What we expect

• Strong full-stack: Node.js / TypeScript + React + GraphQL in production
• UX sensitivity — you care how things feel
• AI is your default development mode (Claude Code, Cursor, or similar) — deep usage, not surface-level
• Product sense — you think about what to build, not just how
• High ownership: you ship, you fix, you improve
• Startup / small team experience

Nice to have

• Experience building AI agents, MCP servers, or autonomous dev workflows
• Dashboards, admin tools, B2B products
• GCP, PostgreSQL, React Native

About the Role:

We are looking for a firmware engineer who really knows how to work with modern hardware (ESP32-S3, PICAD-compatible boards) and Zephyr OS. The main task is to write stable, production-ready code for IoT devices at the “data logger / gateway” level: sensors, Modbus, LTE/Wi-Fi, OTA, local logic, energy saving.

No academic R&D - we need someone who can quickly produce a working product.

Responsibilities:

• Development of firmware under Zephyr OS for ESP32-S3 / ESP32-C6;
• Working with PICAD-compatible peripherals (sensors, interfaces, IO);
• Protocol implementation: Modbus RTU/TCP, UART, RS-485, SPI, I2C;
• Network stack configuration: Wi-Fi, LTE (via external modules), MQTT;
• OTA updates (MCUboot, Zephyr samples, custom circuits);
• Data buffering, local storage, fallback modes;
• Integration with backend API (REST/MQTT), queue/telemetry processing;
• Optimization of energy consumption and performance;
• Writing unit-/integration-tests, working with hardware-bring-up.

Requirements:

• Deep experience in firmware development in C/C++;
• Commercial experience with Zephyr RTOS is required (device tree, Kconfig, drivers, subsystems);
• Practical experience with ESP32-S3 / ESP32-C3 / ESP32-C6;
• Understanding MCUboot, partition layout, OTA pipeline;
• Ability to work with peripherals: UART, SPI, I2C, PWM, ADC, RS-485;
• Experience with Modbus (master/slave), preferably with real devices;
• Debugging experience: JTAG, OpenOCD, logic analyzer;
• Git, CI/CD, the ability to work in a normal product, not a "quick fix."

Nice to have:

• BLE (Zephyr BT stack);
• Python for tooling (scripts, tests, production tools).

We Offer:

• Working on a real IoT product (energy logger / gateway), which is already going into production;
• Opportunity for professional growth and career development;
• Vacation - 18 working days per year;
• Friendly working environment;
• Sick leave - 5 working days (without documents);
• Medical insurance.
