    🚀AIMPROSOFT — Principal AI Platform Engineer Opportunity!

     

    Aimprosoft is looking for a senior-level AI engineer who will design and lead the architecture of an enterprise-grade AI platform, evolving from an internal RAG-based assistant into a scalable, market-ready knowledge and automation product.

     

    🎯About the role:

    This is a principal-level role with high autonomy and architectural ownership. You will define the technical direction, key design principles, and long-term platform strategy for AI-powered knowledge discovery, semantic search, and business automation across multiple domains

    🔑Core Responsibilities:

    • Define the end-to-end architecture of an AI knowledge and automation platform
    • Make independent decisions and lead the technical direction
    • Design scalable retrieval systems beyond naive RAG implementations (semantic, document-level, process-level)
    • Establish reasoning and orchestration patterns for multi-step business use cases
    • Balance product vision, technical feasibility, and long-term maintainability
       

    🔥What We Need From You:

    • Proven experience designing production AI or search platforms from scratch
    • Experience moving from single-use assistant to multi-domain, multi-use platforms
    • API-first and platform-oriented system design
    • Strong understanding of trade-offs in scale, latency, relevance, and cost
    • Ability to design systems that remain explainable, debuggable, and governed
    • Deep expertise in RAG, semantic search, and knowledge retrieval systems
    • Vector databases, hybrid search, semantic indexing, and relevance ranking
    • Architecture for document-, entity-, and process-level knowledge modeling
    • Advanced LLM integration and reasoning design (structured, controlled, role-based)
    • Proven experience with agent orchestration as a controlled architectural pattern including memory, tools, learning, task decomposition, etc
    • Orchestration of AI workflows for automation use cases
    • Experience with AI observability tools
       

    📌 This Role Is Designed For Engineers Who:

    • Enjoy thinking in platforms and long-term systems, not one-off features
    • Are comfortable defining direction in ambiguous problem spaces where assumptions must be made explicit
    • Care deeply about architectural clarity, system boundaries, and ownership
    • Naturally reason about failure modes, trade-offs, and system limits
    • Balance ambitious technical vision with practical constraints
    • See governance, observability, and predictability as core parts of good engineering — not afterthoughts
       

    💼What We Offer:

    • A competitive salary that appreciates your skills and experience
    • Cozy atmosphere and modern approaches. We have neither bureaucracy nor strict management nor “working under pressure” conditions
    • Opportunity to implement your ideas, tools, and approaches. We are open to changes and suggestions aimed at improvement

    The product is redefining post-acute care by replacing fragmented, manual workflows with intelligent AI-driven automation. We help healthcare providers manage patients, not paperwork, by delivering robust throughput and intelligence across clinical, financial, and compliance operations. 


    The Role: 

    We are looking for a product-focused Full-Stack Engineer to join our team. You will be a key player in building our system, which involves developing sophisticated APIs that interface with Electronic Medical Records (EMR) and building advanced web-scraping tools for healthcare referral platforms.

     

    This isn't just a coding role; we are looking for an engineer who understands the "Why" behind the "What." You will work in a high-efficiency environment where AI tools (Cursor, Gemini, Claude Code) are part of the daily workflow to maximize output and quality.

     

    Technical Stack

    • Frontend: React (Proficient)
    • Backend: Go (Primary/Preferred) or Node.js
    • Languages: TypeScript (Strongly Preferred)
    • Workflows & Scraping: Playwright, Temporal (Airflow experience is a plus)
    • Data: EMR website scraping, PDF parsing, and data point extraction
    • Architecture: System Design focus; Cloud-native development

     

    What You’ll Do

    • Automate Workflows: Design systems that remove data access bottlenecks and automate clinical data entry.
    • Build the "Injection Track": Develop and maintain APIs that reliably scrape and sync data from EMRs and referral platforms in real-time.
    • Collaborate via Design: Participate in "1s design discussions" to align on architecture before implementation.
    • Leverage AI: Use modern AI-assisted development tools (Cursor, Claude Code, LLM wrappers) to build faster and smarter.
    • Take Ownership: Move beyond task execution to ownership—meaning you don't just follow instructions; you understand the business context and ensure the solution fits the need.

     

    What We’re Looking For

    • 4+ Years Experience: You have a solid foundation in full-stack development and have worked on product-level code.
    • Communication & Alignment: You understand that "going away and building the wrong thing" is a failure. You prioritize constant "connect" and alignment with the team.
    • Problem Solvers: You are comfortable with the "messy" side of data—parsing PDFs, scraping complex websites, and ensuring data reliability.
    • AI-Forward: You are already using (or eager to master) AI coding tools to 2x your productivity.

     

    Our Culture & Philosophy

    • Context is King: We provide clear business requirements and motivation. We expect you to understand the "Why" to build better "Whats."
    • Execution Levels: We expect our engineers to operate at an "I do" level—taking a problem and owning the solution from design to deployment.
    • Efficient Growth: We value unique perspectives and a proactive approach to work.

     

    We Offer:

    • Medical Insurance in Ukraine and Multisport program in Poland.
    • Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
    • Paid vacation, sick leaves, and official holidays.
    • Legal & Accounting services.
    • The company provides all necessary equipment.
    • English classes and Education reimbursement.

    About the role

    As a Software Development Engineer, you will contribute to all aspects of an agile software development life cycle, including design, architecture, development, documentation, testin,g and operations. You will push your design and architecture limits by owning all aspects of solutions end-to-end, through software development. Apart from that, you will be responsible for industrialization of existing prototypes, containerization, and organization of CD/CI workflows and automated tests. Context of the role: Vessels operate in the middle of the ocean, with very limited connectivity that is both costly and slow. We install the device on the vessel, and all processing runs directly on the device rather than in the cloud. Only updates and troubleshooting are performed via the available connection. You must be familiar with highly optimized coding practices and extensive development of automated tests in pre-production.
     

    Requirements 
    Candidates for this position are expected to have technical background in Computer Science and Engineering, including object-oriented design, data structures, and algorithms

    • Experience in software development (Python, C/C++ is a plus) for performance-critical applications in resource constrained environment (example: IoT edge devices) 
      • Knowledge of software development lifecycle (CD/CI, Git, Docker, ...) for deploying and maintaining applications on remote devices 
      • A taste for high-quality software (clean code, high test coverage, peer reviews) 
      • Excellent written and oral communication in English (international team and clients) 
      • Experience in IoT edge device deployment is preferable 
      • MCU/sensor programming and industrial communication protocols knowledge is a plus 
      • Knowledge of signal and time series processing algorithms is a plus.
