Job description

Our Mission

America’s defense industrial base runs on infrastructure built in the 1980s. Distributors and manufacturers managing our supply chain still manually stitch together email threads, supplier quotes, PDFs, government solicitations, and archaic ERP exports to manage billions of dollars passing through our supply chain in component level assemblies.

SalesPatriot changes that.

We're building the AI-native command center for U.S. defense logistics, eliminating the manual bottlenecks slowing down critical national security workflows. From F-35 bearings to Blackhawk rotor hubs, we’re helping distributors and manufactures quote faster, win more, and deliver the parts that keep NATO safe.

Quick Facts

• YC W25 company. Top 5% growth in batch
• Raised $6M+ seed, on a hyper-growth trajectory
• Backed by YC, SV Angel, Pear VC, and CRV
• We work 12–15 hour days because we’re obsessed with the mission

Full Stack Engineer

If you don’t know TypeScript and at least one JS-based frontend framework, don’t apply.

SalesPatriot is seeking a Full Stack Engineer to join its core platform engineering team. This role will contribute directly to the development, scalability, and reliability of SalesPatriot’s mission‑critical software platform supporting defense and supply‑chain operations.

The Full Stack Engineer will work closely with engineering leadership, founders, and customer‑facing deployment teams to design, build, and maintain robust systems that integrate with complex legacy environments and support high‑value, high‑impact workflows. Your code will be the backbone of the defense and supply chain infrastructure for the decades to come. From integrating with ancient government interfaces to architecting hyper‑dynamic workflows - no two days will be the same.

Key Responsibilities:

• Design, develop, and maintain full-stack application functionality, including:
  • Frontend user interfaces
  • Backend services and APIs
  • Database schemas and data models
• Contribute to the core platform code, building frontend components, backend functionality, and database architecture
• Implement integrations with external systems, including legacy government and enterprise platforms
• Collaborate with forward‑deployed deployment teams to translate customer requirements into production‑ready features which drive millions of dollars in revenue for our clients
• Ensure code quality through adherence to best practices, testing, documentation, and code reviews
• Support onboarding and technical mentorship of new engineering team members
• Manage timelines - if you say that a massive ERP ingestor will be built out in two weeks, millions of dollars will be on the line based on your timely delivery
• Train and onboard new team members
• Trial by fire: you will be onboarded during an on‑site implementation. Expect late nights and pressure from the customer - everyone, including the platform team, needs to experience the forward deployed hell.

What is success in this role?

• You ship code that is useful, maintainable, and clean.
• You communicate clearly with the founders, Deployment Strategists and Senior Software Engineers. That means:
  • Articulating ideas understandably and convincingly
  • Setting reliable deadlines and meeting them
  • Voicing concerns and justifying your stance
• You set the standard for yourself and others for customer‑centric engineering excellence. That means:
  • Code is a means to an end - you program to deliver value to the customer
  • You understand the weight of your contributions, and can be trusted to own them end‑to‑end
  • You mercilessly hunt down bad practices that will be detrimental long‑term, while understanding that sometimes, compromises need to be made.

Required Qualifications:

• Experience in shipping projects and products. Be ready to show us at least one full‑stack project (GitHub repo / web app / Loom demo video), or don’t contact us at all.
• Proficiency in TypeScript, JavaScript, and at least one frontend library (React, Svelte, Next etc)
• Knowledge of SQL databases, preferably Postgres
• Strong understanding of software engineering best practices, including version control, testing, and documentation
• Ability to work effectively in fast‑paced, high‑accountability environments
• Low ego, curiosity, and intellectual honesty – let’s face it: you’ll be constantly torn between the pursuit of engineering excellence and the urgency of deadlines . The only way this works is if you focus on outcomes, not “being right
