Our technology sits at the crossroads of two seismic shifts in modern computing: agentic AI and high-performance cloud data infrastructure. Think of it as the intelligence layer that turns massive streams of user behavior into real-time insight and action.\nOur customers range from top consumer brands to cutting-edge fintech and SaaS companies; all using our technology to deliver faster, smarter, more personalized experiences. We believe in speed without drama, autonomy without ego, and impact without bureaucracy.\nThe Role\nWe’re searching for a Principal Engineer to shape and scale our real-time data streaming systems - the backbone powering billions of in-the-moment decisions across our platform. You’ll architect and improve services that process millions of events per second with single-digit millisecond latency, touching almost every part of our data plane.\nThis is a hands-on technical leadership role on a small team tackling challenges few companies face: ultra-low-latency ingestion, distributed caching, deduplication at scale, and fault-tolerant event computation. You’ll be the type of engineer who gets excited by raw throughput charts, but even more excited when they translate into better customer outcomes.\na\nRequirements\nWhat We Value\nDeep expertise in distributed systems, stream processing, or event-driven architectures (Kafka, Flink, Pulsar, etc.).\n\nExperience building low-latency or high-throughput systems at scale.\n\nA product mindset. You care deeply about the end impact of your code.\n\nComfort owning major initiatives in a fast-moving, high-autonomy environment.\n\nStrong communication skills and a desire to mentor others.","description_format":"text","description_chars":1808,"description_truncated":false,"requirements":{"experience_years_min":null,"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":["Executive Search"],"lifecycle":[{"event":"open","at":"2026-10-20T11:23:43Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.158,"p_room":0.28,"age_days":262,"expected_fill_days":28,"reasons":["conf:2","stale_co","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/calliere-principal-engineer-real-time-data-systems","json_url":"https://alion.io/job/calliere-principal-engineer-real-time-data-systems.json","meta":{"generated_at":"2026-10-31T11:07:18Z","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":17089,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":4423613},"rest":"https://alion.io/mcp/rest/get_company?id=4423613"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcalliere-principal-engineer-real-time-data-systems"},{"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%2Fcalliere-principal-engineer-real-time-data-systems"},{"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%2Fcalliere-principal-engineer-real-time-data-systems"},{"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/calliere-principal-engineer-real-time-data-systems\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcalliere-principal-engineer-real-time-data-systems"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":2918951}},{"tool":"search_jobs","arguments":{"company":"callieregroup.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":2918951},"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.
