About This Job

Valar Atomics' mission is to make the world’s energy by mass-manufacturing and operating nuclear reactors. We are looking for people interested in helping us engineer the next Atomic Age.

We are seeking a

Generalist Software Engineer

to design, build, and maintain full-stack software applications and embedded/controls applications. You will work at the intersection of traditional software development with cloud platforms and on-premise servers as well as safety-critical control software for operating nuclear energy production and chemical process plants.

What You’ll Do

•

Develop Controls Software Write, test, and optimize real-time control applications in C/C++, Rust, and Python for reactor instrumentation and chemical plant control loops.

•

Integrate Enterprise-Scale Systems Build robust APIs and messaging layers (MQTT, OPC-UA, publisher-subscriber frameworks, REST/gRPC) to connect PLCs, historians, MES/ERP/Risk & Project planning platforms, and data lakes.

•

Architect & Deploy Cloud Infrastructure Design, implement, and operate IaaS/PaaS solutions across AWS, GCP, Azure, and DigitalOcean—using Terraform, and CI/CD pipelines.

•

Ensure Safety & Compliance Implement security-by-design, formal verification, and rigorous testing (HIL/SIL) to satisfy NRC, IEC 61508 (SIL 2-3), and other regulatory requirements.

•

Monitor & Optimize Develop dashboards (Grafana, Prometheus) and alerting for system health, performance metrics, and anomaly detection; on-call alerting/notification systems

•

Collaborate Across Teams Work closely with electrical and mechanical engineers, process safety experts, and operations teams to translate scientific and regulatory requirements into reliable safety-aware software.

Required Qualifications

•

1-3 years of professional experience building production-grade systems spanning both cloud platforms and embedded/control environments.

•

Strong proficiency in Python and one or more compiled languages (C/C++, Rust, Go).

•

Hands-on experience with DevOps and major cloud platforms (AWS, GCP, Azure, Digital Ocean, etc.)

•

Experience working with real-time operating systems, PLC programming, and embedded development on custom hardware.

Preferred Qualifications

•

B.S. in Computer Science, Computer Engineering, Electrical Engineering, or related field; or equivalent working experience.

•

Nice to have, but not necessary: Prior experience in the nuclear or chemical process industries.

•

Knowledge of physical layer communication protocols, serial communication protocols, UDP+TCP/IP and general networking infrastructure.

•

In-depth DevOps, cloud infrastructure, cross-compilation, and build tooling expertise; ability to fully reason about how to take any software you write from development and testing to deployment in production.

•

Knowledge of how code gets executed on the hardware on which one’s software is running.

Technical Stack

•

Languages & Frameworks: Python, C/C++, Rust, Go, frontend development

Cloud & Infra: AWS, GCP, Azure, DigitalOcean; Terraform (Infrastructure-as-code), CI/CD pipeline development, nix systems

•

Controls & Embedded: Bare-metal programming, RTOS, resource constrained software development, PLC programming

•

Communication: MQTT, OPC UA, REST/gRPC, TCP, UDP, IP, Ethernet, serial communication (I2C, SPI, USB), ModBus, HART

•

Data & Monitoring: Prometheus, Grafana, TimescaleDB and PostgreSQL (timeseries-optimized relational databases)

•

CI/CD & Testing: GitHub Actions, static analysis tools, fuzzing, HIL/SIL testing, debugging tooling, software instrumentation and logging
