In addition to some of the world’s largest enterprises and government agencies, more than 30% of the world’s top MSSPs rely on our platform. We’re at the forefront of protecting organizations against sophisticated cyber threats using cutting-edge AI and automation technologies. Our culture is built on diversity, openness, and collaboration, fostering creativity and innovation that drives real impact in the market.\n\nPosition Overview\nWe are looking for a Senior or Staff Software Engineer to take ownership of one or more integration domains on our Automation-Driven Open & Unified SecOps Platform (powering our AI-driven SIEM, NDR, Open XDR, and Multi-Layer AI).\nThis role requires delivering robust, production-grade integrations that support our growing customer base, while driving the architecture forward so the platform can scale to the next level. You will deliver microservice-based solutions spanning both traditional and AI-native integration patterns-REST, GraphQL, streaming APIs, MCP, and LLM-powered automation-connecting our platform with a wide range of cybersecurity tools and third-party services. You will also design, develop, and maintain the parsing and normalization components that turn raw security data from hundreds of sources into the unified schema our detection and analytics engines rely on.\nPlease note, as part of our interview process, we will be inviting successful finalists for an on-site interview to meet with our team. \nWhat You Will Own\nWe need someone who focuses on the work AI cannot do-and uses AI to amplify everything else.\nThe work only you can do\nOwn one or more integration domains end-to-end: roadmap, architecture decisions, trade-offs, and delivery. You identify what needs solving, scope it, and drive it to completion.\nOwn and evolve shared integration frameworks, such as the parser framework: identify patterns worth abstracting, design the primitives other engineers build on, improve performance on hot paths, and raise the reliability and testability bar across the team’s output.\nMake the design calls that require judgment-schema mapping, normalization trade-offs, how to handle ambiguous or malformed data, when to generalize versus when to special-case, when to evolve the framework versus work around it.\nPartner with detection and data teams to make sure ingested data serves downstream use cases, not just passes validation.\nMentor junior engineers through design discussions and code reviews, helping them grow into independent owners.\nWhat you’ll use AI to amplify\nAccelerate your own design and development workflow using LLM-based coding assistants, AI-driven testing, and automated code review.\nUse LLMs to analyze unfamiliar log samples, propose initial parsing rules, and bootstrap new integrations faster-while applying human judgment to catch what AI gets wrong.\nAutomate repetitive engineering tasks-builds, deployments, monitoring, incident triage, parser regression testing, schema diffing-using AI and scripting, so the team spends more time on high-value work.\nChampion AI adoption across the team: help colleagues integrate AI tools into their daily work, build internal tooling where it adds leverage, and measure the efficiency gains.\nRequirements\nBachelor’s or Master’s degree in Computer Science, Engineering, or a related field\n5+ years of backend software development experience, including integration, data parsing, or log processing work, with 1+ years as a technical lead or proven experience in taking full ownership of a project.\nStrong proficiency in at least one general-purpose programming language (e.g., Python, Go, Java, or C++), with a track record of writing production-quality code in it.\nExperience with API design and integration (REST, GraphQL, streaming), including secure API patterns (OAuth, API keys, rate limiting).\nSolid understanding of common log and data formats (JSON, XML, CSV, syslog, key-value, unstructured text), regular expressions, and data normalization and schema design.\nDemonstrated ability to use AI tools (e.g., Copilot, Cursor, Claude, ChatGPT) to meaningfully accelerate engineering workflows-not just experimentation, but regular use in production work. You have the judgment to know when AI output is trustworthy and when it needs human expertise.\nStrong problem-solving skills and clear communication with both engineers and non-technical stakeholders.\nPreferred Qualifications\nExperience in cybersecurity domains (SOAR, EDR, SIEM, XDR, firewalls, IDS/IPS, cloud security services) and the kinds of data security tools emit.\nExperience building and operating microservices in production.\nHands-on experience with large-scale data processing, real-time pipelines, or event-driven architectures (e.g., Kafka, Spark).\nStrong background in distributed systems, message queues (Kafka, RabbitMQ), or orchestration frameworks (Celery, Airflow, or similar).\nFamiliarity with cloud platforms (AWS, Azure, GCP) and their logging services (CloudWatch, Azure Monitor, Cloud Logging), and containerized deployments (Docker, Kubernetes, Helm).\nExperience with AI service integration (LLM APIs, embedding services) or AI-native integration patterns-such as MCP (Model Context Protocol), function calling, or agent orchestration frameworks-or hands-on experience building systems that incorporate LLMs or AI services into workflows or product features.\nHands-on experience using LLMs for log analysis, parser generation, or schema inference-or building internal tooling that applies AI to data engineering workflows.\nWhy Join Us\nWork at the forefront of cybersecurity innovation within a dynamic, fast-growing team.\nOpportunity to significantly influence and shape the integration architecture of a next-generation SecOps platform powered by AI and automation.\nCompetitive salary and ample career growth opportunities.\nBenefits\nPre-IPO Stock Options (equity opportunity)\nMedical, Dental & Vision care\nLife Insurance\n401(k)\nEmployee Assistance Program\nEmployee Discount Program\nPaid time off\nReferral Program\nRewards and Recognition Program\nThe salary for this role will be between USD $160,000 to $245,000 per year. The salary at offer will be determined by a number of factors such as candidate’s location, experience, knowledge, skills and abilities.","description_format":"text","description_chars":6379,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Growth opportunities","Life insurance","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Network Security","Information Security","Security Operations"],"lifecycle":[{"event":"open","at":"2026-10-27T23:17:52Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 7 · green card filings: 3","filings_12m":7,"filings_prev_12m":7,"green_card_filings_12m":3,"median_offered_wage_usd":147500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+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":5}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":41,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-10-29T05:49:05Z"},"pay":{"stated_usd_annual":245000,"is_top_pay":false},"html_url":"https://alion.io/job/stellar-cyber-senior-staff-software-engineer-integration-team","json_url":"https://alion.io/job/stellar-cyber-senior-staff-software-engineer-integration-team.json","meta":{"generated_at":"2026-10-29T15:28:04Z","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":23207,"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":2596},"rest":"https://alion.io/mcp/rest/get_company?id=2596"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fstellar-cyber-senior-staff-software-engineer-integration-team"},{"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%2Fstellar-cyber-senior-staff-software-engineer-integration-team"},{"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%2Fstellar-cyber-senior-staff-software-engineer-integration-team"},{"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/stellar-cyber-senior-staff-software-engineer-integration-team\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fstellar-cyber-senior-staff-software-engineer-integration-team"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3366311}},{"tool":"search_jobs","arguments":{"company":"stellarcyber.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3366311},"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.
