We are building a real-time AI-powered desktop assistant that runs on-screen during sales calls — a live mission control layer that floats above Zoom, Google Meet, and similar tools. The product already exists and is actively deployed in enterprise environments on both Windows and macOS.

This is not a standard frontend role. We need a systems-level desktop engineer who understands operating systems deeply, knows how to write native modules, and can make software feel truly native — responsive, polished, and invisible in terms of resource usage. Windows is our primary platform, macOS is equally important for product quality.

You will own the desktop layer end-to-end: windowing architecture, IPC, audio capture, process management, native module development, enterprise deployment constraints, and OS-level integrations.

What You Will Do

• Own and evolve the existing Electron-based desktop application across Windows (primary) and macOS
• Build and maintain native modules (N-API) in Swift, Objective-C, C++, or Rust that extend Electron beyond what the web layer can provide
• Implement and optimize real-time audio capture during calls — handling system audio, microphone streams, and process detection for meeting tools like Zoom and Google Meet
• Design window management: always-on-top overlay behavior, transparent windows, multi-display support, and smooth lifecycle management
• Architect IPC boundaries between main process, renderer, and native modules to keep the app performant and stable during live video calls
• Solve enterprise deployment challenges: MDM compatibility, IT policy constraints, certificate signing, and managed device environments
• Drive performance, low CPU and RAM footprint, and stability — the app must run invisibly alongside resource-heavy tools
• Contribute to product experience and desktop UX, ensuring interactions feel native on both operating systems
• Own auto-update mechanisms, installers, and distribution pipelines across platforms

What We Are Looking For

• Strong experience building and shipping production desktop applications on Windows and/or macOS
• Deep understanding of Electron internals: main/renderer/preload architecture, IPC design, process lifecycle, and performance limits
• Hands-on experience writing native modules using Node-API (N-API), and fluency in at least one native language: Swift, Objective-C, C++, or Rust
• Solid understanding of OS-level concerns: permissions, audio APIs (CoreAudio on macOS, WASAPI/DirectSound on Windows), accessibility APIs, process management
• Experience deploying desktop software in enterprise environments — familiarity with MDM solutions, code signing, certificate policies, and IT-managed machines
• Ability to reason about memory, CPU, and resource usage and proactively optimize for low-footprint operation
• Strong engineering judgment, high ownership, and a track record of solving hard desktop engineering problems
• React experience is a plus — the UI layer uses React, but the systems work is the core priority
• Familiarity with enterprise Windows environments (Active Directory, Group Policy, IT management tooling) is a significant advantage

Nice to Have

• Experience with Tauri or willingness to evaluate it for future migration
• Knowledge of Zoom SDK, Google Meet integrations, or similar meeting platform APIs
• Background in audio signal processing or real-time audio streaming
• Portfolio of desktop applications demonstrating high UI polish and native feel
• Experience with security-conscious engineering: code signing, secure IPC, sandboxing

Tech Stack Context

Desktop: Electron + React + Native Modules (N-API). Backend (separate team): Python, FastAPI, Pinecone, GCP. The desktop app communicates with the backend in real time via WebSocket/streaming. You will not be responsible for backend work.

We Offer

• A high-impact role with real ownership of a core product layer used daily by enterprise sales teams
• Remote-first, async-friendly collaboration model
• Competitive compensation, discussed individually based on experience
• Stable long-term engagement with a clear product roadmap
• Engineering-driven culture: quality, performance, and correctness come first

Hiring Process

• CV review by CEO
• HR / introductory call
• Technical interview with engineering team
• Final interview with Hiring Manager
• Offer

Запрошуємо талановитого та досвідченого Backend інженера для довгострокової співпраці в AI-команду, яка працює виключно над власними продуктами. Ви працюватимете разом із нашим Product Architect, який має понад 20 років досвіду в сфері AI — ваш професійний ріст гарантований.
 

Про наш продукт:

Ми створюємо децентралізовану AI-екосистему, де десятки AI-моделей працюють як єдина система — від генерації відео до автономних бізнес-процесів. Наше бачення — дати кожному підприємцю інструменти, які раніше були доступні тільки великим компаніям.
 

Наш ідеальний кандидат:

• Має від 5 років комерційного досвіду в backend-розробці та звик працювати в startup / product середовищі.
• Впевнено працює з Unix/Linux (деплой, логи, процеси, базова мережа, troubleshooting).
• Має сильний досвід із Databases та SQL: транзакції, індекси, оптимізація запитів, performance.
• Розуміє та будував microservices: межі сервісів, інтеграції, ретраї, консистентність, спостережуваність.
• Не прив’язаний до одного стеку: має досвід у кількох мовах із нашого стеку — Rust, TypeScript (NestJS), Python — і вміє впевнено перемикатися між ними.
• Має досвід з Kubernetes та DevOps: деплой, дебаг, Helm, CI/CD. У нас це частина щоденної роботи кожного розробника, не окрема роль.
• Мислить системно й архітектурно: розуміє обчислення та систему на теоретичному рівні, бачить наслідки рішень і вміє пояснювати “чому так”.
• Активно працює з Claude Code. Це обов’язкова частина нашого стеку.
 

Буде плюсом: розуміння crypto/блокчейн-домену (транзакції/мережі/базова безпека), досвід з Dart.
 

Ми пропонуємо:

• Повністю віддалений формат роботи.
• Конкурентну винагороду.
• Можливість напряму впливати на продукт та архітектуру в інноваційній AI-сфері.
 

Як відгукнутися:

1. Надішліть скріншот або опис вашого Claude Code сетапу — як ви його використовуєте, які MCP, який воркфлоу. Це обов’язкова частина відгуку.

2. Якщо сетап нам підходить — запросимо на текстове технічне інтерв’ю в Signal англійською з нашим Product Architect.

Наш клієнт — українська технологічна компанія, яка створює власні IT-продукти та серійно виробляє високотехнологічне обладнання, що вже використовується у реальних сценаріях та зміцнює обороноздатність і технологічний потенціал України.
 

У компанії цінують швидкість, інженерну глибину та відповідальність за результат. Тут твоя робота має реальний сенс — код, який ти пишеш, безпосередньо впливає на поведінку фізичного апарату.
 

Що цікавого в цій ролі:

• Розробка core-логіки на Rust для БПЛА та автономних систем
• Робота з алгоритмами руху, навігації та планування траєкторій
• Інтеграція з автопілотами, сенсорами та системами позиціонування
• Оптимізація продуктивності та підвищення ефективності систем
• Вплив на архітектурні рішення та технічний напрям продукту
   

Що ми очікуємо від кандидата:

• Комерційний досвід розробки на Rust (Middle+ рівень) або підтверджений досвід швидкого освоєння нових мов
• Розуміння системної розробки: асинхронність, конкурентність, ефективність
• Досвід інтеграції з апаратними компонентами або зовнішніми системами
• Інтерес або досвід у БПЛА, робототехніці чи автономних системах
• Базове розуміння фізики руху: механіка, кінематика, аеродинаміка (на інтуїтивному або прикладному рівні)
• Знайомство з алгоритмами планування траєкторій та оптимізації
   

Буде плюсом:

• Досвід роботи з MAVLink
• Практичний досвід з автопілотами (ArduPilot, INAV або подібні)
• Embedded або low-level розробка
• Робота з телеметрією та системами позиціонування
• Освіта у сфері фізики, механіки або суміжних інженерних дисциплін
   

Чому ця роль цікава:

• Реальні інженерні задачі, де твій код впливає на фізичний продукт
• Високий вплив на продукт і результат
• Технічно сильна команда, яка любить інженерні виклики
• Глибоке занурення у сферу автономних систем
   

Умови: full-time, remote, графік 5/2. Готовність до інтенсивної та залученої роботи. Бронювання — за наявності належних військово-облікових документів.
