC APIs at scale.

• Strong knowledge of networking fundamentals, CI/CD pipelines using Git-based workflows, .NET Core Entity Framework (EF Core), and SQL database design.

What’s needed - Preferred Qualifications:

• 10+ years in enterprise software or platform engineering.

• Experience developing internal developer platforms, reusable libraries and golden paths.

• Operating services on both Windows and Linux.

• Proven experience with observability tools, integrating with databases (SQL Server or Postgres) and enterprise messaging platforms.

• Experience with enterprise PKI, certificate automation, and rotation

• Experience with infrastructure-as-code (IaC) tools (Terraform, Bicep, ARM)

• Hands-on experience with performance profiling, capacity planning, and resilience patterns.

• Familiarity with Zero Trust architectures, network segmentation, containers, Kubernetes, and SRE practices.

We Offer:

• Inclusive culture with associate-led Business Resource Groups
• 22 days of PTO and Holiday Schedule (7 observed paid holidays + 1 floating holiday)
• Online and Retail Discounts, Company Match 401(k), Physical and Mental Health Wellness programs, and more!
