• AWS or GCP at production scale — Docker, CI/CD, infrastructure ownership
• Fluent in Ukrainian or Russian — our core team communicates in these languages daily
• English C1 — clear communication with international stakeholders
• Operates without micromanagement — you drive your own execution

Strong advantage:

• Startup or scale-up background where you owned outcomes, not tasks
• SaaS or AI-native product experience end-to-end

• Systems thinking — you design for scale from the start

Core Technologies

Frontend: React, Angular, Next.js, TypeScript, JavaScript, Tailwind CSS Backend: Python, Node.js, REST APIs, GraphQL AI / Automation: OpenAI API, Anthropic API, AI agents, prompt systems, Cursor, workflow automation Infrastructure: PostgreSQL, Redis, Docker, AWS / GCP, CI/CD pipelines

Про нас:The Fourth Law (Четвертий Закон) — провідний український виробник технологій автономності для дронів. Рішення компанії кодифіковані за стандартами НАТО та застосовуються у понад 50 підрозділах СОУ і 20+ виробників дронів. Наші вироби носять імена українських діячів розстріляного відродження та шістдесятників — Василя Стуса, Олени Теліги, Миколи Зерова та Анатолія Лупиноса. У 2026 році компанія отримала відзнаку від DOU як найперспективніший проект у сфері оборонних технологій.

Місія ролі:Забезпечити функціональну еволюцію автономної робототехнічної платформи — від дослідження доцільності нових можливостей до їх повноцінного впровадження у продакшн. Твоє завдання — перетворювати інженерні гіпотези на математично валідовані, надійно інтегровані фічі, що працюють у реальних умовах на кастомному Linux-середовищі.

Основні задачі:
Повний цикл фічі: Ведення нових можливостей платформи від фази дослідження до production-ready коду — з відповідальністю за якість кінцевого результату для користувача.
Дослідження доцільності: Оцінка життєздатності нового хардверу (сенсори, NPU, модулі зв'язку) через технічний ресьорч, бенчмаркінг та зіставлення з системними вимогами.
Фізичне моделювання: Математичні розрахунки та базове фізичне моделювання (power/thermal budgeting, латентність сигналу, базова кінематика) для планування та валідації нових інтеграцій.
Оптимізація продуктивності: Дослідження системних bottleneck'ів та імплементація покращень для підвищення real-time продуктивності та ефективності використання ресурсів.
Архітектурна інтеграція: Впровадження нових фіч у встановлену архітектуру з використанням програмних патернів, що забезпечують підтримуваність та production-readiness коду.
Hardware/Software інтеграція: Забезпечення безшовного з'єднання нових компонентів з кастомним Linux-образом — робота на стику фізичного хардверу та аплікаційного рівня.
Agile-процес: Участь у Scrum-церемоніях з ownership над фічами — від першого розрахунку до фінальної доставки в спринті.

Досвід та навички, які ми шукаємо:

• Доведена здатність виконувати системні розрахунки та будувати моделі для прогнозування впливу нових фіч на мобільну робототехнічну платформу.
• Функціональне володіння C++ на рівні production-імплементації та сильний Python для ресьорчу, автоматизації й системної оркестрації.
• Глибоке розуміння архітектурних моделей та програмних патернів (Strategy, State, Observer).
• Впевнена робота у кастомному Linux-середовищі та розуміння взаємодії ОС з хардвером.
• Підтверджений досвід доведення складних фіч від фази концепту/розрахунку до задеплоєного продукту.

• Досвід роботи з MAVLink, ELRS, ROS/ROS2 та контролерами польоту PX4 або ArduPilot.
• Досвід моделювання та симуляції: MATLAB/Simulink, Gazebo або Python-based physics libraries.
• Розуміння вимог до запуску TensorFlow Lite або ONNX на edge-пристроях.
• Базове знайомство з Buildroot або The Yocto Project.
  
  Чому варто обрати нас:
  • Робота, яка матиме реальний вплив.
  • Ми створюємо продукти, які безпосередньо посилюють оборонний потенціал України.
  • Робота з топовими інженерами у сфері MilTech та автономності.
  • Офіційне оформлення трудових відносин в Дія.Сіті.
  • Можливість бронювання військовозобов’язаних працівників згідно з вимогами чинного законодавства.
  • Щорічна оплачувана відпустка — 24 календарні дні.
  • Для ветеранів передбачена додаткова оплачувана відпустка — 14 календарних днів.
  • Оплачувані лікарняні відповідно до законодавства.
  • Можливість компенсації витрат на навчання згідно з внутрішніми політиками.
    
    Ми шукаємо не виконавців, а однодумців, які поділяють наші цінності та готові будувати майбутнє українського MilTech.
