Job description
Hardware & IoT Engineer based in Lagos (on the Island) Company: Picsible Technologies Ltd Product: BizOPD

Location:
Lagos, Nigeria Employment Type: Full-time

Salary:
₦250,000 – ₦350,000 About BizOPD: BizOPD is an operations platform built for businesses that handle custom orders and production. We help businesses stay organized, accountable and on schedule by giving them better visibility and control over their operations. We are expanding beyond software and into hardware and IoT products that connect physical business operations with BizOPD.

About the Role
We are looking for a Hardware & IoT Engineer to help us design, prototype, build and test connected hardware products. You will work across electronics, embedded systems, firmware, IoT connectivity and software integration. This is a hands-on engineering role for someone who enjoys turning ideas into working physical products. You will be involved in the full development process: Concept → Prototype → Testing → Iteration → Deployment You will work closely with our software and product teams to ensure that the hardware and software work together reliably. What You Will Do: Hardware & Electronics
• Design and prototype electronic devices and systems.
• Select appropriate microcontrollers, sensors, modules, power components and other hardware.
• Build and test prototypes using development boards, breadboards and PCBs.
• Work with components such as buttons, LEDs, displays, sensors, buzzers, NFC/RFID and other peripherals.
• Develop and maintain Bills of Materials (BOMs).
• Help transition successful prototypes into reliable, repeatable products. Embedded Systems:
• Develop firmware for microcontroller-based devices, particularly ESP32-class platforms.
• Write reliable device logic and event-handling systems.
• Interface with sensors and other electronic components.
• Implement device configuration and identification.
• Handle errors, reconnection, retries and unexpected device behaviour.
• Debug hardware and firmware issues. IoT & Connectivity:
• Build devices that communicate reliably over Wi-Fi, Bluetooth/BLE and other appropriate technologies.
• Integrate devices with APIs and cloud services.
• Work with HTTP/REST APIs and, where appropriate, MQTT or similar communication protocols.
• Design systems that can handle temporary connectivity problems.
• Implement appropriate local data handling and synchronization where required. Software Integration:
• Connect hardware devices to BizOPD and its supporting software systems.
• Work with software engineers to define device events, APIs and data structures.
• Ensure information generated by physical devices can be reliably communicated to the software platform.
• Troubleshoot issues across the hardware, network and software layers. Testing & Reliability:
• Test hardware and firmware extensively before deployment.
• Identify and resolve hardware, firmware, connectivity and integration issues.
• Test devices under real-world conditions.
• Investigate failures and improve system reliability.
• Document technical issues, testing procedures and solutions. Product Development:
• Turn product requirements into practical technical solutions.
• Research unfamiliar technologies, components and existing solutions.
• Evaluate different technical approaches and make recommendations.
• Build proof-of-concepts and prototypes quickly.
• Work with the product team to iterate based on testing and feedback.
• Contribute to the development of future hardware products. What We're Looking For: You should have practical experience with several of the following:
• ESP32 or similar microcontrollers
• Embedded C/C++
• Electronics and circuit design
• PCB design and development
• Wi-Fi and Bluetooth/BLE
• REST APIs
• MQTT or other IoT communication protocols
• Sensors and peripheral integration
• UART, I2C and SPI
• Git
• Hardware prototyping
• Embedded systems debugging Additional Experience That Would Be an Advantage
• OTA firmware updates
• IoT device provisioning
• IoT security
• Offline-capable systems
• NFC/RFID
• QR/barcode systems
• Raspberry Pi
• Linux-based systems
• Cloud-connected IoT systems
• Hardware manufacturing
• 3D printing or enclosure design
• Industrial automation
• Machine or equipment integration You do not need to have experience with everything listed above. Strong practical ability and the capacity to learn quickly are more important than matching every technology. The Kind of Person We're Looking For We're looking for someone who:
• Can take a problem and figure out how to build a practical solution.
• Is comfortable moving between hardware, firmware and software.
• Enjoys building and testing physical things.
• Can prototype quickly and improve based on what they learn.
• Understands the difference between a prototype and a reliable product.
• Can independently research unfamiliar technologies and components.
• Pays attention to details that affect reliability.
• Is comfortable troubleshooting problems from first principles.
• Can communicate clearly with both technical and non-technical team members.
• Is proactive and takes ownership of their work.
• Is comfortable working in a fast-moving startup environment. What Success Looks Like Success in this role means being able to take a hardware requirement from an initial idea through prototype, testing and deployment. You should be able to independently investigate technical problems, build working prototypes, integrate them with software, test them in real-world conditions and continuously improve the result. Your work will help us build reliable hardware products that make BizOPD more useful in the real-world environments where our customers operate. Why Join Us? This is an early-stage hardware opportunity within a growing technology company. You will have the opportunity to:
• Work on products from the ground up.
• Have significant ownership over technical decisions.
• Work across hardware, embedded systems, IoT and software.
• Experiment with new technologies and approaches.
• See your work move from prototype to real-world deployment.
• Work closely with a product and engineering team building a larger technology platform. Application: Please submit:
• Your CV.
• A brief description of a hardware, embedded-systems or IoT project you have personally built.
• Links to your GitHub, portfolio, project documentation or videos, where available.
• A short explanation of the technologies you used in your project. Candidates may be asked to complete a practical technical assessment involving hardware, embedded systems, IoT communication and software integration.

How to Apply
• Interested candidates should submit their CV along with a brief cover letter explaining why they are a good fit for the role to careers@picsible.com. Use the subject line: "Hardware & IoT Engineer – October 2026"
