Signal 1’s first product, the AI Management System (AIMS), gives health system leaders visibility and control across their growing AI portfolios. AIMS offers comprehensive oversight of predictive and generative AI applications and introduces guardrails to mitigate downside risks. It sets the standard for Responsible AI in healthcare. Purpose-built for healthcare and informed by years of experience managing AI at scale in other industries, Signal 1 empowers healthcare organizations to translate innovation into real clinical, operational, and financial outcomes.\nSignal 1 is a 30-person, well-funded and rapidly growing startup with strong product market fit and deployments at a growing number of top-20US health systems.\nWe are looking for a Security Engineer to join our Engineering Team. You will:\nSupport end-to-end security architecture across all domains (IAM, infrastructure security, application security, cyber defense, and data security), ensuring controls are consistent, defensible, and right-sized for a fast-moving healthcare AI platform.\nDesign and implement Azure-native security solutions using the full Microsoft security stack: Entra ID, Defender for Cloud, Microsoft Sentinel, Defender for Endpoint, Purview, and Azure Policy, across both fully cloud-based and hybrid infrastructure environments.\nSupport and collaborate on GRC programs across the full compliance lifecycle, contributing to control mapping, evidence collection, and audit readiness for SOC 2 Type II, HIPAA, and potentially other frameworks as the business evolves.\nPartner with Engineering, ML, and Infrastructure teams to embed security throughout the SDLC, from threat modeling and architecture review through to CI/CD pipeline hardening, secrets management, and production monitoring.\nBuild and operationalize security monitoring, alerting, and incident response capabilities, identifyingdetection gaps and closing them with tooling, process, and cross-team coordination.\nChampion product security across the AIMS platform, conducting security design reviews, threat modeling, and vulnerability assessments on new and existing features, and working closely with product and engineering teams to ensure security is built in from the start, not bolted on.\nBring an open mindset to the role, willing to roll up your sleeves and contribute to broader engineering and infrastructure initiatives outside of pure security work when the team needs it.\nRequired Qualifications\nBachelor’s degree in computer science/engineeringor equivalent practical experience.\n5+ years of experience in security engineering, with deep, hands-on expertisein Microsoft Azure security architecture and the Microsoft security product ecosystem.\nTechnically strong across all security domains (IAM, infrastructure, application security, cyber defense, and data protection), with the architectural depth to design solutions from first principles, not just operateexisting ones.\nYou see the big picture. You understand how security decisions affect product velocity, customer trust, and business outcomes, and you can translate technical risk into language that resonates with executives, customers, and cross-functional partners.\nComfortable securing both fully cloud-native and hybrid environments, with a strong understanding of the trust boundaries and control differences between the two.\nExperienced operating in highly regulated environments, with direct involvement in SOC 2 Type II, HIPAA, or equivalent compliance programs.\nYou thrive in fast-paced, high-ambiguity environments. You can triage competing priorities, move quickly without cutting corners, and build durable solutions under startup constraints.\nProactive and curious by nature. You don’twait to be pointed at problems, you go looking for them, and you bring genuine enthusiasm for learning new domains, tools, and threat landscapes.\nStrong communicationskills with the ability to engage engineering teams, executive stakeholders, and external customers including hospital security and compliance teams.\nPreferred Qualifications\nRelevant certifications: CISSP, AZ-500 (Azure Security Engineer), or OSCP.\nFluent with AI coding and productivity tools, using them as a force multiplier in your daily work, not as an afterthought.\nExperience with Kubernetes security, infrastructure-as-code (Terraform/Bicep), and securing CI/CD pipelines in Azure DevOps or GitHub Actions.\nFamiliarity with healthcare data standards and regulations (HIPAA, PHIPA) or prior experience securing systems in healthcare, finance, or other regulated industries.\nExposure to AI/ML security considerations (model access controls, data pipeline integrity, LLM threat surfaces, or agent security) is a strong plus.","description_format":"text","description_chars":4879,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Security Compliance","Medical AI"],"lifecycle":[{"event":"open","at":"2026-10-02T09:50:59Z"}],"visa":[{"country":"CA","licensed_sponsor":true,"evidence":"Approved LMIA in the last two years","filings_12m":0,"filings_prev_12m":1,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:10:52+00:00","sources":["ESDC: employers issued a positive LMIA"],"filings_for_role_12m":0}],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.204,"p_room":0.28,"age_days":210,"expected_fill_days":27,"reasons":["conf:18","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/signal-1-security-engineer","json_url":"https://alion.io/job/signal-1-security-engineer.json","meta":{"generated_at":"2026-10-24T00:08:15Z","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":187,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":175999},"rest":"https://alion.io/mcp/rest/get_company?id=175999"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsignal-1-security-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%2Fsignal-1-security-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%2Fsignal-1-security-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/signal-1-security-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsignal-1-security-engineer"}]}
