The posting

Description

Join Lumia, backed by Team8 and NewEra, and help us solve the next generation of AI security challenges at scale. Our product combines AI, security, endpoint and network technologies, and high-performance distributed systems.

You’ll be a core engineer on our platform, working across the stack. Your Windows kernel experience will help us build our endpoint agent, and you’ll also design and build backend services, shape our architecture and turn AI security ideas into production features.

Life at Lumia

We’re a small, early-stage team that takes the work seriously but not ourselves. We move fast, argue about architecture over lunch, celebrate wins together and help each other when things break. Everyone here has a real say, good ideas win no matter who they come from, and you’ll see your work in production quickly. If you love hard technical problems and want to have fun solving them with people you like, you’ll fit right in.

What you’ll do

  • Design, build and own features across the Lumia platform, from the endpoint to the cloud
  • Build and improve our Windows endpoint agent, including kernel drivers and user-mode services
  • Develop backend services and microservices that work with our endpoint and network components
  • Help shape our architecture, infrastructure and cloud deployment
  • Debug and optimize complex, high-scale systems, from crash dumps to distributed services
  • Work closely with product and research to turn AI security ideas into production features

Requirements

Requirements

  • 5+ years of hands-on software development, with strong C/C++ skills
  • 3+ years of Windows kernel driver development (WDK, KMDF/WDM)
  • Hands-on experience with network drivers, such as WFP callout drivers or NDIS filter drivers
  • Strong understanding of Windows internals
  • Solid understanding of networking fundamentals: TCP/IP, DNS, HTTP and TLS
  • Interest in working across the stack, including backend services in Go
  • Quick learner who does well in a fast-paced, changing environment
  • Self-motivated and detail-oriented, with a strong sense of ownership
  • A positive team player

Advantages

  • Experience with Go, microservices and cloud-native applications
  • Experience with high-scale distributed systems, Docker and Kubernetes
  • Experience with event-driven architecture (Kafka, RabbitMQ, NATS)
  • Background in endpoint security products such as EDR, antivirus, DLP or VPN
  • Experience with file system minifilter drivers, driver signing or the Microsoft HLK/WHQL process
  • macOS endpoint experience (Network Extensions, System Extensions)
  • AI and LLM experience, with an understanding of real-world applications

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
