Senior Backend Engineer (Python) needed to design and build the services that power a healthcare company enabling remote patient monitoring, clinical research, and personalized healthcare. You'll own Python services and REST APIs end to end — from discovery through to production — model and evolve the data behind them, and make foundational architectural decisions for a next-generation platform where scalability, security, and privacy are non-negotiable. You'll partner closely with frontend, mobile, clinical, and data teammates, set the technical bar for backend code and reliability, and mentor more junior engineers. This is a hands-on senior role for a backend engineer who leads non-trivial work independently and brings strong engineering judgement to a fast-paced, distributed environment.

What You'll Do:

• Drive foundational architectural decisions for our next-generation platform, ensuring scalability, security, and maintainability
• Design, build, and maintain Python services that expose well-documented, versioned REST APIs
• Model and evolve data with PostgreSQL (and NoSQL where appropriate), including schema migrations and query performance tuning
• Integrate with internal services and third-party systems (auth, payments, healthcare data sources) with clear contracts and graceful failure modes
• Design services with security and privacy by default, aligned with global healthcare compliance standards
• Write thorough automated tests at unit, integration, and contract levels using pytest
• Add the logging, metrics, and tracing needed to operate services confidently in production
• Participate in on-call and incident response for owned services, and drive blameless post-mortems and follow-ups
• Review code with care, pushing for clarity, simplicity, and good test coverage
• Use AI-assisted development tools effectively to accelerate delivery without compromising quality
• Document architecture decisions, runbooks, and API contracts so distributed teammates can pick work up easily
• Partner with product, design, and clinical stakeholders to scope features and trade-offs
• Mentor more junior backend engineers and help raise the bar on backend practices across teams

What We're Looking For:

• 3+ years of professional backend engineering experience shipping production services
• Bachelor's degree in Computer Science, Software Engineering, or a related technical field — or equivalent practical experience
• Strong, hands-on Python skills, including modern type hints, async patterns, and idiomatic project layout
• Production experience with at least one major Python web framework (FastAPI, Django, or Flask)
• A proven track record designing, building, and evolving REST APIs (OpenAPI / Swagger), with familiarity with API versioning, pagination, and error-handling conventions
• Solid SQL skills with PostgreSQL or MySQL — comfortable writing migrations and tuning queries
• Strong testing habits with pytest across unit, integration, and contract tests
• Confident with Git, code review, and trunk-based or short-lived-branch workflows
• Strong analytical and problem-solving skills, with attention to long-term maintainability
• An ownership mindset — you take features from idea to production and stay accountable after launch
• Clear written and verbal communication in English, with the ability to work asynchronously across time zones
• Pragmatism: you balance correctness, speed, and complexity appropriately for the stage of the product

Nice to Have:

• Experience working in regulated environments (HIPAA, GDPR, ISO 27001, SOC 2, or medical-device software)
• Working knowledge of event-driven architectures (Kafka, RabbitMQ, SQS, Pub/Sub)
• Experience with containerization and orchestration (Docker, Kubernetes)
• Familiarity with infrastructure as code (Terraform, Pulumi, CloudFormation)
• Exposure to observability tooling (OpenTelemetry, Datadog, Grafana, Sentry)
• Hands-on use of AI-assisted development tools to accelerate delivery
• Background in healthcare, life sciences, or another data-sensitive domain
• Experience with FHIR, HL7, or other healthcare interoperability standards
• Performance work on high-throughput or low-latency systems
• Hands-on experience deploying services to AWS, GCP, or Azure, and shipping changes through a CI/CD pipeline

Шукаємо Middle Software Engineer у продуктовий R&D-напрямок. Ми розробляємо та виготовляємо реальні апаратно-програмні комплекси й електронні рішення для застосування у складних польових умовах.

Команда швидко розширюється для створення високонавантажених систем, які виготовляються у великих серіях та забезпечують технологічну перевагу.
 

Чим належить займатися:

• Оптимізація та low-latency: оптимізація ПЗ для зниження затримки та високої ефективності використання пам'яті.
• Алгоритми: реалізація алгоритмів оцінювання стану (KF/EKF, PF, PMF, MAP estimation). Глибоких знань на старті не вимагаємо — важлива здатність до швидкого занурення.
• Проєктування архітектури: створення модульних, відмовостійких систем із використанням ООП, функціонального та подійно-орієнтованого (event-driven) підходів.
• Data-пайплайни: побудова пайплайнів обробки великих масивів різнорідних даних та потоків (відео, зображення, CSV, text, rosbag).
• Захист коду: впровадження заходів безпеки даних та систем обфускації (наприклад, pyArmor).
   

Необхідний досвід та навички:

• Python: впевнений інженерний рівень з фокусом на системних та архітектурних задачах.
• Математична база: фундаментальне розуміння та бажання заглиблюватися у складні алгоритми (state estimation, баєсівська фільтрація, MAP estimation).
• System Design: знання паттернів проєктування, розуміння принципів побудови складних систем.
• Конкурентність: практичний досвід роботи з multiprocessing, multithreading та async.
• Debugging: сильні навички налагодження та пошуку першопричин у складних системах.
• Автономність: здатність проєктувати та писати код самостійно, без критичної залежності від AI-інструментів.
   

Буде плюсом:

• Базовий C++ (або готовність швидко вивчити) для портування критичних модулів з Python.
• Робота з бібліотеками аналізу даних: NumPy, Pandas, GeoPandas.
• Досвід у проєктах з Computer Vision (CV) / ML.
• Робота з одноплатними комп'ютерами (NVIDIA Jetson, Raspberry Pi) та низькорівневими інтерфейсами (Serial/UART, SPI, I2C).
   

Що ми пропонуємо:

• Оформлення: прозоре та офіційне співробітництво через Дія.City.
• Локація та формат: зручний офіс у Києві (Правий берег) з усім необхідним.
• Здоров’я: медичне страхування та консультації психолога.
• Розвиток: компенсація навчальних курсів, доступ до знань, підтримка менторів та бадді.
• Відпочинок: 24 дні оплачуваної відпустки, додатковий вихідний на День народження, корпоративні події та подарунки.
• Оплата: ринкова компенсація та бонусна система.
