Infrastructure Engineer for Innovation Lab
Summary
Builds and maintains the computing infrastructure behind QED's Innovation Lab R&D — managing cloud, private cloud, and bare metal servers, tuning GPU clusters for LLM workloads, and building monitoring/alerting — to help teams rapidly prototype digital health, agriculture, and education tools for Sub-Saharan Africa. Core stack: Linux, Kubernetes, containers, GPU systems, and infrastructure automat
QED () is a tech company focused on public health, agricultural development, and education in Sub-Saharan Africa. We build the digital infrastructure and AI used at the intersection of aid and scientific inquiry, including surveillance of HIV and malaria, and nutrient analysis of crops and soils, working at national-scale in several African countries. Our funding comes from multiple philanthropic and governmental organizations, including the Global Fund and the Gates Foundation.
We are looking for an infrastructure engineer to join our Innovation Lab, which focuses on rapid prototyping and R&D. We build new products to disrupt the status quo and remind everyone what tech was made for --- improving the lives of everyday people! The position can be remote, with periodic visits encouraged. Full-time engagement is preferred, but can start with part-time. Your responsibilities would include:
development and maintenance of computing infrastructure enabling our team to rapidly develop and deploy software prototypes, in both global and localized environments
management of servers and clusters, on public cloud, private cloud, and bare metal servers
design, configuration, assembly, testing, installation, and optimization of bare metal servers, including optimal configuration of GPU systems for tuning and deployment of large language models
physical inspection and technical advisory on constructing data centers in third-world countries with poor infrastructure, to help them achieve data sovereignty
construction of monitoring and alerting systems to rapidly detect and respond to lapses in performance
Desired skills include:
+3 years of experience
automation / declarative oriented mindset
broad knowledge of technology – including Linux internals, networking, databases, high level hardware performance, containers, performance tuning, security
experience with kubernetes
experience with Linux-based system administration for companies and data centers
strong background in software engineering, version control, writing readable code and tests, robust design, and basic data structures and algorithms
experience with optimizing GPU clusters
working proficiency in speaking, reading, and typing English
logical reasoning and ability to express ideas clearly, both orally and written
willingness and interest in working with people from other cultures
emotional resilience and social intelligence
and you have to care about the work that you do
Below are additional skills that are a bonus, but are not required:
+8 years of experience
knowledge of high performance computing (HPC)
practical electrical engineering knowledge, including power calculations and the selection and installation of batteries, inverters, solar panels, cables and trunking, satellite internet, and other hardware to make fully localized deployments possible
interest in traveling the world and engaging in at least short-term deployments to countries that require our assistance
experience with Terraform or similar IaaC
ethical hacking experience
experience with programming and/or math competitions
domain knowledge and/or interest in the sustainable development goals, particularly in public health, agriculture, and assisting developing countries
