Propulsion Engineer

Karman+ - Launching the Regolith Age
Denver, CO Full Time
POSTED ON 2/28/2025
AVAILABLE BEFORE 5/25/2025

Karman

We are inventors, designers, engineers, scientists, tinkerers, entrepreneurs, adventurers, artists, activists, global citizens, architects, musicians, builders, writers, athletes and space nerds. We partner with the best minds and most experienced teams across industry and academia, bringing together the knowledge, experience, and skills required to navigate our critical path.

Mission

We want to mine space resources from near-Earth asteroids to provide abundant, sustainable energy and resources in space and for Earth.

Vision

Asteroid mining has lived at the intersection of scientific research and popular culture for decades, with as many academic papers published as there are books, TV shows and movies about it.

Access to resources, with its finite nature and disparate distribution, plays an essential part in the geopolitical web of power and wealth. It has defined economic growth to such an extent that we have been using them as primary demarcation lines and identifiers in our history, from the stone to bronze and iron age to our current silicon age.

But our resources-driven growth faces a massive existential challenge, with climate change, ecosystem degradation and resource depletion demanding a complete reset. Humanity needs to shift global transportation, manufacturing, construction and energy onto a sustainable path.

Expanding beyond the Krmn line is where we believe transformative future growth and innovation will be found. Recent missions by NASA (OSIRIS-REx & DART) and JAXA (Hayabusa2) have firmly pushed the idea of using space resources from academic research into commercial opportunity.

We believe the Regolith Age , powered by abundant space resources, is an inevitability that we can accelerate.

We value these principles :

  • Diversity of thought . We believe that different perspectives drive better results. We aim to build diverse teams and a diverse company.
  • Ownership, feedback and accountability. Ideas improve through collaboration, discussion and iteration. Decisions don't follow the same pattern and revert to the mean when made in a group. We aim to have clear ownership, accountability for results and autonomy to deliver.
  • No silos. We build cross-functional teams to be able to deliver on our goals. There are no predefined lanes for people to operate in, information is pushed out across all teams to make sure we benefit from cross-pollination.
  • High talent bar, no a
  • holes. We optimize for potential and a growth mindset. We value experience, but only when balanced with self-awareness and first principles thinking.
  • Small is beautiful. The best results as well as the best work experience come from a small team of talented people working towards a common goal.

Position : Propulsion Engineer

Location : Denver, CO

Position Type : Full-time

Mission : High Frontier - Design, Integrate, Test, and Deploy the RCS and Main Propulsion Systems

Karman is a fast-paced space startup with a mission to redefine what's possible with a small, dedicated team working on groundbreaking projects. For our High Frontier mission, propulsion is crucial, and we're looking for a Propulsion Responsible Engineer to take ownership of the Reaction Control System (RCS) thrusters and the Hall Effect main thruster. If you're an experienced propulsion engineer who's ready to take end-to-end responsibility for critical subsystems, we want you onboard.

What it takes to be successful in this role :

As the Propulsion Responsible Engineer, you'll have full lifecycle responsibility for specific propulsion subsystems on the High Frontier mission. You'll design, analyze, integrate, test, and support the spacecraft's propulsion system to ensure precise maneuvering and reliable propulsion in space. This role requires deep technical expertise and hands-on problem-solving skills to drive subsystem success in a high-stakes environment.

This is an individual contributor role, focused on technical ownership rather than people management. You'll work closely with other teams and suppliers, making independent engineering decisions to keep the project on track. If you're passionate about spacecraft propulsion and thrive on solving complex engineering challenges, this role is for you.

Key Responsibilities

  • Lead the design, analysis, integration, testing, and deployment of specific propulsion subsystems.
  • Own every phase of the lifecycle-from concept and modeling, through testing and integration, to flight readiness and post-deployment support.
  • Make independent engineering decisions on subsystem architecture, component specifications, and design trade-offs to meet mission requirements within cost and schedule constraints.
  • Interface with other engineering teams (e.g., systems, structures, thermal) and departments (e.g., test, manufacturing, procurement) to ensure smooth integration of propulsion systems with the broader spacecraft.
  • Support the sourcing and procurement of propulsion components and propellants, working closely with vendors to ensure that all hardware meets mission specifications and integration requirements.
  • Identify, assess, and mitigate risks associated with the propulsion subsystem. Regularly review and adjust risk management strategies to address potential points of failure.
  • Ensure that all propulsion designs and components meet regulatory, operational, and quality standards, and act as the technical checkpoint for propulsion subsystems before major design reviews and integration milestones.
  • What You Bring

  • Foundational experience in propulsion engineering, with hands-on experience in spacecraft propulsion systems, ideally including electric (Hall Effect) thrusters.
  • Deep expertise in thruster design, fluid dynamics, thermal management, propellant handling, and the unique challenges of space-rated propulsion systems.
  • Strong problem-solving skills
  • Familiarity with project management tools and a disciplined approach to tracking and prioritizing tasks to meet project timelines.
  • Excellent communication skills, with the ability to articulate propulsion concepts and challenges to both technical and non-technical stakeholders.
  • Requirements

  • BS or MS in engineering, aerospace engineering, or related technical field.
  • Demonstrated experience with thruster design, fluid dynamics, thermal management, and space-rated propulsion systems.
  • Additional Information

    We Offer

    Our cash compensation amount for this role is targeted at $100,000.00 - $140,000.00 annually in this location. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amount listed above.
