Join the Revolution

Overview 

Co-founded by David F. Welch and Joy Laskar, AttoTude will develop advanced technology for next generation data center interconnects, demonstrating radical reduction in cost and power at ever increasing data-rates.  

The Opportunity  

The Engineering Team at AttoTude consists of a world class team working in a fast-paced and agile environment developing next generation modems for intra-DCI applications. The Hardware Engineer will be part of the system team and responsible for contributing to the development of novel MODEM technology and product realization. The ideal candidate will be prepared to work with early prototypes, establishing benchmarks and evaluation of product performance with rapid feedback to design teams. Performance characterization will include component and system level measurements, model matching, assessment of modem SNR and impairment penalties. The system team works closely with component designers and the candidate should anticipate frequent interactions on signal processing and performance issues. A key component of this role is the ability to understand and make tradeoffs to optimize the overall system performance.  

Roles and Responsibilities  

The successful candidate will play a pivotal role in helping to develop AttoTude’s next generation communications platform and will be responsible for maintaining a testbed for component and modem characterization and optimization. Your experimental data will fuel our designs, starting with prototypes and evolving into the final product. This requires ownership of the testbed, measurement metrology, optimization methods, and stabilization techniques. You will characterize hardware, analyze results and provide rapid feedback into hardware architecture and design teams. You will capture waveforms on a high-speed oscilloscope and perform off-line signal processing and measure bit-error rate performance in the presence of impairments to help diagnose issues.  

Through frequent interaction with other engineering teams, you will assist in developing algorithms for optimizing performance and transitioning realized performance gains to volume production.
