Our platform connects to our customers codebases and engineering tools, and deploys AI agents that autonomously find, prioritize, and remediate security issues - from code-level vulnerabilities to architectural design gaps.\nAbout The Position\nWe are looking for a high-ambition engineer to join our team in Israel and own the\nintelligence layer of our platform: the agents that analyze customer codebases, reason about\nvulnerabilities, and produce remediations autonomously.\nFirst and foremost, this is a senior software engineering role. You will design and build production services, write code across the stack, and own what you ship end to end - the AI agents are software, and you build the systems they run on. This is not a prompt-tweaking role: you will design multi-step agentic systems end to end - context engineering, tool design, orchestration, evaluation, and production monitoring - on a \"zero legacy\" stack (Python, Temporal, K8s, and frontier LLMs). We value a low-ego mindset and a passion for solving deep technical challenges in a fast-paced, collaborative environment.\nResponsibilities\nBackend Development: Design and build high-performance production services using Python, FastAPI, and asynchronous workers - the foundation your agents run on.\n\nAgent Development: Design and build autonomous, multi-step AI agents for security analysis, code review, and threat modeling - including tool use, structured outputs, and long-running agentic loops.\n\nContext Engineering: Build the retrieval and grounding layer that feeds agents the right code, docs, and organizational knowledge at the right time.\n\nEvaluation & Quality: Own the eval pipeline - build benchmarks, measure agent output quality, catch regressions, and drive systematic prompt and model iteration.\n\nOrchestration: Run agents as durable Temporal workflows that survive failures, scale across tenants, and stay observable in production.\n\nLLM Operations: Manage prompt versioning, tracing, token economics, model selection, and fallback strategies across providers.\n\nEngineering Culture: Lead architectural discussions, participate in deep-dive code reviews, and drive incident response.\n\nRequirements\nAt least 4 years of experience in software development, designing, building, and operating production backend services.\n\nPython Expertise: Strong professional background with a focus on modern, asynchronous Python.\n\nAgentic AI Experience: Proven experience building LLM-powered agents in production - tool calling, multi-step reasoning, structured outputs - not just API wrappers or chatbots.\n\nEvaluation Mindset: You treat prompts and agents as systems to be measured, not vibes to be tuned. Experience with eval frameworks, tracing, or LLM observability.\n\nSystem Design: You can reason about latency, cost, reliability, and failure modes of LLM-based systems at scale.\n\nProblem Solver: A fast learner with outstanding problem-solving skills who thrives in a \"zero legacy\" environment.\n\nTeam Player: A collaborative engineer with a focus on collective success and technical excellence.\n\nNice-to-Have\nExperience with Temporal or similar distributed workflow engines.\n\nExperience with static analysis, program comprehension, or codebase-scale retrieval.\n\nBackground in cybersecurity or application security products.","description_format":"text","description_chars":3506,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-28T17:25:23Z"}],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.307,"p_room":0.28,"age_days":75,"expected_fill_days":30,"reasons":["conf:6","win:tail","crowd:"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/pi-senior-ai-engineer","json_url":"https://alion.io/job/pi-senior-ai-engineer.json","meta":{"generated_at":"2026-10-01T11:00:30Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2287,"day_limit":5000,"remaining_today":2713,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
