RF System Engineer

Austin is home to Optivers’ hardware research, development and manufacturing department. We build some of the world’s most competitive trading hardware using a wide variety of technologies, from fiber optics to custom silicon, from software to antennas - and everything in between.

We’re growing fast and are looking to expand our team with an experienced hardware engineer who deeply understands the complexities of designing and realizing high speed, high density systems and boards. Our systems push the limits of what’s possible, so we’re looking for creative thinkers who can oversee the big picture and who are not afraid to step out of their comfort zone and explore novel approaches.

At Optiver we pride ourselves on being real engineers, not just coders. Our engineers work closely with traders to identify the business problems we face and determine how they should be solved. We apply a disciplined and scientific approach. We engineer simple, well-architected solutions that meet the dynamic needs of our traders. Our passion is to solve problems which really matter to the business, and we take pride in the quality of our solutions.
