Senior AI-Native Software Developer (Remote)

Cyrantos is partnering with a healthcare and financial intelligence platform to find a highly experienced Senior AI-Native Software Developer to join their team. This is a remote position with a start date as soon as the candidate successfully completes the interview process.

Monthly B2B salary: 28,000 - 35,000 PLN net.

About the Role: As a Senior AI-Native Software Developer, you will help design and build production-grade agentic workflow platforms for healthcare data analytics and financial portfolio intelligence. You will work at the intersection of software engineering, AI agents, data platforms, deterministic analytical engines, and cloud-native architecture. The focus is on building reliable systems in which LLM-powered agents collaborate with business rules, statistical models, APIs, and human approval workflows. Our client is looking for a senior engineer who treats AI as part of a broader software system and not as a standalone chatbot as well as can turn experimental agent concepts into secure, testable, explainable, and production-ready platforms.

Key Responsibilities: Design and implement multi-agent workflows using frameworks such as LangGraph, Strands Agents, or OpenAI Agents SDK

• Integrate agent workflows with AWS Step Functions, Event
• Bridge, SQS, Lambda, and container-based services
• Build secure tools and APIs used by AI agents to access data, calculations, optimization engines, and compliance rules
• Integrate LLMs through Amazon Bedrock, OpenAI, Anthropic, or similar platforms, implementing structured outputs, model routing, fallbacks, prompt versioning, and cost controls
• Develop RAG pipelines using approved internal, regulatory, clinical, or financial knowledge sources
• Connect AI components with deterministic Python services, statistical models, rules engines, and optimization algorithms, implementing human-in-the-loop review, audit trails, observability, and model evaluation
• Contribute to architecture decisions, code reviews, testing, deployment, and engineering standards
• Candidate Profile:

Strong commercial experience with Python and modern backend development

• Experience building cloud-native systems, preferably on AWS
• Practical experience integrating LLMs and developing agentic or AI-enabled applications
• Knowledge of APIs, event-driven architecture, asynchronous processing, and distributed systems
• Experience with relational databases, data pipelines, and structured data processing
• Strong understanding of software quality, security, testing, and production observability
• Ability to distinguish between tasks suitable for LLMs and those requiring deterministic implementation
• Experience with LangGraph, Strands Agents, Temporal, or AWS Step Functions is a plusHands-on experience with Amazon Bedrock, OpenAI, or Anthropic APIs is beneficial
• Knowledge of RAG, vector databases, embeddings, and reranking is a plus
• Familiarity with ML pipelines (MLflow, SageMaker), compliance, data lineage, model governance, or human-approval workflows is beneficial
• Nice to have:

Exposure to healthcare and financial industries
