SDK Integration Engineer - OESIS Framework

OPSWAT, a global leader in IT, OT, and ICS critical infrastructure cybersecurity, delivers an end-to-end platform that gives public and private sector organizations and enterprises the critical advantage needed to protect their complex networks, secure their devices, and ensure compliance. Over the last 20 years our commitment to innovative technology has earned the trust of more than 1,700 organizations, governments, and institutions globally, solidifying our role in protecting the world’s critical infrastructure and securing our way of life.

The Position

At OPSWAT, we’re building cutting-edge solutions that protect the world’s critical infrastructure. You will play a pivotal role in shaping the future of our OESIS Framework platform with cloud solution integrations. This role owns the architecture and implementation of the SDK's core integration layer — the code that talks to cloud-based Endpoint Device Management frameworks (such as: CrowdStrike Falcon, Microsoft Graph/Intune, JAMF Pro, and future device management APIs), and that packages the result as native binaries customers embed directly into their own cloud products. This person sets the technical direction the other roles build against the internal data contract, the auth-token interface, and the SDK's external API surface and versioning strategy.

What you will be doing

• Architect a unified, extensible integration framework that normalizes disparate vendor REST APIs (differing pagination models, rate limits, response schemas) into one consistent internal interface
• Design and build the SDK as native, cross-platform binaries (Windows/macOS/Linux) with a clean external API/header surface suitable for embedding into third-party customer products
• Build and maintain connector modules for Endpoint Device Management frameworks (such as CrowdStrike Falcon API, Microsoft Graph/Intune API, and JAMF Pro API), with an extension pattern for adding future platforms (Workspace ONE, Kandji, etc.)
• Implement resilient request handling per vendor: retry/backoff, rate-limit compliance, partial-failure recovery, and API version migrations
• Define SDK packaging, distribution, and versioning strategy (ABI/API compatibility, semantic versioning, installer/package formats)
• Own the SDK's public developer documentation and reference implementation for partner/customer integration teams
• Participate in leading technical design reviews across the small team; make final call on the internal data contract and auth-token interface shared with the Data and Auth engineers

What we need from you

• 3+ years professional software engineering experience, including 2+ years building or deeply integrating with REST APIs at production scale
• Strong C/C++, Rust, or Go experience building embeddable/native SDK binaries with cross-platform builds (Windows/macOS/Linux)
• Hands-on experience with at least one of: CrowdStrike Falcon API, Microsoft Graph API, or JAMF Pro API (or a comparable UEM/EDR/MDM API)
• Track record designing SDKs or libraries consumed by external developers or OEM partners — not just internal services
• Strong grasp of API contract design: semantic versioning, backward compatibility, deprecation strategy
• Experience with CI/CD pipelines producing multi-platform binary artifacts

It would be nice if you have

• Background in cybersecurity, endpoint security, or unified endpoint management (UEM)
• Familiarity with Zero Trust Network Access (ZTNA) and device posture or compliance
• Familiarity with Regulatory Compliance (PCI-DSS, SOX, HIPPA, etc.)
• Familiarity with vulnerability/patch management concepts (CVE, NVD, SCAP) — directly applicable to OESIS's existing domain
• Prior experience leading a small (2–4 person) engineering pod
