Our consolidated platform and services address the needs of enterprises by improving security and reducing TCO, while simultaneously building trust between AppSec, developers, and CISOs. At Checkmarx, we believe it's not just about finding risk, but remediating it across the entire application footprint and software supply chain with one seamless process for all relevant stakeholders. We are honored to serve more than 1,800 customers, including 40 percent of all Fortune 100 companies, such as Siemens, Airbus, Salesforce, Stellantis, Adidas, Walmart, and Sanofi.\nAbout the role\nWe're looking for a Senior AI Engineer to join one of our R&D teams building the AI-driven core of our product. Beyond building, we want someone who tracks the AI landscape closely: new models, frameworks, and agent architectures as they emerge; and who can turn that knowledge into real recommendations: evaluating whether a new tool, model, or technique is worth adopting, and helping the team decide what to build vs. buy vs. integrate.\nThe specific product area may evolve with our roadmap, but the core of the job stays constant: AI-driven features, applied judgment about the AI tooling landscape, and cloud-native architecture in Go.\nWhat you'll do\n Design, build, and own LLM-powered pipelines and agent-based systems that find, triage, and remediate security risk in production, at scale\nDesign retrieval and context strategies (RAG, tool use, memory) that ground model behavior in our product's data and domain\nDefine and run evaluations for model/agent quality and use them to drive iteration and model selection\nEvaluate emerging AI tools, models, and frameworks against our product needs, producing clear build-vs-buy-vs-integrate recommendations for the team and leadership\nStay ahead of the AI landscape: new LLM releases, agent architectures, orchestration frameworks, and techniques and translate relevant developments into concrete engineering proposals\nOwn the reliability of AI features in production: guardrails, structured output validation, fallback behavior, and observability tuned for LLM-based systems\nParticipate in design discussions and code reviews, bringing an AI-informed perspective to architecture decisions\nRequirements\nWhat you'll need\n5+ years of professional software engineering experience, with strong hands-on experience building with LLMs and AI agents, not just experimenting with them\nExperience designing RAG pipelines, retrieval strategies, or context/memory systems for LLM applications\nPractical experience evaluating model and agent quality (accuracy, hallucination, latency, cost) and using evals to guide decisions\nA demonstrated habit of evaluating and comparing AI tools, models, or vendors, with informed opinions on tradeoffs\nExperience with cloud AI services (AWS Bedrock, Azure OpenAI, Vertex AI)\nStrong proficiency in Go and/or Python\nSolid understanding of distributed systems (message queues, gRPC/REST APIs, relational databases) and experience with Docker/Kubernetes\nStrong testing, CI/CD, and observability fundamentals\nExcellent English communication skills\nNice to have\nA genuine research habit, following AI research/practitioner communities\nExperience with vector databases and embedding models\nApplication security knowledge\nGitOps tooling (ArgoCD, Helm), OpenTelemetry\nWhat we have to offer\nCheckmarx offers a great work environment, professional development, challenging careers, competitive compensation, great work-life balance, as well as great benefits and perks throughout the year.\nCheckmarx is an Equal Opportunity Employer. Employment decisions are made without regard to race, color, religion, national or ethnic origin, gender, sexual orientation, gender identity or expression, age, disability, or other characteristics protected by law.","description_format":"text","description_chars":3971,"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":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Cybersecurity","DevSecOps","Vulnerability Management"],"lifecycle":[{"event":"open","at":"2026-10-09T08:23:09Z"}],"visa":[],"liveness":{"score":31,"band":"fade","label":"Fading","p_open":1,"p_active":0.679,"p_room":0.45,"age_days":16,"expected_fill_days":10,"reasons":["conf:1","velocity","win:tail"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/checkmarx-senior-ai-engineer","json_url":"https://alion.io/job/checkmarx-senior-ai-engineer.json","meta":{"generated_at":"2026-10-22T07:42:02Z","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":3427,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":49151},"rest":"https://alion.io/mcp/rest/get_company?id=49151"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcheckmarx-senior-ai-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%2Fcheckmarx-senior-ai-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%2Fcheckmarx-senior-ai-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/checkmarx-senior-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcheckmarx-senior-ai-engineer"}]}
