You will lead the team responsible for the critical infrastructure that handles User Management, SSO, EntraID, and our Public API. Your mission is to ensure that while the product scales, our \"base\" remains rock-solid, providing high throughput and millisecond-latency for our most critical services. If you thrive on solving complex distributed systems problems and take pride in enabling other engineers to move faster, this role is for you.\nCandidates must be located within driving distance from our Baltimore HQ.\nA Day in the Life:\nArchitect Core Services: Design and evolve the platform’s \"Identity-as-a-Service\" layer, ensuring high availability and consistency across user onboarding, SSO, and API key management.\nOptimize High-Scale Systems: Build and maintain data retrieval systems capable of accessing millions of records in milliseconds.\nDrive Reliability & SLAs: Implement rigorous monitoring, alerting, and performance tuning to meet and exceed strict reliability and low-latency targets.\nLead API Strategy: Own the development and lifecycle of our Public API, ensuring it is intuitive for customers and robust under heavy load.\nSet the Engineering Standard: Serve as a technical mentor and example for the broader engineering organization, championing best practices in asynchronous communication and system design.\nInnovate through Infrastructure: Strategically utilize caching layers and database optimizations to solve for high-concurrency challenges\nRequired Skills & Abilities:\nNode.js & PHP Ecosystems: Expert-level proficiency in Node.js for building high-concurrency services, paired with professional experience in PHP to manage and migrate legacy logic.\nHigh-Performance Database Architecture: Mastery of Relational Databases (PostgreSQL/MySQL), specifically in designing schemas that maintain strict ACID compliance.Proven ability to execute zero-downtime migrations and complex query optimizations that reduce CPU/IO overhead.\nSub-Millisecond Caching Strategy: Deep experience with Redis or Memcached to build \"speed layers\" for notification systems and session management. Sophisticated understanding ofcache invalidation patterns to ensure data consistency across a distributed environment.\nDistributed Systems & Scalability: Practical experience implementing Read/Write splitting, horizontal sharding, and multi-region failover to ensure \"five nines\" (99.999%) availability. Architectural fluency in the CAP Theorem, with the ability to make informed trade-offs between strong and eventual consistency based on the specific needs of Identity vs. Reporting.\nAsynchronous Data & Eventual Consistency: Expertise in Event-Driven Architecture using message brokers like Kafka or RabbitMQ to handle high-volume data flows. Experience implementing Change Data Capture (CDC) or similar patterns to synchronize platform usage data with external CRM systems like Salesforce without impacting core service performance.\nIdentity & Security Protocols: Comprehensive knowledge of SSO (EntraID/Azure AD), OAuth2, and OpenID Connect, with a focus on secure, high-throughput API Key management.\nObservability-Driven Development: A \"monitor-first\" mindset, using tools to track database contention, connection pooling, and latency bottlenecks before they impact the end user.\n Experience using AI tools: we are an AI first company and you should be comfortable using AI to code, debug and gather information from multiple sources.\nDesired Skills:\nExperience transitioning legacy PHP services into modern Node.js microservices.\nFamiliarity with event-driven architectures and message brokers (e.g., Kafka, RabbitMQ).\nPrior experience in a \"Platform\" or \"Foundations\" team where your primary customers were other internal developers.\nEducation & Experience:\nBachelor’s Degree in Computer Science, Computer Engineering, Software Engineering or related field. Equivalent experience may substitute for education.\n6+ years of related experience\nAlertus Career Advantages:\nUnlimited Paid Time Off\nPaid Holidays\n401(k) Retirement Plan \nMedical, Dental, and Vision Plans\nShort-term Disability, Accident, Hospital, and Cancer Insurance\nLive Near Your Work HomeBuying Incentive\nEmployee Referral Bonuses\nFlex Scheduling","description_format":"text","description_chars":4535,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Retirement plans"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Civil Defense","Access Control & Alarm Systems"],"lifecycle":[{"event":"open","at":"2026-11-13T21:26:09Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":73,"reasons":["conf:0","win:early"],"computed_at":"2026-11-13T22:21:47Z"},"pay":{"stated_usd_annual":170000,"is_top_pay":false},"html_url":"https://alion.io/job/alertus-technologies-lead-backend-engineer","json_url":"https://alion.io/job/alertus-technologies-lead-backend-engineer.json","meta":{"generated_at":"2026-11-13T22:21:47Z","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":44619,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":669052},"rest":"https://alion.io/mcp/rest/get_company?id=669052"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Falertus-technologies-lead-backend-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Falertus-technologies-lead-backend-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Falertus-technologies-lead-backend-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/alertus-technologies-lead-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falertus-technologies-lead-backend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4284627}},{"tool":"search_jobs","arguments":{"company":"alertus.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4284627},"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.
