Embedded Software Engineer (Application) (d/f/m)

Join to apply for the Embedded Software Engineer (Application) (d/f/m) role at TK Elevator

Location: Madrid, Community of Madrid, Spain

Seniority level: Mid-Senior level
Employment type: Full-time

We are seeking a highly skilled and self‑motivated Applied Embedded Systems Engineer with deep expertise in modern C++ (C++17/20), Linux internals, and application‑level networking.

In this role, you’ll contribute to the development of robust Linux user‑space services and daemons, interface with devices through protocols like SPI, I2C, and GPIO, and help shape scalable and testable code using interface‑driven design and unit testing practices.

Your ability to navigate system‑level programming with tools like systemd, journald, and various Linux diagnostics will be key to ensuring performance and reliability.

Experience with REST, MQTT, and secure communication using TLS/mTLS will support cloud integration across our embedded systems.

Familiarity with Yocto, CI pipelines, and Agile workflows is a strong plus, as you’ll be working closely with a cross‑functional team to bring innovative and resilient solutions to life within TKE’s global product landscape.

What we expect

• Expertise in modern C++ (C++17/20), STL, and system‑level programming using POSIX APIs.
• Practical experience writing Linux user‑space services and daemons using systemd.
• Experience with user‑space device access (serial, I2C, SPI, GPIO).
• Familiarity with CMake‑based build environments and both modular and monolithic codebase structures.
• Comfortable with interface‑driven design, dependency injection, and unit testing with mocks.
• Deep understanding of Linux internals: processes, threads, IPC, filesystems, sockets, and signals.
• Hands‑on with systemd, journald, and networking tools (ip, dnsmasq, dhcpcd, etc.).
• Competence in diagnosing runtime behavior using gdb, valgrind, strace, lsof, top, perf, etc.
• Experience with logging infrastructure, log rotation, and structured logs.
• Familiarity with application protocols: REST, MQTT.
• Experience with TLS/SSL, mTLS, and certificate handling in embedded environments.
• Experience with publish‑subscribe patterns for loosely coupled service architectures.
• Familiarity with Git, CI pipelines, Docker, Bitbucket, and Jira workflows.
• Understanding of Yocto and ability to debug image integration issues and contribute to application‑layer recipes.
• Comfortable with Agile development and working in a multi‑disciplinary embedded team.

What we offer

• Health and Safety – Highest standards and a wide range of health promotion and healthcare activities.
• Flexibility – We support flexible yet regulated working hours and remote working options.
• Collaboration & Diversity – Collegiality is of huge importance; we treat everyone with respect and appreciation.
• Development – Individual support to help you get started as well as training and education programs.
• Creative leeway – We offer an environment in which you can try out new solutions in a no‑blame culture.
• Sustainability – We act with responsibility and environmental awareness.
• Work environment – We have modern workplaces and IT equipment, subsidised lunchtime meals in the canteen, free parking, and discounted public transport tickets.
