Job Offering Company Introduction

Keymech is a design and product development company operating in the field of mechanical engineering, electronics, and software development. Founded in 2022, the company works with clients who require complete product design solutions, from early concepts to working prototypes and production-ready deliverables.

Keymech focuses on building products rather than offering isolated services. Its work covers mechanical design, electronics development, firmware programming, prototyping, and testing. This multidisciplinary structure allows the company to handle full product cycles without separating mechanical and electronic domains. Clients can approach the company with a concept and receive manufacturing-ready documentation, firmware, and circuit designs as part of a comprehensive package.

On the mechanical side, the company works with CAD modeling tools such as SolidWorks, CATIA, Creo, and Fusion 360. The team handles product modeling for 3D printing and large-scale manufacturing. It also performs finite element analysis using tools like ANSYS, Abaqus, and SolidWorks Simulation. For fluid dynamics projects, the company uses ANSYS CFX, ANSYS Fluent, and Star CCM+. Rendering and product visualization are managed using KeyShot. Mechanical documentation includes detailed manufacturing drawings and design calculations.

In electronics development, Keymech handles circuit design, PCB design, and firmware programming. The team works with controllers such as Arduino, Raspberry Pi, ESP modules, PIC, 8051 microcontrollers, PLC systems, and DSP kits. Sensor integration projects include infrared proximity sensors, ultrasonic sensors, acoustic sensors, tactile sensors, humidity sensors, and PIR modules. Peripheral modules include GSM, GPRS, touch screens, and wireless communication systems such as Bluetooth, BLE, WiFi, and LAN.

The company’s approach to product design follows a structured workflow. It begins with concept sketches, moves into detailed 2D and 3D CAD modeling, and then proceeds to prototyping when required. The final stage includes testing, validation, and preparation for deployment or manufacturing. In certain cases, Keymech also connects clients with manufacturers to streamline production.

Keymech operates in the design services industry and maintains a strong focus on practical engineering outcomes. Its specialties include robotics, enclosures, design for manufacture, 3D printing, rapid prototyping, IoT devices, industrial design, consumer electronics, PCB design, embedded systems, app development, firmware development, and mass manufacturing design support.

The company places emphasis on communication, honesty, and accountability. Because product development often requires iterative refinement, collaboration between team members is essential. Engineers at Keymech are expected to work across disciplines and understand how mechanical decisions influence electronics and vice versa.

Keymech is currently hiring an Embedded Systems Engineer for its Wah Cantt office. This role is intended for candidates with foundational experience in embedded systems who are ready to work on hands-on hardware and firmware development projects. The position offers exposure to real-world product prototypes, IoT systems, and integrated hardware solutions.

This hiring reflects the company’s continued expansion in embedded and connected device development. Candidates who join the team will be directly involved in building functional systems that combine sensors, controllers, communication modules, and automation logic.

Job Description

The Embedded Systems Engineer will be responsible for developing embedded software and supporting hardware integration projects involving ESP32 and Raspberry Pi-based systems.

The role includes writing firmware and application-level software primarily in Python, C, C++, or through the Arduino IDE. Code development should follow clean and modular practices, allowing for future expansion and maintainability. The engineer will design and structure programs to handle sensor inputs, actuator outputs, and communication protocols.

One of the central responsibilities involves building and testing functional prototypes. These prototypes may include sensor arrays, display interfaces, motor control modules, wireless communication systems, or data acquisition units. The engineer will work closely with both hardware and mechanical teams to ensure that prototypes perform reliably.

The position requires strong familiarity with ESP32 modules and Raspberry Pi boards. Tasks may include configuring GPIO pins, managing serial interfaces such as UART, implementing I2C and SPI communications, and integrating external peripherals.

Debugging hardware-software interactions is an essential part of the role. The engineer must identify communication mismatches, timing errors, voltage issues, and logic faults. Real-time troubleshooting is required when prototypes behave unexpectedly.

The role also covers connected systems and automation logic. This includes implementing remote monitoring features, integrating IoT communication layers, and ensuring data collection systems operate accurately. The candidate may develop systems that transmit sensor data over WiFi or Bluetooth for monitoring or analytics.

Collaboration with the R&D team is critical. The Embedded Systems Engineer will participate in experimental development, concept validation, and iterative design improvements. Engineers are expected to propose practical solutions rather than only executing assigned tasks.

The job also requires reading and interpreting circuit schematics to ensure firmware aligns with hardware design. Knowledge of voltage levels, signal flow, and component functionality is necessary when debugging.

Exposure to Linux environments is valuable, particularly for Raspberry Pi systems. The candidate may need to navigate terminal commands, configure services, and manage dependencies.

Version control practices such as Git usage are encouraged. Managing code revisions and collaborating through shared repositories ensures organized development workflows.

The engineer must be capable of working independently on assigned modules while maintaining communication with the broader team. Time management and structured debugging practices are important.

Overall, the job focuses on hands-on embedded product development, from firmware coding and peripheral integration to testing and iteration.

Eligibility Criteria

Applicants should have one to two years of experience in embedded systems or electronics projects. Academic projects or serious personal projects are acceptable as part of this experience.

Strong programming skills in Python and/or C/C++ are required. Candidates should demonstrate an understanding of structured coding practices.

Hands-on experience with ESP32 and Raspberry Pi platforms is essential. Applicants must understand GPIO configuration, serial communication, and peripheral interfacing.

Knowledge of communication protocols such as I2C, SPI, and UART is necessary. The candidate should be able to implement and troubleshoot these interfaces.

Understanding circuit fundamentals and sensor integration is required. Applicants should know how to interpret circuit diagrams and identify components.

Familiarity with Arduino IDE and microcontroller firmware development is preferred.

Experience working on IoT applications or connected devices is considered an advantage.

Exposure to Git or other version control systems is beneficial.

Knowledge of Linux operating systems and terminal usage is desirable.

Soft skills are also important. Candidates should show curiosity, attention to detail, and a problem-solving mindset. Collaboration and communication skills are essential.

Applicants should be self-motivated and willing to take initiative in experimental and product-oriented projects.
