Note: The job is a remote job and is open to candidates in USA. Redhorse Corporation is a solution-driven company delivering data insights and technology solutions critical to U.S. national interests. They are seeking a Senior Everything Engineer with a Backend focus to modernize a mission-critical legacy system managing billions of dollars in international security cooperation. The role involves developing domain services, business-rule archaeology, and ensuring financial-grade correctness in a complex technical environment.
Responsibilities
- You’ll decompose problems into specs precise enough that an agent can implement them directly and concretely, and you’ll own everything you merge, because agent output is your output
- You’ll review rigorously. The bar is production software for a regulated federal financial system: test-driven development, human review on every merge, and a rigorous CI scans
- You’ll ship constantly. Small reviewable changes, an always-green main branch, an always-on beta environment stakeholders can touch
- You get to play with all the latest cool tech as part of your job
- You’ll own the heart of the rebuild: the domain model and services that replace decades of accumulated business logic
- Domain services in TypeScript/Node behind a REST API: case lifecycle state machines, document generation, pricing and payment-schedule calculation engines, workflow and milestone logic
- Business-rule archaeology. The legacy system’s rules live smeared across converted Java, PL/SQL packages, and database triggers. You’ll help extract them into an evidence-cited knowledge base, then reimplement them with tests that prove parity, including golden-master harnesses that replay legacy calculations and diff results to the penny
- Financial-grade correctness. Append-only audit trails, segregation-of-duties enforcement, reproducible calculations, and interface controls. This system faces federal financial audit standards, and we build that in rather than bolting it on
- External interfaces. Rebuilding file-based and API integrations with a dozen partner systems (logistics, accounting/ERP, training management), contract-first, with emulators before live connections
Skills
- US citizenship and eligibility for a US SECRET clearance
- 7+ years building and operating production web systems
- Mentors the mid deliberately
- Strong track record building production web systems, with demonstrable depth in server-side and domain-model work
- Hands-on experience with agentic AI development tools (Codex and/or Claude Code, or equivalent) on real codebases
- Fluency across the ecosystem: cloud infrastructure, CI/CD, and security fundamentals
- Travel no more than once per quarter
- Ability to read PL/SQL and legacy Java (you'll be doing archaeology, not just greenfield work)
- Experience with financial calculation engines, audit- or compliance-sensitive systems, or complex state machines
- Prior work in a regulated or government environment (FedRAMP, RMF, IL-anything)
- REST API design at scale
- Oracle-to-Postgres migration scars
Benefits
- Eligible employees may participate in Redhorse's comprehensive benefits programs
- May be eligible for performance-based or other incentive compensation, where applicable
