We will go-to-market using AWS F2 FPGA instances and follow-on with an ASIC design that combines network aggregation with exchange functionality.\nPAX provides the fastest tick-to-trade and market data publication in the world, across all exchanges (e.g. faster than NYSE, Deutsche Börse, etc.).\nExchange integrated high frequency trading logic:\nThe PAX λ API provides traders with on-chip exchange integrated HFT decision logic. Using the λ API, traders can make markets or take arbitrage opportunities. The λ API enables traders to respond to market events the very instant the information is registered in the exchange matching engine.\nPAX business model:\nPAX sells access to its ultra-low latency λ API and offers trading otherwise for free. Existing exchanges typically offer rebates for liquidity providers (\"makers\") and charge fees to liquidity takers (the \"maker/taker\" fee structure). At PAX when λ and non-λ orders pair together, the free-tier order is given a cash rebate regardless of whether their order was characterized as making or taking. PAX is the first exchange to offer zero-fee trading and rebates for both making and taking.\nDeep dives on PAX market structure & technology:\nOn-exchange trading incentives with inherent price competition.\n\nPAX rebates & fees.\n\nPAX λ API.\n\nRelevant background:\nCandidates with experience in high frequency trading (HFT) or at an exchange are encouraged to apply.\nSkills:\nSystemVerilog\nFPGA or ASIC design experience\nRust and/or C++\nHFT\nProtobuf\nCuriosity and ability to learn\nPassion for trading and markets","description_format":"text","description_chars":1900,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto"],"lifecycle":[{"event":"open","at":"2026-09-25T17:18:06Z"}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":40,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-09-27T05:45:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/pax-markets-founding-hardware-engineer","json_url":"https://alion.io/job/pax-markets-founding-hardware-engineer.json","meta":{"generated_at":"2026-09-28T05:19:35Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3552,"day_limit":5000,"remaining_today":1448,"minute_limit":60,"resets_at":"2026-09-29T00:00:00Z"}}}
