Senior Software Engineer - Propulsion

Denver, Colorado

Start the Best Work of Your Career at Boom

At Boom, we built the groundbreaking XB-1 supersonic jet with a team of just 50 people—and the Overture supersonic airliner similarly was designed by an unusually small team. How can we do that? Great people—and lots of custom software. At Boom, software engineers work alongside the world’s greatest aerospace engineers to automate and accelerate hardware design and engineering—enabling small teams to accomplish big things quickly.

Symphony will be the fastest-ever development of a large–scale jet engine. In this role, you will be part of the propulsion team and work directly with the turbomachinery engineers designing the first ever purpose-built engine for supersonic passenger flight. If you don’t know how jet engines are designed and built, buckle in, you’re about to learn! The tools, code, and systems you build will accelerate design, development, and optimization of Symphony. And you’ll be right there when Symphony lights off for the first time—and when it climbs into the skies for the first time in just a few years.

You don’t need to have built a jet engine before—but you do need to be extremely passionate, curious, and a relentless autodidact. 

Role Overview

As part of the Propulsion Team, you will:

  • Learn everything about jet engines! How they work, how they are designed, optimized, and manufactured.
  • Live the Propulsion mission—partnering daily with engineers to uncover pain points and tear down bottlenecks.
  • Rapidly prototype features, gather feedback from tests and simulations, then mature them into rock-solid production systems.
  • Architect and automate end-to-end turbomachinery workflows that drive design, validation, and optimization at scale.
  • Build data architectures for instant, structured access to terabytes of simulation and test data.
  • Develop in-house simulation tools and data-management platforms when off-the-shelf solutions can’t keep pace.
  • Own configuration-management systems across inlets, engines, and nozzles—tracking every design revision.
  • Integrate legacy and commercial software into our custom stack for seamless, bulletproof processes.

The Ideal Candidate

  • Bachelor’s or Master’s in Engineering, Computer Science, or related field
  • Expert-level Python (Golang is a big plus)
  • Leverages AI to streamline workflows, tackle repetitive tasks, and amplify productivity. 
  • Proven AWS cloud-native development chops
  • Experience handling large datasets and architecting resilient systems
  • Deep familiarity with CI/CD pipelines, automation frameworks, and data workflows
  • Track record unifying legacy, enterprise, and custom tools into cohesive solutions
  • Comfortable with AI agents, automation, and data-driven pipelines
  • Obsession with testable, maintainable code and top-notch user experiences
  • Strong analytical thinker who can lead teams through complex, ambiguous challenges

What Will Set You Apart

  • Aerospace or hardware-software expertise—you’ve thrived where software meets high-stakes engineering.
  • Hands-on engine or propulsion analytics—you’ve wrestled with high-fidelity, multi-disciplinary turbomachinery data.
  • Fearless curiosity — blank slate or engine veteran, your hunger to learn and craft the right tools is what matters most.
  • Strong foundation in physics simulation and optimization modeling dynamic interactions and tuning parameters to hit design targets.
  • Demonstrated ability to ship high-impact, production-grade software under tight deadlines.
  • Proven collaborator—fast-prototyping and iterating with cross-functional teams to directly boost engine performance.

Compensation

The Base Salary Range for this position is $140,000 - $177,000 per year. Actual salaries will vary based on factors including but not limited to location, experience, and performance. The range listed is just one component of Boom’s total rewards package for employees. Other rewards may include performance bonuses, long term incentives/equity, an open PTO policy, and many other progressive benefits.

There is no set deadline to apply for this job opportunity. Applications will be accepted on an ongoing basis until the search is no longer active.

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

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.
