Senior Staff Software Engineer — SaaS Platform & Cross-Product Architecture

About Us

At Netwrix, our mission is to revolutionize data security by placing identity at the core - providing unparalleled visibility and control. Engineered and supported by over 900 highly talented, motivated employees and hundreds of trusted partners in nearly every geography, Netwrix solutions are relied upon daily by security professionals across more than 13,500 organizations in over 100 countries around the world.

Over the past two decades, Netwrix has expanded its market presence through innovation, organic growth, and strategic acquisitions, and are proud to be backed by renowned private equity firms, TA Associates and Centerbridge Partners. Netwrix maintains a global presence, fostering a remote-first work environment while encouraging and facilitating frequent face-to-face interaction with colleagues, customers, and partners.

This is a hybrid role with visits to our Kraków office.

What you'll do:

• Own technical decision-making for the teams you support: evaluate technology options, run POCs and benchmarks, and make evidence-based recommendations on frameworks, datastores, and infrastructure —including partition strategies, migration plans, and performance validation at SaaS scale
• Shape platform-level architecture: Kubernetes (AKS) deployment topology, Kafka-based messaging, durable workflow orchestration, and multi-tenant data models
• Serve as an embedded architecture partner for .NET product teams: review technical designs, code, author/critique RFCs, guide teams through scalability and cloud-readiness problems, and help converge products toward shared platform standards
• Mentor engineers across teams and raise the bar on engineering standards (GitOps, golden pipelines, observability, supply-chain security)
• Assess established on-premises products for scaling, performance, resiliency, code quality, technology choices, supported environments, interoperability, security, and third-party dependencies, and define a realistic migration path to SaaS that does not disrupt on-premises delivery
• Partner with Product Management, Support, and Professional Services to ground architecture recommendations in real customer and field issues, and review findings with those teams before publishing
• Produce architecture artifacts — C4 diagrams, RFCs, design reviews, benchmarks — and present trade-offs to engineering leadership
• Design, build, and improve microservices and backend systems for the SaaS platform using related technologies such as Java, Spring Boot, JDK 21+, and .NET. Follow sound cloud-native development principles, including API-first design, resilience patterns, and comprehensive unit, integration, and performance testing.
• Turn recurring solutions into shared libraries, tooling, and examples that other teams can adopt.
• Use AI-assisted development tools for coding, testing, and design exploration. Review generated code with the same care as any other contribution, including correctness, security, and maintainability.

Skills and Experience

• 10+ years in software engineering, with a track record of technical leadership
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field — or equivalent practical experience
• Hands-on expertise in Java (Spring ecosystem)
• Hands-on experience with C#/.NET and sound architectural judgment, with the ability to review designs and code, provide design guidance, and help product teams address scalability and cloud-readiness challenges.
• Working familiarity with Active Directory and Entra ID: domain services, LDAP, authentication protocols, and directory data models, with the appetite to go deeper
• Comfortable reasoning about Windows-centric on-premises products (agents, domain controllers, customer-installed footprints) and the constraints of dual on-premises and SaaS delivery
• Comfortable with distributed-data fundamentals: partitioning, consistency trade-offs, high-volume ingestion/ETL, query performance tuning; hands-on with a relational database at scale (PostgreSQL, SQL Server or similar), plus exposure to at least one analytical or NoSQL store
• Event-driven architecture experience (Kafka, RabbitMQ or similar), API-first design, and modern resilience/observability practices
• Good documentation skills — comfortable producing RFCs and design docs and influencing teams you don't manage

Nice to have

• Go, Azure, workflow engines (e.g. Temporal)
• Experience with Spring Reactive
• Exposure to identity security, such as ITDR, privileged access management, or identity governance
