Remote Linux Jobs in Philadelphia, PA (NOW HIRING)

T38Fax isseeking a Linux savvy Systems Engineer to help us manage our data center infrastructure, build out our monitoring and DevOps infrastructure, and help us scale up ourSIP termination and origination services to keep ahead of the very strong demand for our product. Our fax customers use T.38 Fax Over IP (FoIP) to fax reliably over SIP, so we're basically very similar to a VoIP service provider, just without the voice part!

First, a Word About Fax

Fans of John Oliver's "How Is This Still A Thing" segments might be amused to learn that fax remains deeply entrenched in the way many companies transact their daily business. Indeed, it seems fax is still very much a thing! MarketWatch reports that the global fax market is expected to reach $2.4 billion by 2022, growing at a sustained annual growth rate (CAGR) of 11% since 2016. A 2017 report by IDC even put that number at 25% growth annually! It's especially surprising then, that most modern VoIP/SIP and cloud-based phone companies neither support fax over SIP nor understand how they might do so (until we show them how easy it is). Our fax-approved SIP trunks are ready to go today and fill a vital need in a growing and under-served industry that shows no signs of slowing down for many years to come.

COVID Update

We have always been a hybrid in-office/remote workforce with employees and contractors spread across several countries and many different timezones, and so we adapted quickly to a fully remote model during the early stages of the COVID-19 pandemic. We have begun planning our return to our brand new, never-occupied office in Conshohocken PA, and hope to get in there this summer. We do enjoy in-office work and although we do hope that many of our staff will rejoin us there, we have no plans to require in-office and this job can be fully remote for the right candidate, especially one that lives within driving distance of center city Philadelphia (our data center is at 401 N Broad St.) or near any of our planned expansion locations.

Our Story

Founded in 2016 and based in Conshohocken just outside of Philadelphia, PA, T38Fax provides fax-optimized SIP trunks to business customers within the US and Canada. We're similar to a Voice Over IP (VoIP) phone company, except our network is optimized for fax transmissions instead of voice. Our product is unique and in high demand, we're one of just a handful of companies that do this worldwide, and we have an exceptional reputation in the industry. In 2020, T38Fax was recognized by Inc. Magazine as one of the fastest growing companies in the US and by the Entrepreneurs Forum of Greater Philadelphia (EFGP) as one of the 100 fastest growing companies in the Philly metro area.

We remain small and agile, which makes this a fun, dynamic, and challenging place to work. The work environment is casual and, for the most part, informal. Expectations are high and excellence is encouraged and rewarded. We strive to make sure that we have a team-oriented group that can also work well independently. If you enjoy working in a high freedom, high demand environment with a small but talented group of people this may just be the job for you.

We offer a competitive benefits package including healthcare, a substantial number of paid days off (PTO), a generous profit-sharing plan, and access to our Flyers season tickets for yourself and a guest. We're a great group of people doing exceptional things for our customers and having fun doing it. Like any emerging growth company, this will be hard work, but more importantly, it will be fun and immensely rewarding. We think you already know if this is a position for you, and if so, we look forward to reviewing your application!
