$130k - $180kHarmonia | Revolutional
Senior Full Stack Engineer
Revolutional delivers advanced technology solutions and mission support to federal agencies across civilian, health, and national security environments. We apply modern capabilities, including AI/ML, cloud, cybersecurity, and IT modernization to solve complex challenges, enable faster and more secure operations, and drive measurable mission outcomes.
We are redefining how federal technology gets built and delivered by operating with a product mindset, prioritizing speed, ownership, and execution over bureaucracy.
Title: Senior Full Stack Engineer
Location: Remote
Terms: Full-time
Salary: $130,000 - $180,000 DOE
Clearance: Qualified candidates must be US citizens and able to obtain a minimum of a Public Trust clearance
Travel: 0-5%
This position supports Revolutional's customer, DHS ICE (Enforcement and Removal Operations – ERO), where critical mission systems are undergoing modernization. The current environment consists of large, complex legacy systems that manage operational workflows (e.g., processing, tracking, and managing encounters). These systems have evolved over time and often include layers of business rules, manual processes, and tightly coupled functionality.
The core challenge is not simply rebuilding these systems; it is:
- Understanding how they actually work in practice
- Identifying which functionality is mission-critical
- Eliminating unnecessary complexity
- Translating that functionality into a modern platform-based architecture
As part of this effort, DHS is adopting Palantir as a target platform for modernization. Revolutional plays a key role in bridging legacy systems and this new platform, ensuring accurate translation of functionality while improving system design.
No prior Palantir experience is required. Revolutional will provide training and certification to enable engineers to build effectively within the platform.
As a Senior Full Stack Engineer at Revolutional, you will own delivery across the stack while contributing to one of the most critical aspects of modernization: turning complex, legacy system behavior into clean, scalable software.
You will work across backend services, front-end components, integrations, and business logic, but your role goes beyond implementation. You will be expected to:
- Analyze ambiguous systems
- Break down complex workflows
- Identify flawed or unnecessary processes
- Help define how systems should work moving forward
You will operate in an environment where:
- Documentation is incomplete
- Requirements are not always well-defined
- Legacy behavior may not reflect optimal design
Success in this role requires systems thinking, strong engineering fundamentals, and the ability to operate in ambiguity.
Responsibilities:
- Design, develop, and maintain full stack applications supporting modernization of DHS ICE ERO systems
- Analyze legacy systems and workflows to identify core functionality vs. unnecessary process overhead
- Translate operational requirements into scalable, modern application designs
- Develop backend services, APIs, and integration layers connecting legacy environments to modern platforms
- Build and enhance user-facing components using modern front-end technologies
- Support the full SDLC: analysis, design, development, testing, deployment, and maintenance
- Troubleshoot issues across application, integration, and data layers
- Collaborate with stakeholders to clarify requirements and improve system behavior
- Participate in code reviews and uphold engineering best practices
- Complete Palantir training and certification (provided by Revolutional) and apply those skills in modernization efforts
What You Bring (Requirements):
Baseline Requirements:
- Bachelor's degree in Computer Science or related field (or equivalent experience)
- 7+ years of hands-on full stack software development experience
- Experience working in complex or enterprise system environments
- Ability to obtain and maintain required clearance
Technical Capabilities:
- Strong experience with Java and frameworks such as Spring Boot
- Experience designing and implementing RESTful APIs
- Experience with front-end technologies (JavaScript, React, HTML, CSS)
- Experience working with relational databases and data access patterns
- Ability to troubleshoot across multiple layers of an application stack
- Experience working in Agile or iterative delivery environments
Core Strengths:
- Ability to analyze and simplify complex systems and workflows
- Strong systems thinking and problem-framing capability
- Comfort working in ambiguous, poorly documented environments
- Ability to distinguish between essential functionality and legacy process bloat
- Strong ownership mindset and accountability for outcomes
- Effective communication with both technical and non-technical stakeholders
- High learning agility and willingness to adopt new platforms and tools
Nice to Have (Differentiators):
- Experience with legacy system modernization or transformation efforts
- Experience supporting federal or mission-driven environments
- Exposure to enterprise data platforms or large-scale system integrations
- Experience working in environments where requirements must be derived from real-world usage rather than formal documentation
