• Define and maintain target-state architecture for IT and OT infrastructure, including networks, servers, virtualization, cloud platforms, identity, and supporting services. • Design secure, resilient, and scalable architectures for enterprise and plant environments, supporting availability, performance, and operational safety requirements. • Develop and maintain architecture standards, patterns, and reference designs for IT and OT environments. • Partner with enterprise architecture, application, and OT teams to ensure consistent adoption of standards and integration across domains. • Collaborate with OT teams to design and secure infrastructure supporting ICS, DCS, PLCs, SCADA, and plant network environments. • Support secure IT/OT convergence while respecting operational constraints, safety, and uptime requirements. • Ensure OT infrastructure designs align with industry best practices and regulatory expectations for industrial environments. • Embed security-by-design principles into all IT and OT infrastructure architectures. • Define and enforce cybersecurity architecture controls aligned to frameworks such as NIST CSF, NIST 800-53/82, IEC 62443, and Zero Trust principles. • Partner with cybersecurity teams to design controls for network segmentation, identity and access management, monitoring, logging, vulnerability management, and incident response. • Participate in architecture and security risk assessments; identify gaps and drive remediation through design and engineering standards. • Ensure infrastructure solutions comply with corporate policies, cybersecurity standards, and regulatory requirements. • Support audits, risk assessments, and tabletop exercises by providing architectural insight and documentation. • Maintain accurate architecture documentation, diagrams, and decision records. • Serve as a trusted technical advisor to IT, OT, cybersecurity, and business stakeholders. • Provide architectural guidance during project intake, design reviews, and technology evaluations. • Mentor infrastructure engineers and encourage knowledge transfer to reduce key-person dependencies. • Evaluate emerging technologies and recommend improvements to enhance security, resilience, and cost efficiency.

• Own the architecture and scalability of our backend systems, including Postgres, job queues, OpenSearch, Redis, and the data pipelines that move events between customer integrations and our product. • Scale our infrastructure from tens of thousands of jobs to orders of magnitude more, ahead of customer demand rather than behind it. • Make the tradeoffs that determine whether infra work takes weeks or months. • Set the bar for reliability, observability, and operational excellence. • Partner with Will on architecture decisions and with product engineers on the systems they build on top of yours.

• Infrastructure management and optimization (AWS, MongoDB, infrastructure as code) • Platform capabilities including but not limited to authentication, authorization, entitlement, AI inference • CI/CD pipeline improvements and build tooling • Worker queue management (BullMQ) and API development (tRPC) • Developer experience improvements and tooling • Monitoring and observability (Datadog) • Service reliability and performance optimization

• Guide complex initiatives from initial requirements gathering and robust system design to deployment, effectively evaluating dependent technologies and collaborating closely with stakeholders. • Build scalable data infrastructure and shape the developer experience, tackling projects such as owning data cataloging, versioning, and lineage to support seamless research and production workflows. • Provide technical guidance to both engineering and research staff, fostering a supportive environment that accelerates the growth of your teammates.
