Job Description Code for Africa (CfA) has an immediate vacancy for a Senior IoT Software Engineer to join our sensors.AFRICA team to help build digital tools that transform how African cities work. The successful candidate will help drive pioneering projects, using the Internet of Things (IoT), including Africa’s largest network of low-cost ‘citizen science’ sensors. This includes improving sensors.AFRICA’s existing network of low-cost ‘citizen sensors’ that monitor air quality in five countries, as well as cutting-edge experimental water sensors that detect cholera and other contaminants, and novel hydrophone sensors to detect illegal dynamite fishing and coral bleaching in East Africa’s oceans. You will also help develop tools to analyse the imagery and data captured by drones/satellites to map settlements and better understand how to combat climate change. CfA is a non-profit technology R&D lab. While robust software engineering skills are required, no prior air/water/climate monitoring or urban development experience is required. The successful candidate will report to CfA’s sensors.AFRICA manager, and will also work with CfA’s wider technology, data, design and content teams in 21 African countries to build robust systems and infrastructures for our partners in watchdog civil society organisations, the investigative media and selected progressive government agencies. About the Role The successful candidate will join CfA’s sensors.AFRICA team as a Senior IoT Engineer to help shape its hardware/software choices and to lead development of new digital services. The team currently consists of a senior strategist and mid-level hardware/software engineers who have successfully steered sensors.AFRICA through a series of proof-of-concept pilot projects deploying CfA’s own prototype low-cost sensors, as well as working with partners such as the Kenyan National Bureau for Statistics (KNBS) and the South African Medical Research Council (SAMRC) to experiment with new ways to use air sensors to create actionable insights/data. The success of these early projects has prompted CfA to expand the team, ahead of planned rollout of wider citizen-driven sensor networks in key African countries, as well as new research partnerships that will explore who to use low-cost sensors to give communities early warning for cholera outbreaks and other public health emergencies. The expanded sensors.AFRICA team will be part of a multinational and multilingual team across the continent, and will be comfortable using digital collaboration tools to create open source software/hardware products for a global audience and international partners. Applicants should possess knowledge of engineering principles and practices, and the fabrication processes (such as 3D printing) to turn designs into devices. Applicants should also be comfortable computing complex engineering calculations, quickly and accurately, while also performing detailed analysis of designs, specifications, and plans, and establishing and maintaining effective working relationships with collaborating partners both within CfA and outside of the organisation. Responsibilities Your daily responsibilities will include: Work as part of the technology team in shaping the software and front-end web-tools architecture and development processes, working within coherent roadmaps, ensuring quality control and helping to proactively problem-solve. Develop and review firmware written in C, C++ and Python. Review PCB and mechanical designs. Requirements and design specification creation. Improve and optimise the ongoing performance, scalability, and reliability of our software systems (and documentation) given the growing size of our sensor networks. Shape our strategies for standardised sampling and measuring standards, equipment protocols, and data management systems. Oversee consistent and proactive calibration and maintenance for all deployed monitoring equipment, including innovative ways to support volunteer (non-technical) custodians of the equipment at schools, environmental organisations, etc. Participate in stakeholder consultations or internal strategic discussions, to help non-technical partners understand what is possible and now best to use the technologies to achieve actionable insights. Requirements Minimum requirements include: 5+ years of industry experience in Software Engineering and embedded software development. B.Sc / B.Eng in Computer Science, Computer Engineering or equivalent practical experience. Experience reading and interpreting data sheets and electrical schematics. Strong debugging and analytical skills. Demonstrated experience in revision control using Git and git workflows. Experience leading technical projects. Experience in leading IoT projects will be a plus. Experience in embedded real-time software engineering, e.g. FreeRTOS Experience designing reusable libraries and SDKs. Experience with the full lifecycle of an IoT device. Ability to develop firmware in C++, C, and Python programming languages. Working knowledge of modern software development practices and technologies such as Agile methodologies and DevOps. Experience working with and managing columnar and time-series databases for real-time data and analytics. Experience working with metrics and monitoring tools such as Grafana. Self starter with the ability to work effectively in teams across internal and external organisations and virtual teams. Language and Location Requirements: Location: CfA’s main sensors.AFRICA lab is located in Nairobi (Kenya), but CfA also has additional labs in Abuja (Nigeria), Cape Town or Johannesburg (South Africa), Dar es Salaam (Tanzania), and Lagos (Nigeria). The role can be performed remotely, and CfA will therefore consider exceptional applicants from across Africa. Primary language: English Preferred but not required: French, Amharic or Arabic. What We Offer A competitive salary, subject to experience, with opportunities for performance-based growth, both in terms of career path and public stature. A dynamic workplace, with a transnational team, occasional international travel, and generous vacation benefits. Ongoing opportunities to learn new cutting-edge skills and techniques/technologies to future-proof yourself in a rapidly evolving industry. A chance to shine on a global stage, writing for international audiences and interacting with colleagues around the world. Apply Here
