Backend Software Engineer- Platform

San Francisco, CA | Remote

About the Role

We are building the next-generation AI-powered platform and web application for easy and fast creation of audio and video content. Building a revolutionary way to record, transcribe, edit, and mix audio and video on the web comes with a series of unique technical challenges and requires solving hard and complex problems.

We are looking for an experienced software engineer to build a best-in-class video editing and streaming platform to power the core editing and AI functionality of the app.

What You’ll Do

  • Design, build, and optimize scalable backend infrastructure to process, store, and serve real-time media processing pipelines and AI inference workloads efficiently.
  • Collaborate closely with Product, AI Research, and Engineering teams to ensure our platform meets the evolving needs of advanced audio and video workflows.
  • Build cutting edge model training and evaluation infrastructure.
  • Evaluate, integrate, and optimize third-party AI vendor solutions, collaborating closely with Product Engineering and AI Research teams to enhance our AI capabilities and accelerate feature delivery.
  • Make high-impact architectural decisions that balance short-term goals with long-term scalability, while mentoring teammates and championing engineering best practices.

What You Bring

  • 5+ years of professional backend software engineering experience.
  • Experience with cloud infrastructure (GCP, AWS), modern data storage systems (S3, GCS, PostgreSQL, Dynamo/Bigtable), Linux, and data infrastructure (Airflow, Beam, Spark).
  • Expertise in modern backend languages and technologies, such as Python, Typescript/Node.js, Go, or similar.
  • Deep understanding of system design principles, performance optimization, and infrastructure automation (e.g., Temporal, Kubernetes, Docker).
  • Solid CS fundamentals, including data structures, algorithms, databases (Postgres, BigQuery), and familiarity with monitoring and observability tools (metrics and distributed tracing).
  • Strong written and verbal communication skills, along with good judgment in technical decision-making.

Nice to Have

  • Experience in AI and ML technologies (Pytorch, CUDA, distributed training).
  • Expertise in digital media processing, codecs, and streaming technologies (ffmpeg, WebRTC, HLS, MPEG-DASH).
  • Familiarity with GPU profiling, performance tuning, and optimization techniques.
  • Experience contributing to or engaging with open-source communities.

At our current size and stage, we embrace a flat organizational structure and value the expertise and contributions of every team member. As such, we have a unified job title for our engineering roles where everyone, including those with Staff-level scope, is considered a Software Engineer. While titles may not change, we are actively seeking Software Engineers with senior-or-higher-equivalent experience to join our team.

The base salary range for this role is $160,000- $240,000/year. Final offer amounts will carefully consider multiple factors, including prior experience, expertise, location, and may vary from the amount above.

About Descript

Descript is building a simple, intuitive, fully-powered editing tool for video and audio — an editing tool built for the age of AI. We are a team of 150 — with a proven CEO and the backing of some of the world's greatest investors (OpenAI, Andreessen Horowitz, Redpoint Ventures, Spark Capital). 

Descript is the special company that's in possession of both product market fit and the raw materials (passionate user community, great product, large market) for growth, but is still early enough that each new employee has a measurable influence on the direction of the company.

Benefits include a generous healthcare package, catered lunches, and flexible vacation time. Our headquarters are located in the Mission District of San Francisco, CA. We're looking to hire people who are local and able to join us at the office when needed. We're flexible, and you're an adult—we don't expect or mandate that you're in the office every day. But we do believe there are valuable and serendipitous moments of discovery and collaboration that come from working together in person. 

Descript is an equal opportunity workplace—we are dedicated to equal employment opportunities regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status. We believe in actively building a team rich in diverse backgrounds, experiences, and opinions to better allow our employees, products, and community to thrive.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
