We deliver industry-leading silicon design, IP, simulation and analysis solutions, and design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow. You Are\nYou have spent years building software that solves hard security problems, and now you see Artificial Intelligence transforming how cybersecurity teams operate. You understand that AI is more than chatbots and proof-of-concepts. It is a powerful capability that can analyze vast amounts of security data, automate investigations, accelerate decision making, and fundamentally change how organizations defend against emerging threats.\nYou are the kind of engineer who can take a cybersecurity challenge, conceptualize an AI-powered solution, design the architecture, build the application, and own it all the way through production deployment. You enjoy turning ideas into real products that security teams use every day. Combining large language models, retrieval-augmented generation, machine learning, and automation to solve practical security problems that create measurable business value is what drives you.\nWaiting for someone else to define the roadmap is not your style. You work directly with security architects, analysts, engineers, and leadership to understand the problem, identify opportunities, and develop solutions that improve efficiency, visibility, and risk management. You are equally comfortable discussing agent architectures, writing Python code, designing APIs, evaluating models, and presenting your solution to executive stakeholders.\nAt Synopsys, you will help build the next generation of AI-powered cybersecurity platforms that automate security processes, enhance decision making, improve risk visibility, and establish a strong foundation for defending against AI-enabled threats.\nWhat You'll Be Doing\nLead end-to-end design, development, and delivery of AI-powered cybersecurity solutions, from problem definition through deployment and operational support\nDesign and develop GenAI applications, AI agents, RAG platforms, and advanced analytics solutions that automate cybersecurity processes and improve operational efficiency\nBuild secure LLM-powered services and agentic workflows that integrate with security technologies including source-code repositories, SAST/DAST tools, threat models, cloud platforms, SIEM, SOAR, IAM, CMDB, and vulnerability management systems\nWork directly with security architects, analysts, and engineering teams to identify high-impact use cases, translate requirements into technical designs, and deliver production-ready solutions\nEvaluate, test, and implement large language models and machine learning frameworks to solve real security challenges like automated threat analysis, policy enforcement, and risk assessment\nOwn the full application lifecycle including architecture decisions, code quality, testing, deployment pipelines, monitoring, and continuous improvement\nPresent technical solutions and business outcomes to security leadership and executive stakeholders, demonstrating measurable impact on operational efficiency and risk reduction\nThe Impact You Will Have\nAccelerate security incident response times by automating investigation workflows that currently require hours of manual analysis\nEnable security teams to scale their operations without proportional headcount growth through intelligent automation and decision support\nReduce mean time to remediation for vulnerabilities by building AI systems that prioritize, contextualize, and recommend fixes based on actual business risk\nEstablish Synopsys as a leader in AI-powered security operations, creating platforms that other organizations will look to as the standard\nFree security analysts from repetitive tasks so they can focus on strategic threat hunting and architectural improvements\nImprove visibility into security posture across the organization by building AI systems that synthesize data from disparate tools into actionable intelligence\nCreate a defensible foundation against AI-enabled threats by building AI-native security capabilities before adversaries fully weaponize the technology\nWhat You'll Need\n5+ years of hands-on software development experience building production applications, with at least 2 years focused on AI/ML or security domains\nStrong proficiency in Python for building AI applications, APIs, automation, and integration with security tools\nDemonstrated experience designing and deploying GenAI applications, RAG systems, or AI agents in production environments\nWorking knowledge of large language models, prompt engineering, vector databases, and retrieval-augmented generation architectures\nSolid understanding of cybersecurity principles, tools, and workflows including SIEM, SOAR, vulnerability management, IAM, or cloud security platforms\nExperience integrating with security technologies such as SAST/DAST tools, threat modeling platforms, CMDB systems, or security orchestration tools is a plus\nBachelor's or Master's in Computer Science, Cybersecurity, Engineering, or equivalent practical experience\nWho You Are\nYou can walk into a room with security analysts who are drowning in alerts and walk out with a clear plan for an AI agent that triages the noise and surfaces what actually matters\nYou make architectural decisions that balance cutting-edge AI capabilities with the reality of what security teams can actually deploy, maintain, and trust\nYou push back when a use case is too vague or when leadership wants AI for the sake of AI, and you redirect the conversation toward measurable security outcomes\nYou write code that other engineers can read, maintain, and extend, because you know your solution will outlive your direct involvement with it\nYou stay current with AI and security research not by chasing hype but by evaluating what actually solves problems your teams face today\nYou can explain complex AI concepts like RAG, embeddings, or agent frameworks to a non-technical security leader in two minutes without losing the technical accuracy \nThe Team You'll Be Part Of\nYou will join a newly formed AI Security team of four people, currently based in the US, including an AI Architect, AI Engineers, and AI Security Managers. You will report to a Cyber Security Senior Architect. This role is part of the team's expansion into Greece, and you will work closely with an additional AI Automation Engineer who will join the Athens team. The team operates in a distributed environment across Athens and the US, and you will work hybrid from the Athens office. The team is in build mode, defining AI security architecture, selecting tools, and establishing the security foundation for AI across the enterprise and in products\nRewards and Benefits\nWe offer a comprehensive range of health, wellness, and financial benefits to cater to your needs. Our total rewards include both monetary and non-monetary offerings. Your recruiter will provide more details about the salary range and benefits during the hiring process.\n\nAt Synopsys, we want talented people of every background to feel valued and supported to do their best work. Synopsys considers all applicants for employment without regard to race, color, religion, national origin, gender, sexual orientation, age, military veteran status, or disability.","description_format":"text","description_chars":7575,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["EDA Software","Information Security","Application Security","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-09-07T22:53:51Z"},{"event":"close","at":"2026-09-14T10:55:12Z"},{"event":"restore","at":"2026-09-14T19:42:59Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 178 · green card filings: 177","filings_12m":178,"filings_prev_12m":208,"green_card_filings_12m":177,"median_offered_wage_usd":157472,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":52},{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-30T06:20:16+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.654,"p_room":0.28,"age_days":52,"expected_fill_days":15,"reasons":["conf:2","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/synopsys-senior-ai-security-developer-sr-staff-engineer-18273","json_url":"https://alion.io/job/synopsys-senior-ai-security-developer-sr-staff-engineer-18273.json","meta":{"generated_at":"2026-10-30T21:14:31Z","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":11557,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":39954},"rest":"https://alion.io/mcp/rest/get_company?id=39954"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsynopsys-senior-ai-security-developer-sr-staff-engineer-18273"},{"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%2Fsynopsys-senior-ai-security-developer-sr-staff-engineer-18273"},{"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%2Fsynopsys-senior-ai-security-developer-sr-staff-engineer-18273"},{"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/synopsys-senior-ai-security-developer-sr-staff-engineer-18273\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsynopsys-senior-ai-security-developer-sr-staff-engineer-18273"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":519319}},{"tool":"search_jobs","arguments":{"company":"synopsys.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":519319},"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);
