Infinera – Why Work For Us?

At Infinera, we are redefining optical networking.

Infinera is enabling network operators to deliver vast amounts of bandwidth with greater ease. Whether for the long-haul core, metro, or emerging high-capacity metro cloud, Infinera Intelligent Transport Networks™ help carriers exploit the increasing demand for cloud-based services and datacenter connectivity as they advance into the Terabit Era.

Infinera Intelligent Transport Networks enable network operators to create rich end-user experiences based on efficient, high-capacity transport. Today, Infinera offers carriers, MSO/cable operators and Internet Content Providers (ICPs) the optical network platform of choice for ease-of-use, dramatic scaling, low cost of ownership and unparalleled reliability.

Today, over 135 customers in more than 72 countries rely on Infinera Intelligent Transport Networks to differentiate their services, protect their investment and lower operating expense as they scale their network.

Infinera is enabling the connected world by bringing automation, convergence and scalability to the optical network layer. Infinera Intelligent Transport Networks are designed to provide significant advantages over traditional systems, including:

  • Operating simplicity and cost savings: Intelligent software control allows end-users flexible management and control of their own network services and is designed to simplify network planning, engineering and operation; consume less power; enable simplified testing and improve system reliability;
  • Enhanced revenue generation: Infinera platforms lower the cost of optical to electrical to optical conversion, which enables our customers to access markets cost-effectively that had previously not been served due to cost constraints. We also believe that the our platforms enable communications service providers to add customers and provision new services more rapidly than traditional systems; and
  • Capital cost savings: Infinera’s platforms incorporate the functionality of more than 60 discrete optical components into a single photonic integrated circuit (PIC) pair, reducing capitalexpenditures and the physical space required for a given amount of optical network capacity.

At the core of the Infinera Intelligent Transport Network is a breakthrough semiconductor technology, the PIC. Basically a network on a chip, the PIC solves the cost, power dissipation, reliability and physical space issues in communications. The PIC provides massive WDM capacity in small power and space footprints to handle growing bandwidth needs, while allowing transport networks to scale in other dimensions. By solving the costly translation between the electrical and optical domains, long an albatross of network economics, the PIC enables DWDM optical transport networks to be more responsive to the digital services they carry.

The commercially-deployed, large scale PICs transmit and receive up to 500 Gigabits per second, or Gbps, of optical capacity and incorporate the functionality of more than 600 discrete optical functions into a pair of indium phosphide chips approximately the size of a child’s fingernail.

    Principal Optical Engineer Interview

    Anonymous Employee in Sunnyvale, CA
    Accepted Offer
    Positive Experience
    Difficult Interview


    I applied online. The process took 2+ weeks. I interviewed at Infinera (Sunnyvale, CA) in August 2015.


    Screening with HR and telephone interview w/hiring manager. I was local so I also met the hiring manger for lunch. Had a second telephone call with the director of group and was invited for an onsite interview. For the in person interview, they require you to give a 45 min talk on two subjects of your choice, 30 min in depth on one topic and 15 min on a second topic but not as deep. There is 1 hour allocated first thing in the morning for the talk so you will be peppered with questions throughout. About 12-15 ppl attended my talk. I was given a list of people who I would interview with that day and I looked them up on LinkedIn. They either had a PhD or a Masters degree in EE, Physics or Optics which felt intimidating since I knew these people would attend my talk. I think I put additional pressure on myself for the talk by looking them up and finding Stanford, MIT, USC and Berkeley among their alma mater. After the talk I had one on one interviews with 6-7 ppl throughout the rest of the day, 30 mins each. Many asked more technical questions about my talk and general technical questions in the area of Fiber optic communications. No mind teaser type questions which are no fun to solve during an interview. I also got the feeling they were evaluating my personality to see how I would fit in with the team. I was taken to lunch by the hiring manger and two other people. Here it was more seeing how I interacted with them with questions being general in nature such as my interests, hobbies and about my family etc... not really much technical discussion. The interview takes the whole day and is quite tiring, basically a full 9-5 day. I was exhausted by the end of the day. I think they generally like confidence in the candidate, the ability to communicate your ideas but I don't think you can fool all of them if you are not technically competent. One person commented that although he wasn't an expert in the topics I talked about he really enjoyed the way I connected my work to the work they do at Infinera. I think they all appreciated how I tailored my talk to them. It was a tough day but I could see how they value the hiring process to try to get it right.

    Interview Questions

    • Mainly questions about lasers, coherent communications and complex modulation techniques. Nothing someone in this field should be able to answer.   Answer Question


    The offer was quite nice, a bump from my current salary, a sign on bonus, performance bonus and RSUs. The compensation package was good so I accepted what they offered.
