Job description

Senior Forward Deployed Software Engineer

New York, United States

About us

PhysicsX is a deep‑tech company rooted in numerical physics and Formula One, dedicated to accelerating hardware innovation at the speed of software.

We are building an AI‑driven simulation software stack for engineering and manufacturing across advanced industries. By enabling high‑fidelity, multi‑physics simulation through AI inference across the entire engineering lifecycle, PhysicsX unlocks new levels of optimization and automation in design, manufacturing, and operations.

The Role

Your primary responsibility is to help customers solve their most important problems by building and deploying applications that utilize the power of our physics AI models. As a Senior Forward Deployed Software Engineer, you will work directly with customers, data scientists, and machine learning engineers to develop applications that change the way advanced engineering is done.

You will also travel to customer sites in North America, Europe, Asia, and Oceania for an average of 3‑4 weeks per quarter to collaborate closely with customers on‑site.

People We’re Looking For

Technical ability

You have a track record of solving hard problems and a solid foundation in software engineering, API design, and deploying applications to production. A background in Mechanical Engineering or similar disciplines is a plus.

Proactivity & high ownership

You take ownership of impact for our customers, drive end‑to‑end solutions, and acquire new skills quickly to solve novel problems.

Solution‑focused

You are customer‑obsessed and work alongside customers to understand their problems and build applications that transform their engineering processes.

What a day might look like

Collaborate with cross‑functional teams – work with data scientists, machine learning engineers, designers, and front‑end engineers to deliver physics models that maximize value to customers.

E2E application design – shape tools for customers, prototype low‑lift ideas, ship them directly, and iterate rapidly with user feedback.

Backend development – build and maintain RESTful APIs (FastAPI) and microservices in Python, deploy these applications to the cloud using Helm, Kubernetes, Terraform, and AWS/Azure.

PhysicsX development – distill complex solutions into core platform components, pitch and execute feature development, and influence the direction of PhysicsX.

What we offer

• Build what actually matters – shape an AI‑native engineering company at a formative stage, tackling real‑world impact.
• Learn alongside exceptional people – collaborate with a high‑caliber, diverse team of engineers, scientists, and operators.
• Influence over hierarchy – operate with a flat structure where good ideas win, regardless of origin.
• Hybrid work model – blend time in our New York office with work‑from‑home days, providing flexibility and connection.
• Equity options – share meaningfully in the company you’re helping to build.
• 401(k) contribution – 5% employer match to support long‑term security.
• Free team lunch 1x/week – good food and community.
• Private health insurance – comprehensive coverage for you.
• Enhanced parental leave – 3 months full‑pay paternity and 6 months full‑pay maternity leave.
• 20 days of annual leave (+ public holidays) – rest and recharge.
• Personal development – dedicated support for learning, development, and growth.
• Gympass / Wellhub (subsidized) – support for physical and mental wellbeing.
• Flexible Spending Account (FSA) – pre‑tax dollars for eligible healthcare expenses.

Compensation

Salary range: $150,000 – $250,000, depending on experience. Seniority will be assessed during the interview process.
