    • Write and optimize frameworks and platforms that deal with bulk data acquisition
    • Tune our Linux environment for low latency and high throughput in a highly concurrent environment 

    SIG engineers are

    • Able to execute on ideas quickly
    • Committed to innovation
    • Focused on the entire technical stack with an eye for building a stable, scalable, optimized environment with minimized risk
    • Passionate about technology and interested in exploring new technologies to find the optimal solution
    • Strong object oriented software developers

    What we’re looking for

    • Strong C++ skills (Python development experience a plus)
    • Experience in concurrent programming and distributed system design
    • A general understanding of network protocols and the OSI model
    • Ability to context switch effectively in a fast paced environment driven by business needs
    • Ability to work as part of a team of developers and with the testing groups while also successfully managing individual tasks and projects with minimal guidance.
    • Keen attention to detail and accuracy.
    • Excellent communication skills that facilitate teamwork and interaction with colleagues and internal clients.
