Break complex development efforts into manageable tasks and provide accurate estimates.
Conduct timely and thorough code reviews.
Lead by example in software development processes, engineering standards, and testing strategies.
Collaborate with Engineering, QA, DevOps, Product, and other cross-functional teams.
Support system configuration and application deployments, including occasional after-hours assistance.
Create and maintain technical, installation, operational, and troubleshooting documentation.
Mentor and support fellow engineers while promoting technical excellence and continuous learning.
Deliver high-quality work within established timelines and adapt effectively to changing priorities and technologies.

Required Qualifications

Experience with software architecture and design.
Experience with software requirements, debugging, testing, and documentation.
Experience with software build and deployment processes.
Experience working within Agile development environments.
Demonstrated ability to independently solve complex technical problems.
Strong analytical and problem-solving skills.
Strong written and verbal communication skills.
Ability to manage multiple priorities and consistently deliver results.
Demonstrated ability to collaborate effectively and provide technical leadership within an engineering team.

Why Join Q-Free?

Work on technology that improves transportation safety and mobility.
