Software Quality Assurance Engineer - Telrex Careers

Telrex is the leading provider of VoIP call recording and monitoring software for IP PBXs. Telrex customers use our call recording and monitoring software for legal compliance, performance reviews, productivity measurements and to address security concerns.

Job Description:

Do you enjoy taking things apart to see how they work? Do you feel strongly that software should be reliable, fault tolerant, and function properly? Are you a magnet for software defects?

We’re looking for a clever, obsessively curious, and technically adept Software Test Engineer with a passion for product quality.

Our network-based VoIP call recording product is particularly challenging to test since we support so many different IP PBX systems and protocols. Many of our test scenarios require hard to automate actions like making actual phone calls and verifying recordings.

Duties & Responsibilities:

  • Craft excellent test cases to maximize test coverage and ferret out those hard to find bugs.
  • Write thorough bug reports that make developers wince at the bug, and then smile at your gift wrapped steps to reproduce.
  • Verify that bug fixes work as advertised and fix the whole problem.
  • Perform functional testing, regression testing, stress testing, stability testing, and generally put the hurt to the software before our customers do.
  • Communicate about defects, workarounds, and suggestions to the development and support teams, including an offshore team.

Skills/Requirements:

  • You must be a self-starter with excellent communication and analytical skills.
  • You must be able to handle concurrent projects with limited supervision.
  • You must be organized and detail oriented to manage your suite of test cases and awe us with your specific recipes for product meltdown.
  • Basic knowledge of networking (IP addressing, routers, switches, VPNs) and networking protocols (TCP/IP, UDP, DHCP). After all, VoIP phones are just little networked computers.
  • Strong understanding of using and configuring VMware virtual machines.
  • End-to-end understanding of QA processes, techniques, and best practices.
  • Test automation (like QTP) experience preferred, but not required.
  • Familiarity with Wireshark (formerly Ethereal) preferred, but not required.
  • Familiarity with VoIP systems and protocols preferred, but not required.

Credentials and Experience:

  • No college degree required—if you’re self taught and can demonstrate significant relevant experience, we would be happy to speak with you.
  • 2 years minimum work experience in Software Quality Assurance, preferably in an Agile development environment, and preferably testing client/server network applications.
  • Solid experience testing Microsoft Windows-based software applications.

This position is on site in Kirkland, Washington. Applicants outside of the Greater Seattle area will be considered, but relocation assistance will not be provided.

Longer term transitions from our QA team into our Software Development team are possible! For a well-qualified candidate with a basic background in computer programming, we are open to providing the training and mentoring required to become a successful software engineer at Telrex.

To apply, please email your resume and cover letter as an attachment to hr@telrex.com. Only e-mail inquiries will be considered, telephone inquiries regarding this opportunity will not be accepted.
