We hire for distributed-systems depth and proven ability to ramp fast on unfamiliar deep tech. If you’ve spent years in Ethereum L2s or L1 clients, wonderful, but the bar is ramp speed, not resume keywords. If your background is trading systems, consensus, or low-latency backend infrastructure and you can learn the Ethereum-specific parts quickly, we want to talk.\n\nWhat you’ll build and own:\n\nThe Engine (Rust): L2 and L1 preconfs (preconfirmations), parallel block building, and blocksapce configuration.\nCross-chain settlement paths: vault contracts custodying capital on Ethereum L1, execution on the L2, and relayer services with confirmed-send semantics, serialized nonce management, and crash-restart recovery.\nOn-chain infrastructure: Rollup Contracts and messaging between L1 and L2.\nOff-chain services in TypeScript (Node 20, viem): high-cadence pricers signing EIP-712 payloads, cross-chain relayers, risk monitors, keepers, and quoting bots, engineered for restarts, nonce races, and stale-data edges.\nTEE attestation infrastructure: hardware attestation verification (Intel TDX DCAP, AMD SEV-SNP) implemented in both Solidity and Rust, kept in lockstep by cross-language parity tests.\nZK Proofs: Zero knowledge proofs\nThe test surface that keeps it honest: Foundry fuzz and invariant suites, adversarial regression tests, and live-testnet E2E harnesses.\n\nYou’ll pick a primary layer; you’re expected to read across all of them.\n\nHow we work:\n\nSecurity is built into the process: External audits, invariant gates in CI, and honest internal tracking of what’s production-grade versus simulated.\nShip to a live network: We deploy continuously. Your work can be running in production within days, not quarters, and is read by client-team and rollup-stack peers, not just your standup.\nSmall, senior team: Direct ownership, written decision-making (ADRs), and minimal process overhead.\n\nWhat we offer:\n\nCompetitive compensation: Salary + token/equity.\n\nRemote-friendly: Work from where you’re most effective, with flexibility across time zones.\n\nMeaningful ownership: Join a small, senior team where your work directly shapes the product, architecture, and network.\nHigh-impact work: Build infrastructure that ships to a live network and is used in production, not prototypes that sit on a roadmap.\nRoom to grow: Take ownership beyond your initial scope as the team and network scale.\nLow bureaucracy: Direct access to the team, fast decisions, and minimal organizational overhead.\n\nHow to apply:\n\nEmail  with:\n\nYour GitHub username and the hardest system you’ve built, a repo, design doc, or postmortem; and\n3–5 sentences on the nastiest failure mode you’ve personally debugged in a distributed system.\n\nWe read code before CVs. We reply to every application that includes both. But do include your resume as a PDF. No cover letter needed. Our docs are public at http://docs.puffer.fi. We’d rather you read them and show up skeptical than judge us by this posting.\n\nAbout Puffer & Puffer UniFi\n\nPuffer builds Ethereum-native infrastructure: the pufETH liquid restaking protocol, the UniFi based rollup, and the UniFi Preconf. UniFi is an OP-Stack rollup sequenced by Ethereum’s own validators, pairing L1-grade neutrality with real-time UX: sub-10ms execution preconfirmations backed by restaked ETH, ~10-second withdrawals via a TEE multi-prover (Intel TDX + AMD SEV) instead of a 7-day dispute window, and same-slot L1⇔L2 composability through the Signal Service. Sequencing value flows back to Ethereum, not to us.\n\nWe’re backed by Brevan Howard Digital, Electric Capital, Coinbase Ventures, Yzi Labs, Kraken Ventures, Franklin Templeton, and F-Prime (Fidelity), plus grants from the Ethereum Foundation and EigenLayer.\nRequirements$13","description_format":"text","description_chars":3952,"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":["Equity"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Cryptocurrencies"],"lifecycle":[{"event":"open","at":"2026-10-14T05:34:58Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.539,"p_room":0.45,"age_days":52,"expected_fill_days":29,"reasons":["seen:52","win:tail"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/puffer-finance-senior-protocol-engineer","json_url":"https://alion.io/job/puffer-finance-senior-protocol-engineer.json","meta":{"generated_at":"2026-10-16T08:31:18Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6448,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":175813},"rest":"https://alion.io/mcp/rest/get_company?id=175813"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpuffer-finance-senior-protocol-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fpuffer-finance-senior-protocol-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fpuffer-finance-senior-protocol-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/puffer-finance-senior-protocol-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpuffer-finance-senior-protocol-engineer"}]}
