Job Title: Embedded Frontend Engineer

Location: Lagos, Nigeria

Job Description

• We are seeking a versatile Embedded Systems Front-End Engineer with strong skills in embedded UI development, CAD-based hardware/mechanical design, and Figma UI/UX prototyping to join our team “Automation & Integration Engineering Team”.
• The ideal candidate will bridge the gap between device hardware design, embedded software front-ends, and user experience design for companion applications and dashboards.
• This requires a multidisciplinary engineer who can design interfaces for embedded devices, prototype user experience in Figma, and contribute to CAD models for enclosures and hardware integrations.

Responsibilities
Embedded Front-End Development:

• Design and implement graphical user interfaces (GUIs) for embedded systems (LCDs, TFTs, OLEDs, touchscreens).
• Develop front-end applications in C/C++, Python, or Java (for embedded Android-based HMIs). Use frameworks such as LVGL, Qt for Embedded, or TouchGFX to create optimized interfaces for low-power devices.
• Integrate UI with real-time data from sensors, actuators, and communication protocols (UART, SPI, I2C, CAN, RS485, Modbus, MQTT).

UI/UX Design (Figma):

• Design intuitive, user-friendly layouts and workflows in Figma for embedded GUIs and companion mobile/web applications.
• Develop wireframes, prototypes, and design systems to guide both embedded and mobile UI implementation.
• Collaborate with firmware and mobile app developers to ensure design fidelity and usability across platforms.
• Conduct user research and usability testing to refine UI/UX designs for embedded systems and dashboards.

CAD & Hardware Integration:

• Create and refine 3D CAD models for device enclosures, housings, and mounts using SolidWorks, Fusion 360, or AutoCAD.
• Collaborate with PCB and hardware teams to ensure seamless integration of displays, connectors, and user-interface hardware.
• Support mechanical design reviews, focusing on manufacturability, ergonomics, and usability.
• Prototype and iterate designs via 3D printing, CNC machining, or other rapid prototyping methods.

Cross-Functional Collaboration:

• Work closely with firmware, hardware, and product teams to deliver integrated solutions.
• Contribute to system-level design decisions, balancing UI/UX needs with hardware and performance constraints.
• Participate in end-to-end product lifecycle from concept → design → prototyping → production.

Requirements
Education:

• Bachelor’s Degree in Electrical/electronic Engineering, Computer Engineering, Mechatronics, or related field. Master’s degree is a plus.

Experience:

• 1 - 4 years of experience in embedded systems UI development
• Demonstrated ability in Figma for UI/UX design (with a portfolio of wireframes, prototypes, or dashboards).
• Hands-on experience with CAD tools (Fusion 360, AutoCAD, or equivalent).

Technical Skills:

• Embedded programming skills in C/C++, Python, is a plus o Familiarity with UI frameworks for embedded devices (LVGL, TouchGFX).
• Strong Figma design and prototyping skills (including design systems, interactive flows).
• Knowledge of PCB layout considerations and integration of hardware components with enclosures.
• Understanding of embedded hardware design fundamentals (MCUs, displays, sensors, power).

Soft Skills:

• Strong design-thinking mindset with an eye for detail.
• Excellent communication and documentation skills.
• Ability to work across software, hardware, and design disciplines.

Preferred:

• Experience designing IoT companion apps/dashboards (mobile or web).
• Familiarity with industrial design principles (ergonomics, materials, usability).
• Understanding of cloud integration and edge-to-cloud UI design.
• Experience in usability testing and design iteration cycles
