As enterprises scale AI agents across the organization, Onyx gives them the visibility, governance, and operational control to understand what agents exist, what they do, and what risks they introduce. We’re a fast-moving team helping the world’s largest companies adopt AI safely.\nAbout the Role:\nAs a Senior Customer Engineer, you'll deliver Onyx's professional services: engagements that take customers past what the platform does on its own and leave them with a result they can measure. You'll report to the Director of Customer Engineering as one of the first hires on a new team.\nOur largest customers bring us problems the product alone doesn't solve. Detections that need tuning to their environment. Agents they built themselves and need reviewed before launch. Finance asking what AI is costing them, and auditors asking for evidence of AI controls. That's the work we see today, alongside custom deployments, integrations, and automation for needs we haven't seen yet.\nWe're still defining which services we offer, and you'll help decide. Expect the work to change as we learn what customers need most. We're looking for a hands-on security practitioner who likes solving new problems and turning the answers into something repeatable.\nWhat You'll Do:\nDeliver to a finished result. Take each engagement from kickoff to customer sign-off, with a clear definition of done and an outcome the customer can measure.\nTune controls to each customer. Use real alert data to cut noise, build policies and detections that fit their environment, and hand them off documented so the customer can keep them tuned.\nReview what customers build. Assess the AI agents and MCP servers customers build themselves, and deliver findings and a remediation plan before they go live.\nAnswer the hard questions. Build the analyses and evidence customers' finance and compliance teams need - where their AI spend goes, and how their controls map to the frameworks they're audited against.\nBuild what doesn't exist yet, and make it repeatable. Take on custom deployments, integrations, and automation; turn what you build into tooling, templates, and methods the team reuses; and help shape which services Onyx offers and what \"done\" looks like for each.\nRequirements\nWhat You Bring:\n5+ years in hands-on technical roles (professional services, security consulting, solutions or customer engineering, or similar) with enterprise customers, including taking scoped projects from start to finish.\nA security background, such as detection engineering, application security, security architecture, or cloud security.\nStrong scripting skills (Python or similar) and comfort with REST APIs, cloud platforms (AWS/Azure/GCP), and querying and analyzing logs and data (SQL or log query languages).\nClear technical writing and communication, including findings and reports customers can act on.\nComfort with ambiguity and an interest in building a new function.\nNice to Have:\nExperience with AI security - testing LLM applications, agents, or MCP servers - and with AI/ML platforms, LLM tooling, or agent frameworks.\nBackground in SIEM or SOC work.\nFamiliarity with security and AI governance frameworks (e.g., SOC 2, ISO 27001, NIST AI RMF, EU AI Act).\nExposure to cloud or AI cost analysis.\nRelevant certifications (e.g., GIAC, cloud provider certifications).\nJob Benefits:\nRemote work model\nHealth insurance and wellness benefits\nEquity participation\nCompensation Disclosure\nWe offer a competitive compensation package that includes base salary, equity, and performance-based incentives. Compensation will be determined based on experience, location, and the scope of the role.\nEqual Opportunity Statement\nOnyx is an equal opportunity employer. We value diverse perspectives and are committed to building an inclusive environment for all employees.","description_format":"text","description_chars":3904,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Health insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity AI","AI Governance & Compliance"],"lifecycle":[{"event":"open","at":"2026-10-23T04:52:53Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.426,"p_room":0.35,"age_days":30,"expected_fill_days":7,"reasons":["conf:2","velocity","win:tail"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/onyx-senior-customer-engineer","json_url":"https://alion.io/job/onyx-senior-customer-engineer.json","meta":{"generated_at":"2026-10-29T13:43:57Z","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":20609,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":1913430},"rest":"https://alion.io/mcp/rest/get_company?id=1913430"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fonyx-senior-customer-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%2Fonyx-senior-customer-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%2Fonyx-senior-customer-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/onyx-senior-customer-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fonyx-senior-customer-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3133658}},{"tool":"search_jobs","arguments":{"company":"onyx.security","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3133658},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
