Systems Engineer

Project Need and Scope

Is your view of Systems Engineering that no job is complete until it’s automated, monitored and documented? Is your passion for automation matched by your passion for large scale? Do you love digging into the code and finding its innermost secrets? Do you habitually check all your changes into a revision control system? If this describes you, Proximic may just have the challenge you’re looking for.

We looking to hire passionate Systems Administrators to help build out our platform and ensure that we can continue to scale beyond the hundreds of thousands of requests per second that we currently handle. Obviously, at these scales, automation is key so your knowledge of Puppet, Python and shell will be made use of on a daily basis as will your troubleshooting skills while you work with the team to tune our Java stack. While the frontend systems are colocated to handle the sub 10ms latency requirements, our backend is almost exclusively in AWS so a strong knowledge of API driven systems administration is preferred.

This position is full-time and based in our main office in downtown Palo Alto, CA. Applicants must be suitable for immediate employment.

Responsibilities

• Constantly improve the maintainability and scalability of the production environment.
• Work with engineering to design solutions that scale and ensure new services will be operationally maintainable.
• Ensure Proximic services are always available and operating optimally.
• Monitor all the nooks and crannies of applications so that issues are caught by the team rather than partners and customers.
• Document everything, no because you need to, but because you understand how much it improves your life and that of your team mates.
• Participate in code reviews where your thoughtful feedback will help the team continuously improve.

Required Qualifications

• Passion for building scalable and maintainable infrastructure in a team.
• Knowledge of UNIX/Linux core technologies and an ability to describe fundamental kernel internals.
• Knowledge of fundamental networking technologies and their application.
• Programming experience in a common administrative language such as Python, Perl or Ruby.
• Strong troubleshooting abilities at both the systems and application levels.
• Experience building processes which help teams go faster rather than being miring them in bureaucracy.
• Written and oral communications skills that allow you to effectively present ideas to the team and management.

Preferred Qualifications

• Advanced Python and/or Java programming.
• JVM internals and tuning.
• Experience in multi-tier application architecture.
• API driven systems administration (AWS, Rack Space, Joyent, home grown).
