Principal Dsp Engineer

**Meet the Team***:
Join our team at Acacia, where we design advanced optical transceivers for high-speed fiber optic transmission in data centers and telecommunication networks. We're seeking enthusiastic, experienced individuals to work on the forefront of fiber optic technology. You'll be part of the team developing Digital Signal Processing (DSP) and Forward Error Correction (FEC) algorithms for our optical transceivers' Application-Specific Integrated Circuits (ASICs). Collaboration with colleagues from the DSP and ASIC teams is key to optimizing performance and power efficiency. You'll contribute to system design, develop architectures, and support ASIC design and verification. Work closely with colleagues across various fields and gain diverse knowledge in optical system testing, analog components, modeling, and more.

**Your Impact***:
With your expertise in DSP for coherent optical transceivers, FEC, and modeling, you help the team to develop the next generation of low-power and high-performance coherent transceivers. Here are some examples of possible topics:

- Invent, simulate and validate new DSP or FEC algorithms (both in floating-point and fixed-point precision) to improve performance and functionality or lower power consumption
- Test and optimize these algorithms on actual hardware and correlate performance with previous simulations
- Develop models of analog RF and optical components and evaluate system performance with these models
- Analyze performance of developed transceiver modules and update models and simulation environments to accurately match the measured results

**Minimum Qualifications**:

- At least 10 years of industry experience in related fields.
- Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for optical communications.
- Proficiency in modeling communication systems.
- Programming experience in C/C++, Python, Matlab, or similar languages.
- A master's or Ph.D. degree in mathematics, physics, or electrical engineering is highly recommended, although not strictly required.

**Preferred Qualifications**:

- Familiarity with C++, Linux, and version control systems, specifically SVN and Perforce.
- Experience with Verilog or VHDL, and/or collaboration with ASIC designers.
- Experience with coherent and direct-detect optical communication systems
- Practice effectively presenting technical information to colleagues.

**#WeAreCisco***:
WeAreCisco where every individual brings their unique skills and perspectives together to pursue our purpose of powering an inclusive future for all.

Our passion is connection—we celebrate our employees’ diverse set of backgrounds and focus on unlocking potential. Cisconians often experience one company, many careers where learning and development are encouraged and supported at every stage. Our technology, tools, and culture pioneered hybrid work trends, allowing all to not only give their best, but be their best.

We understand our outstanding opportunity to bring communities together and at the heart of that is our people. One-third of Cisconians collaborate in our 30 employee resource organizations, called Inclusive Communities, to connect, foster belonging, learn to be informed allies, and make a difference. Dedicated paid time off to volunteer—80 hours each year—allows us to give back to causes we are passionate about, and nearly 86% do

U.S. employees have **access** to quality medical, dental and vision insurance, a 401(k) plan with a Cisco matching contribution, short and long-term disability coverage, basic life insurance and numerous wellbeing offerings.

Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components. For quota-based incentive pay, Cisco typically pays as follows:
.75% of incentive target for each 1% of revenue attainment up to 50% of quota;
1.5% of incentive target for each 1% of attainment between 50% and 75%;
1% of incentive target for each 1% of attainment between 75% and 100%; and once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.

For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
