The platform combines cloud-native architectures, large-scale data processing, healthcare interoperability, API platforms, and AI-enabled capabilities.\nThis is a highly technical, hands-on role within the Platform Architecture team. You will work across multiple engineering teams, solving complex platform-level challenges related to scalability, reliability, interoperability, data consistency, API governance, and production architecture.\nIf you enjoy designing systems and validating architectural decisions through code, this role offers the opportunity to make a significant impact on a large-scale healthcare platform.\nYour Responsibilities\nDesign and build large-scale distributed systems and event-driven architectures.\n\nDefine and evolve Kafka-based platform architecture, including topic design, schema governance, reliability patterns, and failure recovery strategies.\n\nDesign and govern REST and federated GraphQL APIs.\n\nBuild reusable platform capabilities that accelerate product development across engineering teams.\n\nContribute directly to production code, prototypes, proofs of concept, and reference implementations.\n\nCollaborate with AI engineering teams to integrate LLM and agent-based solutions into production systems.\n\nShape healthcare data architecture, interoperability standards, and large-scale data processing solutions.\n\nDrive architectural reviews, technical decision-making, and engineering standards.\n\nDesign secure, scalable, and resilient cloud-native solutions.\n\nMentor senior engineers and technical leaders across multiple teams.\n\nRequirements\nMust Have\n8+ years of software engineering experience.\n\nStrong hands-on backend development experience with Python.\n\nDeep understanding of distributed systems and large-scale platform architectures.\n\nExperience designing and implementing event-driven architectures using Kafka or similar technologies.\n\nStrong expertise in REST API and GraphQL architecture.\n\nExperience designing, building, and operating production-grade systems.\n\nStrong AWS and cloud-native architecture experience.\n\nExperience with Kubernetes and containerized environments.\n\nStrong understanding of data architecture, data modeling, and high-volume systems.\n\nHands-on experience with technologies such as MongoDB, ClickHouse, Databricks, Spark, or similar.\n\nKnowledge of authentication, authorization, OAuth, OIDC, multi-tenancy, and security best practices.\n\nExcellent communication skills and ability to influence technical decisions across multiple teams.\n\nStrong hands-on engineering mindset.\n\nProfessional English communication skills.\n\nNice to Have\nExperience with healthcare platforms, FHIR, HL7, EHR integrations, or healthcare interoperability.\n\nExperience working with sensitive and regulated data (PHI/PII).\n\nKnowledge of healthcare compliance and security standards.\n\nExperience with Java/Spring Boot and/or TypeScript/Node.js.\n\nExperience with federated GraphQL platforms.\n\nExperience integrating LLMs or AI agents into production environments.\n\nFamiliarity with AI-assisted development tools such as GitHub Copilot, Cursor, Claude Code, or similar.\n\nExperience establishing engineering standards and platform patterns used across multiple teams.\n\nPrevious Staff or Principal-level engineering experience.\n\nWhat We Offer\nOpportunity to shape the core architecture of a modern healthcare technology platform.\n\nWork on challenging distributed systems and cloud-native engineering problems at scale.\n\nInfluence architecture and engineering standards across multiple teams.\n\nCollaborate with product, security, data, AI, and engineering stakeholders.\n\nCombine architectural leadership with hands-on software development.\n\nWork with modern technologies spanning data platforms, cloud infrastructure, APIs, and AI solutions.\n\nFlexible and collaborative international environment.\n\nWhy Join Us?\nThis role is ideal for an experienced engineer who wants to operate at the intersection of architecture and implementation. You will help define the technical foundations of a next-generation healthcare platform while remaining close to production systems, engineering challenges, and real business impact.\nTech stack\nPython","description_format":"text","description_chars":4572,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-08T23:50:21Z"}],"visa":[],"liveness":{"score":99,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.993,"p_room":1,"age_days":11,"expected_fill_days":47,"reasons":["seen:11","urgency","velocity","win:early"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/intellias-principal-python-engineer","json_url":"https://alion.io/job/intellias-principal-python-engineer.json","meta":{"generated_at":"2026-10-17T11:28:40Z","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":14986,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":13249},"rest":"https://alion.io/mcp/rest/get_company?id=13249"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fintellias-principal-python-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%2Fintellias-principal-python-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%2Fintellias-principal-python-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/intellias-principal-python-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fintellias-principal-python-engineer"}]}
