Senior DSP Software Engineer

Last updated 26 days ago
Location:Redmond, Washington
Job Type:Full Time

In Mixed Reality, people—not devices—are at the center of everything we do. Our tech moves beyond screens and pixels, creating a new reality aimed at bringing us closer together—whether that’s scientists “meeting” on the surface of a virtual Mars or some yet undreamt-of possibility. To get there, we’re incorporating groundbreaking technologies, from the revolutionary Holographic Processing Unit to computer vision, machine learning, human-computer interaction, and more.

We’re a growing team of talented engineers, program managers and artists putting technology on a human path across all Windows devices, including Microsoft HoloLens, the Internet of Things, phones, tablets, desktops, and Xbox. Our team has people from a wide variety of backgrounds, identities, previous work histories, life experiences, and we are eager to maintain and grow that diversity. Our varied backgrounds and unique experiences enable us to be better at building the best solutions for our customers and make for dynamic and joyful collaborations with colleagues!

If you are passionate about groundbreaking Mixed Reality technology and want to work on a team dedicated to a culture of inclusion, growth mindset and collaboration, we need you!

Team Overview

Immersive digital experiences envelop people and blur the lines between what is real and what is virtual. For audio immersion, technologies such as spatial audio and virtual acoustics provide the tools that when applied to augmented and virtual reality experiences give critical cues that humans use to locate and experience virtual content.

Microsoft's investments in immersive audio are advancing the state of the art in spatial audio and acoustics. Through tight collaboration between research and product development, Microsoft has demonstrated a strong leadership in the industry for both publishing research papers as well as integrating the latest immersive audio technology into innovative products such as HoloLens, Windows Mixed Realty and video games.


Join Mixed Reality and help create the future of Microsoft’s hardware and software businesses. For this opening, we are looking for an DSP Software Engineer. The candidate must have demonstrable experience implementing algorithms for real-time signal processing. He or she will work with a multi-interdisciplinary team in applied research and product incubation, with the goal of creating the next generation of devices and user experiences.
