Senior Embedded Engineer / AI-Assisted Development

Unikie; Helsinki; On-site; EUR 75,000 - 95,000; Full time

Job summary

Unikie seeks a Senior Embedded Engineer specializing in AI-assisted development to optimize a constrained logger on legacy hardware such as STM32. You will extend data-logging capabilities and integrate a new probe while ensuring data integrity across the entire data chain.

You will design agentic workflows to manage multiple repositories and collaborate with testing strategies to validate performance, security, and reliability in a regulated product environment.

Qualifications

• Strong embedded C/C++ development experience.
• A track record with embedded Linux and real-time operating systems.
• Experience with constrained hardware such as STM32 and limited flash/memory.
• Familiarity with sensor/data-logger systems and environmental measurements is preferred.
• Knowledge of secure development: data integrity and tamper resistance in regulated environments.

Responsibilities

• Optimize existing logger codebase for legacy hardware with very limited flash memory.
• Integrate a new probe and extend data-acquisition and data-logging capabilities.
• Ensure end-to-end data integrity and protection across logger and data chain.
• Design agentic workflows to manage multiple repositories alongside embedded development needs.
• Collaborate with test strategies to validate functionality, performance, security, and reliability.

Job description

WE ARE LOOKING FOR Senior Embedded Engineer / AI-Assisted Development

We are looking for Senior Embedded Engineer / AI-Assisted Development to our team.

Key Responsibilities Include

• Optimise the existing logger codebase for legacy hardware, potentially based on an STM microcontroller, while working within severely limited flash-memory capacity.
• Integrate a new probe and extend the logger’s data-acquisition and data-logging capabilities to support it.
• Ensure end-to-end data integrity and protection against tampering, both within the logger and throughout the downstream data chain.
• Design and configure agentic workflows capable of managing multiple repositories alongside embedded-systems development requirements.
• Collaborate with existing test strategies and harnesses to validate functionality, performance, security, and reliability.

Required Qualifications

• Strong embedded C/C++ development experience.
• Hands‑on Embedded Linux and RTOS experience.
• Experience with STM32 or similar constrained hardware, legacy codebases, and limited flash/memory.
• Ability to work with sensor/data-logger systems, ideally temperature/RH measurement.
• Understanding of communication chains such as LoRa and cloud-connected embedded products.
• Practical secure‑development experience: data integrity, tamper resistance, and testing in regulated environments.
• Proven use of AI coding tools and agentic development workflows—e.g. Claude/LLM agents that inspect multiple repositories, implement changes, run tests, and refine solutions.
• Ability to take ownership of an ambiguous technical problem and establish a manageable AI‑assisted development process.
• Comfortable working directly with the customer and quickly internalising the product domain.
