Principle Python Engineer (healthcare solution)

Intellias is looking for a Principle Python Engineer in  Platform Architect team to join a healthcare technology initiative focused on building a modern, scalable platform for connected health data and digital healthcare experiences.

This is a senior hands-on engineering role for someone who combines deep distributed-systems expertise, strong backend engineering skills, and architectural thinking . You will design and build platform capabilities used across multiple engineering teams, establish reusable architectural patterns, and help evolve a cloud-native healthcare platform operating at scale.

What project we have for you

The project is building a FHIR-based healthcare data platform that integrates data from EHRs, digital health applications, wearables, portals, and other healthcare data sources into a unified ecosystem.

The platform operates at the intersection of health data interoperability, distributed systems, API platforms, cloud infrastructure, and AI-enabled healthcare experiences . Its architecture includes event-driven processing, federated GraphQL and REST APIs, FHIR services, high-volume data storage and analytics, and integration points for LLM- and agent-based capabilities.

You will work horizontally across engineering teams rather than within a single product squad. The focus is on solving complex platform-level problems around scale, reliability, data consistency, interoperability, API governance, and production architecture .

This is not an architecture-only position. You will be expected to design, prototype, build, review, and operate production systems , staying close to both the code and real-world system behavior.

What you will do

• Design and build large-scale, event-driven distributed systems , including orchestrators, worker services, asynchronous processing pipelines, schema governance, and reliable consumer patterns.
• Define and implement platform architecture around Kafka , including topic and partition design, schema evolution, idempotency, consumer groups, retry strategies, and production failure handling.
• Own and evolve API architecture across REST and federated GraphQL , establishing scalable patterns for schema composition, versioning, contract evolution, and API governance.
• Design and build reusable platform capabilities that enable engineering teams to onboard new services and data sources with minimal custom implementation.
• Contribute directly to production code, prototypes, reference implementations, and technical proofs of concept.
• Partner with AI engineering teams to define reliable integration points for LLM- and agent-based capabilities , including retrieval, evaluation, guardrails, observability, latency, cost, and data-protection boundaries.
• Shape healthcare data architecture, including FHIR-based interoperability, terminology services, data-quality controls, high-volume storage, and analytical workloads .
• Drive architecture and technical design reviews, documenting key decisions, trade-offs, standards, and reusable engineering patterns.
• Use production telemetry, observability, and operational data to validate architectural decisions and troubleshoot complex distributed-system behavior.
• Establish architectural patterns for security, identity, multi-tenancy, scalability, resilience, and protected health data .
• Mentor senior engineers and technical leads in system design, distributed-systems engineering, and architectural decision-making.
• Collaborate closely with U.S.-based engineering, product, data, security, and AI stakeholders while working effectively across geographically distributed teams.
• Promote an AI-enabled engineering approach , using modern AI development tools where they improve engineering velocity, quality, analysis, documentation, testing, or architectural exploration.

What you need for this

• 8+ years of software engineering experience , with significant experience designing and operating large-scale distributed systems.
• Strong hands-on backend engineering skills in Python and/or another modern backend language, with the ability to work effectively across a polyglot environment and solid experience building production-grade services and APIs.
• Proven experience designing event-driven architectures , ideally using Apache Kafka or comparable distributed messaging technologies.
• Deep understanding of distributed-system fundamentals, including partitioning, idempotency, back-pressure, eventual consistency, failure recovery, and consistency/availability trade-offs.
• Strong experience designing and evolving REST APIs and GraphQL-based architectures , including schema design, versioning, composition, and contract governance.
• Strong system-design skills and demonstrated ownership of complex systems from architecture through implementation and production operation.
• Experience with cloud-native architectures on AWS , including Kubernetes-based environments, observability, scalability, resilience, and production operations.
• Strong data architecture fundamentals: data modeling, storage strategies, query optimization, and designing systems for high-volume transactional and analytical workloads.
• Practical experience with modern data and storage technologies such as MongoDB, ClickHouse, Databricks, Spark , or comparable platforms.
• Understanding of identity and security concepts such as OIDC, OAuth/token exchange, authorization, multi-tenancy, and data isolation .
• Ability to work effectively across a polyglot technology environment and make architectural decisions based on system requirements rather than technology preference.
• Strong communication and technical leadership skills, including the ability to drive architecture discussions, technical design reviews, and engineering standards across multiple teams.
• Strong hands-on engineering mindset — able and willing to build production code, prototypes, reference implementations, and tooling rather than operating exclusively at an architectural level.
• Professional English sufficient for direct collaboration with U.S.-based engineering and product stakeholders.

Nice to Have

• Experience with FHIR, HL7, EHR integrations, healthcare interoperability, or digital health platforms .
• Experience designing systems handling PHI/PII or other regulated and sensitive data .
• Familiarity with healthcare security and compliance requirements, including HIPAA-related architectural considerations.
• Experience with Java/Spring Boot, TypeScript/Node.js , or other languages used in large-scale backend ecosystems.
• Experience with federated GraphQL platforms such as WunderGraph Cosmo, Apollo Federation , or similar technologies.
• Practical experience integrating LLMs or AI agents into production systems , including retrieval, evaluation, guardrails, observability, latency, and cost considerations.
• Experience with AI-assisted software engineering tools such as Claude Code, GitHub Copilot, Cursor, or similar tools, and an ability to use them effectively throughout the engineering lifecycle.
• Experience establishing reusable platform patterns, architecture standards, or internal developer platforms used by multiple engineering teams.
• Previous Staff/Principal-level experience mentoring senior engineers and influencing architecture beyond a single team.
