The engineer will also help build the future engineering team.

Own applied machine learning and LLM systems end to end, translating ambiguous business problems into datasets, models, evaluation frameworks, production pipelines, and deployed services. Build Python-based data and modeling infrastructure, improve LLM extraction and research agents, manage observability and reliability, and communicate technical tradeoffs with stakeholders. The role requires autonomous execution in a lean, onsite New York City engineering environment.

Designs, codes, deploys, and operates quantitative DeFi vault strategies across lending, yield aggregation, structured products, RWAs, and other protocols. Responsibilities include strategy research, backtesting, optimization, risk modeling, protocol due diligence, onchain execution, monitoring, incident response, and production ownership. The role partners on launches and participates in on-call coverage for live strategies managing customer capital.

Design, prototype, integrate, and debug custom electronics for an autonomous circuit-board fabrication platform. Responsibilities include circuit-board design, sensing and actuation systems, precision measurement, test fixtures, machine integration, low-level firmware, root-cause analysis, and end-to-end subsystem ownership. The role requires hands-on benchtop debugging, shipped hardware experience, cross-disciplinary mechanical intuition, and full-time on-site work in San Francisco within an intense founding environment.

Build the end-to-end architecture of an AI-powered software factory, including high-throughput telemetry capture, privacy pipelines, knowledge graphs, autonomous coding agents, and production deployment. Personally execute client workflow mapping and software delivery, then automate those processes for future deployments. The role requires strong product judgment, full-stack ownership, enterprise workflow optimization, and in-person collaboration in San Francisco.

Own the design, prototyping, testing, and validation of precision mechanical systems for automated process cells. Responsibilities include developing motion systems, fixtures, robotic handoffs, feed and clamping mechanisms, electrical test interfaces, and reliable high-cycle production equipment. The role requires rapid bench prototyping, empirical diagnostics, tolerance analysis, and close integration with electrical and software engineers. This is a fully onsite founding role in San Francisco requiring six-day workweeks.

Build and own the company’s enterprise risk management and information security functions. Lead SOC 2 and ISO 27001 compliance, security policies, ISMS development, incident response, business continuity and disaster recovery exercises, vendor and audit management, partner security due diligence, and security awareness training. Collaborate with engineering, product, legal, business development, and operations to maintain an audit-ready security posture.

Architect and build low-latency trading and clearing infrastructure in Rust for an institutional FX hedging venue. Own the technical roadmap, design risk management, margin, netting, and settlement engines, and uphold protocol security, reliability, and performance standards. The role requires deep Rust expertise, financial or trading infrastructure experience, AI-native development workflows, entrepreneurial ownership, and willingness to work on-site in New York City within an intense startup environment.

Lead design and implementation of high-performance agent runtimes, backend services, and self-hosted model/agent infrastructure. Build low-latency execution systems, real-time data pipelines, telemetry loops, CI/CD for zero-downtime deployments, and ensure fleet reliability on AWS/EKS.

Design, deploy, and maintain physical and cloud network infrastructure for a large-scale AI data platform. Implement IaC, virtualization, container orchestration, monitoring, and security to ensure scalable, reliable operations and integrate DevOps automation with engineering teams.
