System Translation: Work with system engineers to translate complex technical RF requirements and deliver top-tier software solutions that are technically sound, feasible, and aligned with business objectives.
Comfort with Ambiguity: Thrive in a fast-paced startup environment with shifting priorities. Maintain a pragmatic, solutions-oriented outlook and balance speed versus quality trade-offs effectively. Bring structure and clarity when navigating situations with high uncertainty.
Technical Communication: Communicate complex software concepts effectively to both internal and external stakeholders, including executive audiences.
Mentoring: Provide technical guidance to software engineers, particularly in areas like improving engineering processes, ensuring software quality and security standards, and ensuring system reliability and performance.

Qualifications

Minimum of 7 years of Python, Go, Rust, C++, or similar related experience and 10+ years of general software development experience
Experience designing and building real-time and near-real-time systems, including ML inference
Experience with distributed systems, databases, and messaging systems
Strong Linux knowledge with hands-on experience.
Strong knowledge of software architecture principles and ability to contribute to architectural discussions
Ability to independently own solutions from design through implementation and iteration
Comfortable working with ambiguity, shifting priorities, and speed-versus-quality & coverage trade-offs.
Strong judgment, decision-making, and problem-solving skills
Experience working in a leadership or senior engineering role
Excellent written and verbal communication skills, capable of engaging with both technical and non-technical stakeholders
Curiosity and willingness to learn domain-specific telecom and RF related technology.

Preferred Skills

Experience with technologies such as Kubernetes, Helm, Docker, Kafka, or NoSQL databases (e.g., MongoDB, InfluxDB)
Familiarity with data/ML techniques and libraries such as NumPy and SciPy is a plus.
Familiarity with modern front-end technologies and frameworks, including JavaScript/TypeScript, Angular, React, or Vue.js.
Experience working with modern deployment techniques and practices, such as CI/CD pipelines and deployment automation
Understanding of RAN (Radio Access Network) concepts, including cells, sites, controllers, and topologies

Additional Information Why Join Us

Dynamic Team: Collaborate with passionate experts driving real innovation in the telecom space
Career Growth: Work on high-impact problems with real ownership and visibility
Meaningful Work: Help shape the next generation of ML-driven network analytics
Attractive Benefits: Competitive salary, stock options, and a flexible work environment

Do you have the technical chops and product sense to help shape the future of wireless automation? Apply now - your next big opportunity starts here.
