Work done at Furientis has meaning. About the Role The Chief of Staff works directly with the CEO and keeps the rest of the company moving by owning the operational work that sits across every function: fundraising, executive recruiting, customer engagement support, office operations, and the company systems a small team has not yet built. This role suits someone with experience at an early-stage startup, in defense, or in top-tier strategy work. You should be comfortable owning both the operational details that keep a small company moving and the higher-stakes decisions where the CEO benefits from a sharp second set of eyes. What You'll Do • Build and run the CEO's operating cadence: meetings, decision logs, action tracking, and follow-through across every team., • Drive fundraising operations through Series A: data room, investor updates, diligence response, scheduling, and materials., • Support Army and Navy customer engagement: prep briefings, manage follow-up, and coordinate program-office communications., • Own recruiting operations: pipeline hygiene, candidate scheduling, reference calls, offer logistics, and onboarding., • Own office operations: the LA HQ lease, IT contractor, cleaning, catering, and the other vendor contracts that keep the office running., • Build first-pass company systems: KPI reviews, planning templates, internal communications, and operating documentation., • Project-manage cross-functional initiatives that do not yet have a clear owner.Skills We're Hiring For, • 5+ years in a high-impact operator role: prior chief of staff, startup operations, or strategy consulting., • Track record of running cross-functional projects end-to-end with senior stakeholders., • Comfort moving between strategic decisions and the operational follow-through they require, often in the same day., • Sharp written communication.

We recruit engineers who internalize the warfighter's problems and bring deep mastery of the relevant technologies, without the institutional inertia that has slowed the legacy primes. Work done at Furientis has meaning. About the Role We are looking for a head of supply chain who will own the commercial side of every supplier relationship that touches our hardware. That covers motor hardware, avionics and seeker components, machined parts, raw materials, and capital equipment for the Mojave build line. Engineering owns the technical side: spec, qualification, DFM. You own the contract, the terms, the lead time, the cost, and the second-source strategy. You will report to the CEO and work directly with every engineering team. This is a hands-on role for the first year. Buying needs to happen this week and the long-term partnership work needs to happen at the same time. We are not staffed to wait on a process The most valuable thing you can do is take supply-chain bottleneck identification off the engineering team's plate. Engineers can name a bottleneck, but rarely have time to build the case for what to do about it. Is the right move to find a second source, redesign the part out, or pay the cost and move on. That work is yours. You set up shipping, receiving, and inventory and you own the function. You are not the person moving boxes day to day. That load is shared across the team. What You'll Do • Stand up the day-to-day purchasing function. Process today is as fast as possible; you own how that evolves with the company., • Own the commercial relationship with every supplier in the BOM. Engineering leads technical qualification and DFM; you are the buyer of record, the contract owner, and the escalation path on lead time and price., • Build long-term partnerships with the suppliers that matter most. Identify the few who deserve real time and energy and starve the rest., • Surface the supply chain bottlenecks the engineering team is hitting and put together the data so the team can see clearly whether a bottleneck should be second-sourced or designed out., • Own the BOM in NX and Teamcenter. Vendor codes, lead times, costs, second sources, ITAR status. The BOM is the single source of truth and it lives with you., • Negotiate commercial terms: pricing, lead time, payment terms, NRE, warranty. Work with outside counsel on the contract paper when needed., • Own ITAR, TAA, and Buy American flow-downs on supplier agreements. Defense-specific compliance is your problem, not engineering's., • Set up shipping, receiving, and inventory for the LA HQ and Mojave sites. Pick tools and processes simple enough that anyone on the team can run a shipment when needed.Skills We're Hiring For, • B.S. in a technical or business discipline (engineering, supply chain, operations, business)., • 8+ years owning the supply chain or strategic sourcing function for a hardware product that ships in low-to-medium volume., • Fluency with BOM management in PLM and ERP systems and with the data discipline a multi-tier hardware BOM requires., • Track record of negotiating with both small specialty suppliers and large defense or aerospace incumbents, and winning on terms and lead time., • Worked closely enough with hardware engineers to know when to push back on a design choice that is going to bite the supply chain six months out., • Fluency operating with agentic coding tools (Claude Code or equivalent). We expect operations to use AI for vendor research, contract review, BOM hygiene, and spend analysis the same way engineering uses it for design and analysis.Bonus Points For, • Defense, missile, or space hardware experience with the supplier base we will be buying from., • Stood up a supply chain function from scratch at a pre-Series-B hardware startup., • ITAR, TAA, Buy American, and FAR or DFARS flow-down experience on supplier agreements., • Hands-on experience sourcing energetic-material or other ITAR-controlled single-source items., • Capital equipment procurement for a build line or test facility.

We recruit engineers who internalize the warfighter's problems and bring deep mastery of the relevant technologies, without the institutional inertia that has slowed the legacy primes. Work done at Furientis has meaning. About the Team The Seeker Team builds the eyes and the targeting logic of our weapon system: a low-cost, mass-producible, multimodal missile seeker that leans on commercial supply chains where they outperform the defense legacy, with supply-chain security engineered in from day one. On a modern missile, the seeker is 40 to 60% of unit cost and often drives overly long delivery cycles; accordingly, the seeker team is at the tip of the spear for delivering value to our customers and to the taxpayer. Seeker design has exactly two real constraints: physics and mission. Supply chain, vendor lead time, qualification cost, "the way it's always been done": none of that stops us. We are a small, deeply technical team that drives capability through ingenuity and bias for action and ships hardware that flies. This is a wear-many-hats environment where you must be comfortable "building the airplane in flight" and stepping well outside your comfort zone; a narrowly scoped role with clean handoffs is not what this team offers. This is an AI-native team. Through fluent use of cutting-edge agentic coding tools, one engineer here consistently out-delivers a much larger conventional team. You will have opinions about where these tools help and where they do not, provide governance input, and build AI into your workflow from day one. About the Role You will execute the design, layout, bring-up, and qualification of the boards and SoMs that make our seeker run: FPA and image-sensor interface, GPU SoC / SoM carrier, high-speed digital and low-noise analog signal chains, shared-memory data plane between sensor and compute, power architecture from missile bus to detector bias rails, and the low-level firmware that brings it all up. This is a hands-on role for an engineer who can take a design from blank schematic to first-light bring-up to a low-latency CUDA pipeline running on an SoM in days, not months, and who thinks about manufacturability and second-source risk before the first prototype is built. What You'll Do • Develop and bring up mixed-signal boards centered on a GPU SoC or SoM (NVIDIA Jetson/Orin, Qualcomm, NXP, or similar): high-speed image-sensor interface, low-noise analog chain, power conversion, and missile-bus IO., • Architect and implement the high-speed image-sensor interface (LVDS, MIPI CSI-2, CameraLink, SLVS-EC, SerDes) end-to-end from sensor pinout to SoM ingest, including timing, signal integrity, and zero-copy DMA into GPU-accessible memory., • Stand up the on-board compute path on GPU SoCs: CUDA pipelines, TensorRT inference, and shared-memory/zero-copy data movement from capture to inference, hitting hard latency and jitter budgets., • Write low-level firmware, drivers, and bring-up tooling in Rust and Python: device-tree, sensor configuration, board diagnostics, automated bench tests, and the on-the-wire serialization layer (protobufs or equivalent)., • Execute schematic capture and PCB layout (Altium, Cadence, or KiCad), or partner with a layout designer when complexity warrants. Carrier-board design for the chosen SoM as required., • Drive the power chain from missile bus to FPA bias rails (sequencing, low-noise LDOs, switching regulation, transient response, isolation), with component selection that bakes in cost, lead-time, second-source, and rad-tolerance from day one., • Bring up boards on the bench (scope, logic analyzer, BERT, thermal imaging, rework iron) and chase low-latency, jitter-sensitive timing bugs to their physical root., • Execute EMI/EMC qualification per MIL-STD-461 and environmental qualification per MIL-STD-810; partner with mechanical on conformal coating, staking, thermal interfaces, and survivability., • Bake DFM and DFT in from the start: CM engagement, ICT/AOI, board-level test fixtures, and a clear path to volume.Skills We're Hiring For, • B.S. in Electrical Engineering, Computer Engineering, or related; M.S. preferred., • 4 to 6 years of mixed-signal hardware and firmware bring-up experience, with responsibility for at least one board (ideally with an SoM carrier) from schematic through bench validation., • Strong fundamentals across high-speed digital (signal integrity, controlled impedance), low-noise analog, and power conversion., • Hands-on with high-speed image-sensor interfaces (LVDS, MIPI CSI-2, CameraLink, SLVS-EC, or SerDes) end-to-end from sensor to compute. Non-negotiable., • Production CUDA experience: shipped real CUDA code, not dabbled. Reasons about kernels, memory layout, occupancy, streams, and host-device transfer cost; at the level needed to debug a stalled pipeline on an Orin., • SoMs and shared-memory ecosystems (Jetson family or equivalent): zero-copy and unified-memory patterns, getting sensor data into GPU-accessible memory without copies you can't afford., • Experience or strong willingness to work in Rust and Python for firmware, drivers, bring-up tooling, and low-latency host-side code., • Hands-on TensorRT: model conversion, calibration, plugin integration, and deployment into a real on-board inference pipeline., • Low-latency, jitter-sensitive applications: deterministic timing budgets, real-time scheduling, interrupt and DMA latency analysis., • Schematic and PCB tooling proficiency (Altium, Cadence, or KiCad) with practical layout judgment. Comfortable on the bench (scope, logic analyzer, soldering iron, rework)., • AI-native working style: daily use of agentic coding tools (Claude Code, Codex, OpenCode, Kilo, or similar) for firmware, test-bench scripts, component selection, and schematic/layout review.Bonus Points For, • NVIDIA PVA, Qualcomm Hexagon, OpenCL, or other heterogeneous-compute runtimes beyond CUDA., • Direct experience interfacing to IR detectors, focal-plane arrays, or ROICs (cooled or uncooled)., • Carrier-board design experience for a commercial SoM., • High-volume or DFM experience: walked a board through CM bring-up at production rate., • MIL-STD-461, MIL-STD-810, MIL-STD-1553, RS-422, or Ethernet-over-physical-layer qualification experience. Equal Opportunity & Export Compliance Furientis is an equal-opportunity employer.
