Job description

Senior Full Stack Engineer (FDE) - Clearance Required

Remote

Our mission is to be the technology backbone for strategic competition against peer adversaries. These missions – including intelligence, information operations, special activities, and perception management – are happening today and their success or failure will determine if we go to war tomorrow.

We've been on the front lines of these missions since 2019, and have grown to support a wide range of missions across all US service branches, multiple combatant commands, partner nations, interagency stakeholders, and the intelligence community. We deploy both hardware and software products to support people on the front lines that span collection, planning / assessments, and effects.

We've grown from $3M in run-rate revenue in 2021 to $80M in run-rate revenue today. We've been profitable since 2022 and have raised $91M in venture capital funding through Series B. We're valued at $1.5B as of 2025.

About the role

As a member of the product engineering organization, you will be embedded within one of our small teams, of 3-5 engineers, focused on delivering mission-critical capabilities into the hands of those who serve our nation. You’ll work directly with Product Managers, Designers, Mission and Engineers to define the product and technical direction for our product(s).

As a senior engineer, you are expected to take ownership and do whatever it takes to deliver game changing capabilities. You will drive key technical decisions and establish best practices for software engineering within your team. You’ll have a chance to build applications that leverage state of the art tools in Machine Learning and AI, to solve for mission-critical workflows.

What you’ll do

• Implement new features and user interfaces.
• Architect efficient and reusable front-end systems that drive complex web applications in environments with performance and resource constraints.
• Collaborate with Designers, Product Managers, Mission, and Software Engineers to deliver compelling user-facing products.
• Own and ship significant features along with architectural changes in collaboration with junior developers.
• Provide technical guidance and mentorship to peers.

Qualifications

• 4+ years of experience building responsive and performant web UIs. Mastery of front-end frameworks, like React, is a huge plus.
• 2+ years of full stack development, including familiarity with relational databases (like Postgres), caching technologies (like Redis), and object stores (like S3).
• Demonstrated knowledge of tools and best-practices for testing web applications is a huge plus.
• You must be a US resident or citizen.

What we offer

The salary range for this position is $150,000 - $215,000 + equity + 401K match. Within the range, individual pay is determined by experience, relevant education, and/or training.

We’re proud to offer competitive benefits that support our employees. Some key highlights of our benefits package include:

• Health, dental, and vision insurance
• 100% remote first culture. You can work from anywhere in the US and all full time employees have WeWork access
