# Senior Software Engineer, Modeling & Simulation

> Code Metal · Boston, United States (Hybrid) · — · Posted 2025-05-08

**Workplace:** hybrid

## Description

Help redefine how the DoD makes multi-billion-dollar force-design decisions. In this role, you'll fuse physics-driven simulation, interactive computing, and verified AI code-generation to create next-generation wargaming platforms. We’re seeking an experienced software developer who can own key parts of a larger extensible, cloud-distributed simulation environment, and inspire a small, high-conviction team by leading from the front.

### What you’ll do

-   **Design & implement** a scalable, interactive physics simulation that runs seamlessly in cloud and on-prem clusters.
-   **Own core functionality** in modern C++ from multi-threaded performance tuning to continuous integration.
-   **Collaborate with product & AI teams** to embed verified, AI-generated algorithms directly into a developer SDK for extending the platform.
-   **Prototype quickly, iterate faster:** deliver usable capability to government end-users in weeks, not months.
-   **Set the engineering bar**—write clean code, document rigorously, and mentor teammates through code reviews and pair programming.

### Why Code Metal?

-   **Mission with impact:** your work shapes the digital battlefield models that influence real-world acquisition.
-   V**elocity:** small teams, rapid iteration cycles, and the mandate to ship.
-   **Ownership:** no passengers, everyone pushes code that hits production.

## Requirements

### Must-have credentials

-   Bachelor's degree (or equivalent experience) in applied math, scientific computing, physics, or a related field.
-   Proven expertise in **multi-threaded C++** for high-performance applications.
-   Hands-on experience with **large-scale, physics-based simulations.**
-   Active **Secret clearance** or eligibility to obtain one.

### Bonus points

-   Master’s (or equivalent experience) in applied math, scientific computing, physics, or similar.
-   GPU compute chops—OpenCL, CUDA, or both.
-   Prior work running physics simulations in **distributed cloud environments.**
-   **TS/SCI clearance.**

## Benefits

-   Health care plan with 100% premium coverage, including medical, dental, and vision.
-   401k with 5% matching.
-   Paid Time Off (Uncapped Vacation, plus Sick & Public Holidays).
-   Flexible hybrid work arrangement.
-   Relocation assistance for qualifying employees.
