Share this job
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.
About the Role
The CTO Intelligence Hub is OPSWAT’s internal data platform; a fleet of 20+ containerised applications running on AWS EC2 that deliver AI adoption analytics, financial intelligence, customer health scoring, sales leaderboards, and content generation to OPSWAT leadership and 590+ engineers worldwide. You will own the infrastructure layer that keeps this platform reliable, secure, and scalable.
This is a hands-on individual-contributor role. You will be the sole infrastructure owner on day one, working closely with the CTO and one AI Platform Architect to operationalise and evolve the system.
What You Will Own
- AWS infrastructure: EC2 instances (eu-north-1), S3 buckets, IAM roles, SSM-based remote access (no SSH), security group allowlists across 8 global offices
- Container orchestration: Docker Compose fleet of 20+ services with sequential startup chains, health monitoring, auto-rollback, and OOM prevention on memory-constrained instances
- CI/CD pipeline: GitHub Actions workflows (centralized deploy-app.yml), S3 artifact rotation, per-service smart change detection, post-deploy health checks
- Reverse proxy & SSO: nginx routing, Cloudflare SSL termination, OAuth2 Proxy backed by Azure AD for single sign-on across all internal apps
- Credential & secrets management: OAuth token lifecycle (token-proxy auto-refresh), GitHub org secrets, PAT rotation, SSM Parameter Store, per-app .env files
- Data pipeline operations: EC2 #3 (Fabric → Parquet → S3), daily cron jobs, MSAL token refresh, lockfile and resume logic
- Observability & incident response: health monitor (15-min cron), watchdog deep-checks, Telegram alerting, EC2 reboot recovery, Docker mount-corruption recovery
- Security posture: network-level access controls, credential hygiene, OPSEC between corporate and personal identities
You Will Be a Strong Fit If You Have
- 3–6 years hands-on AWS experience (EC2, S3, IAM, SSM — not just console clicks)
- Solid Docker and Docker Compose skills; you debug failed container starts at 2 am without fear
- GitHub Actions: writing and maintaining multi-job workflows with secrets, artifacts, and matrix builds
- Linux system administration (Ubuntu): cron, systemd, disk management, process investigation
- Python scripting for ops tasks (deployment scripts, health checks, API automation)
- nginx configuration: upstream proxying, path-based routing, SSL
- A security-first mindset: you default to least-privilege and always ask “what happens if this leaks?”
Nice to Have
- Experience with Cloudflare (proxying, SSL, DNS management)
- Azure AD or OAuth2 Proxy familiarity
- PostgreSQL administration
- Experience operating ML/AI inference workloads
- GitHub App development (JWT-based installation tokens)
- Familiarity with Microsoft Fabric or Azure data services

- Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI (or related UI frameworks), C#, XAML, and — when needed — C++.
- Define and enforce best-practices for Windows desktop development across the codebase: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
- Drive accessibility efforts: integrate and validate support for accessibility APIs (e.g. Microsoft UI Automation or other relevant Windows accessibility frameworks), ensure UI controls, focus management, keyboard navigation, screen-reader support, and usability for users with disabilities.
- Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and long-term roadmap for the Windows platform.
- Take ownership of full lifecycle of features: conception → design → implementation → testing → release → maintenance. Ensure quality, reliability, and consistency across releases.
- Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems — and propose robust architectural or design solutions.
Required:
- 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
- Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.
- Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability.
- Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software.
- Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant).
- Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
- Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
- A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.
Preferred / Bonus:
- Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
- Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
- Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
- Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
- Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
- Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.
What we offer
- A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
- A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
- Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
- Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.
- A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.
