Company: Sphinx Defense builds software to solve complex national security problems for America and its allies. We are building a vehicle-agnostic communication infrastructure for satellite operators. We're bootstrapped, profitable, and growing aggressively, with a strong focus on mission-driven engineering. Our culture values flexibility, autonomy, collaboration, and work/life balance. We prioritize building secure, automated, intuitive, and functional software.

Role: As a Senior Fullstack Engineer, you will design, develop, and maintain both the front-end and back-end components of our satellite communications platform. You'll work across the stack to build user interfaces, APIs, and underlying logic, contributing significantly to a product transforming space operations.

Responsibilities:
- Develop user-facing features and interfaces.
- Build reusable code and libraries for future use.
- Design and implement backend APIs and services (Python/Flask).
- Integrate backend systems with databases (PostgreSQL) and message queues (ActiveMQ).
- Ensure the technical feasibility of UI/UX designs.
- Optimize applications for maximum speed and scalability.
- Implement security and data protection measures across the stack.
- Collaborate with other engineers, product managers, and designers.
- Participate in code reviews and contribute to architectural decisions.

Technical Skills:
- Strong proficiency in backend development with Python/Flask.
- Experience with frontend technologies (specific frameworks not listed, but expect modern JS/HTML/CSS).
- Experience with relational databases, particularly PostgreSQL.
- Understanding of RESTful API design and consumption.
- Familiarity with message brokers like ActiveMQ.
- Experience with containerization (Docker) and cloud platforms (AWS).
- Knowledge of security best practices for web applications.
- Familiarity with version control (Git).

Ideal Candidate:
- Proven experience as a Fullstack Engineer, comfortable working across different layers of the application.
- Motivated self-starter who thrives in an autonomous environment.
- Passionate about building user-centric and functional software.
- Strong problem-solving skills and attention to detail.
- Excellent communication and collaboration skills.
- Interest in space technology and national security is a plus, but not required.
- Comfortable working in a remote or hybrid environment (this role is based in Colorado Springs).
- Eligible for US Security Clearance.
