Our SEC-registered broker-dealer network carries a digital asset through its entire life, from issuance and distribution to qualified custody, correspondent clearing, and secondary market trading, all within U.S. securities law.\nThat work has put us first more than once. We became the first SEC-registered special purpose broker-dealer, and the first to trade ETH inside a traditional brokerage account. Those milestones rest on systems our engineers build every day, and we are searching for engineers like you to help us grow our team.\nRole:-\nBlockchain Engineer 2 - Full time W2\nSalary Range:-\n$130,000 - $165,000\nOverview:-\nAs a Blockchain Engineer 2, you take ownership of a whole feature once an epic is agreed on. Epics come from the Architect and CTO, but they are shaped in team brainstorms where you are expected to bring a view, including what is happening across the blockchain and cryptography landscape and how it should change our approach. Once we have consensus, you break the work into pieces the team can pick up, get it ready to build, guide it through to release, and keep stakeholders honestly informed along the way. You will work with the Architect on technical design, with guidance from senior engineers as you grow into that part of the job.\nWe are a specialist team. Other teams depend on us for custody contracts, transaction signing and orchestration, and the key management that ties them together, work they cannot do themselves, so our output is measured by how well it serves those teams and the customers behind them, not by how much of it you shipped. When something is not moving, we expect you to say so early and come with options.\nOur engineering team is fully remote.\nResponsibilities:-\nBuild and maintain secure and optimized blockchain applications\nOwn epics end to end, from story writing and pointing through delivery and release\nBuild across many different languages taking on the large, complex problems in your team's scope\nReport progress on your epic regularly and accurately, and raise risks before they become surprises\nPartner with senior engineers on technical design, architecture decisions, and future epics\nDemonstrate a passion for learning, building, and constantly improving cutting-edge applications\nCommunicate often to encourage tight and quick feedback loops and remove potential blockers\nUse AI coding tools as a default part of your workflow, and review what they produce with the same rigor you would apply to your own code\nReview teammates' code in a way that catches design concerns, edge cases, and test gaps\nWork directly with neighboring systems throughout delivery, not just at the handoff\nInvestigate and resolve issues found in QA, UAT, and production\nQualifications:-\n3 or more years of professional software engineering experience building and shipping production software\nStrong blockchain fundamental knowledge including in-depth knowledge of top chains (i.e. Bitcoin and Ethereum)\nFamiliarity with basic cryptography commonly utilized by blockchains\nStrong administrative/organizational skills (ability to effectively prioritize, manage time, and meet deadlines on multiple projects)\nAutomated testing as a habit rather than an afterthought\nHands-on experience with AI coding assistants, plus the judgment to know when their output is wrong\nClear written communication with a strong command of the English language, which matters more on a fully remote team\nAble to reason through technical disagreements with evidence, and to update your view when the evidence shifts\nAuthorized to work in the U.S. or Canada\nAble to pass a comprehensive background check, which is required for this role\n Nice to have:-\nExperience mentoring or onboarding other engineers\nBackground in finance, brokerage, trading, or custody\nExposure to regulated environments and the audit trails they require\nExperience with Jira, Confluence, or similar\n How we work:-\nFully remote engineering. We work together in real time, with overlapping hours for pairing, reviews, and ceremonies.\nAI-forward. We actively champion AI and tooling that ships customer value faster without giving up quality. Engineers at every level are expected to use these tools well and to bring what they find back to the team.\nFeedback is specific and regular. Quarterly reviews, weekly 1:1s, and a candid conversation when something is not landing, not a surprise at year end.\n Benefits:-\nHealth, dental, vision, disability, and life insurance\nStock options\nCompetitive vacation time, paid sick days, and time off for observed federal holidays\nEquipment provided\n Prometheum is an equal opportunity employer.","description_format":"text","description_chars":4740,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Life insurance","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Cryptocurrencies","Asset Tokenization","Stock Exchanges & Market Infrastructure"],"lifecycle":[{"event":"open","at":"2026-10-14T08:57:02Z"}],"visa":[],"liveness":{"score":85,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":0.945,"age_days":4,"expected_fill_days":7,"reasons":["conf:3","velocity","win:mid"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/prometheum-blockchain-engineer-2-prometheum","json_url":"https://alion.io/job/prometheum-blockchain-engineer-2-prometheum.json","meta":{"generated_at":"2026-10-19T10:18:17Z","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":7294,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":3909143},"rest":"https://alion.io/mcp/rest/get_company?id=3909143"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprometheum-blockchain-engineer-2-prometheum"},{"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%2Fprometheum-blockchain-engineer-2-prometheum"},{"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%2Fprometheum-blockchain-engineer-2-prometheum"},{"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/prometheum-blockchain-engineer-2-prometheum\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprometheum-blockchain-engineer-2-prometheum"}]}
