Own projects end to end, make product trade-offs, collaborate with customers and product managers, improve observability and reliability, support on-call operations, and use AI coding agents safely. The role requires systems thinking across containers, registries, build infrastructure, and customer clusters in a remote-first environment.

The Senior Product Engineer designs and supports industrial water-control products, creates CAD drawings, bills of materials, and process sheets, and leads engineering improvement projects. Responsibilities include manufacturing and shop-floor support, product testing, quality and ISO compliance, approval-agency coordination, customer and internal technical support, cost-reduction initiatives, and Lean manufacturing programs. The role also mentors product engineers and collaborates on product development, maintenance, testing, and manufacturing improvements.

Designs and documents multilayer PCBs, schematics, layouts, electrical systems, and mechanical drawings using Altium Designer and CAD tools. Converts OrCAD designs, creates 3D models, performs design calculations, maintains drawing databases, supports parts procurement and fabrication, applies GD&T and IPC standards, and mentors drafters and students. The role is onsite in Batavia and requires compliance with safety, background screening, and HSPD-12 credentialing requirements.

Designs, installs, secures, maintains, and supports enterprise servers, virtualization, storage, networking, firewalls, VPNs, wireless infrastructure, and Microsoft platforms. The role manages complex infrastructure projects, monitoring, configuration management, documentation, disaster recovery, vendor relationships, and technical troubleshooting. It provides after-hours emergency support, mentors team members, evaluates technologies, and occasionally travels for subsidiary support or training.

Develop and validate silicon photonics optical modules for optical connectivity applications. Lead prototype performance demonstrations, create validation platforms, manage link budgets and system models, coordinate manufacturing test requirements, and perform failure analysis and debugging. Collaborate cross-functionally while characterizing lasers and photonic components using benchtop equipment and data-analysis tools.

Build secure, production-critical payment infrastructure for AI agent transactions. Design Python and FastAPI services, APIs, domain models, provisioning workflows, and cryptographic payment flows. Ensure scalability, reliability, observability, security, and comprehensive testing. Use Kubernetes, AWS, Terraform, and GitOps to automate infrastructure. Collaborate with product, security, infrastructure, platform, and card-network partners while applying AI-assisted engineering practices.

Build and operate platform-wide logging, metrics, tracing, dashboards, and alerting infrastructure. Develop Java and Python libraries, manage Terraform-based telemetry systems, improve observability architecture, tune alerts, support incident response, participate in on-call rotations, and maintain FedRAMP-compliant documentation and data handling.

Leads aerospace composite manufacturing engineering across tooling, fixtures, process definition, production systems, and inspection methods. Develops work instructions, shop aids, process documentation, and manufacturing improvements; interprets drawings and specifications; supports root-cause investigations, corrective actions, customer reviews, and technical programs. Provides technical leadership and mentoring while applying expertise in composites, bonding, structural assembly, CNC machining, laser tracker and CMM inspection, and CAD-based tool design.
