Lead the Options Engineering team, enhance trading infrastructure, and evolve systematic options trading with a focus on automated systems and risk management.

The Engineering Lead for Options will oversee a team, improve trading systems, and support the platform's evolution, focusing on options trading.

The role involves developing and optimizing ultrasound imaging modes, collaborating on hardware and software integration, and ensuring high image quality across clinical applications.

Implement and audit software quality standards across programs, ensure compliance with contractual and process requirements, review designs and tests, support CMMI/AS9100 audits, collect/report software metrics, evaluate suppliers, and witness qualification and acceptance testing.

Lead a 10–20 person software team through the full SDLC in an Agile environment, delivering real-time/mission-critical software. Manage planning, execution, EVMS/Agile metrics, risks, cross-discipline collaboration, technical mentoring, and functional HR responsibilities.

Design and implement embedded firmware and low-level software for server BMCs and GPU/HPC platforms. Enhance OpenBMC, enable real-time telemetry of power/thermal sensors, debug low-level drivers and interfaces, validate hardware-firmware integration, and contribute to long-term firmware architecture for cluster reliability.

Design and implement Wi‑Fi 6 (802.11ax) and 802.11s mesh networking software for enterprise access points. Develop HMAC components, optimize throughput/latency/airtime, integrate on NXP-based Embedded Linux platforms, maintain hostapd/wpa_supplicant/mac80211, debug with packet captures, and collaborate with RF/firmware/QA teams for product releases.

The Senior HPC Architect role involves deploying large-scale GPU compute clusters, optimizing system administration, and collaborating with researchers on HPC and AI solutions.

Own and scale the search, indexing, and data-scanning infrastructure for petabyte-scale data. Optimize hybrid lexical and vector retrieval for sub-second latency, design cost-effective hot/warm/cold data tiering and massive asynchronous scans, drive down latency and cost, and provide technical leadership for resilient, highly available indexing and retrieval systems.

Develop, profile, and optimize high-performance C#/.NET software and desktop UIs (WPF/MVVM, Blazor). Apply CS fundamentals, implement CRUD/gRPC services, operate in CI/CD and version-controlled environments, follow secure coding/DoD standards, produce technical documentation, reverse-engineer legacy code, and support system modeling/simulation for defense programs on-site.
