Senior Software Development Engineer Jobs in Pasadena, CA

About the role:

The Sr. Software Development Engineer on the Duro Design team builds and ships product experiences that hardware engineers rely on every day. You'll work across our modern stack-from frontend interfaces to backend architecture-to deliver elegant, performant, and scalable solutions. This role partners closely with product, design, and engineering teammates in a fast-moving, highly autonomous environment.

We're looking for engineers who think end-to-end, embrace experimentation, and leverage modern AI-powered workflows to move with speed and precision. This is a hybrid role based in Los Angeles, CA (3 days per week in office).

A day in the life of our Sr. Software Development Engineer:

Feature Ownership: Decompose product requirements into well-structured tasks and own delivery from concept through production release.

Full Stack Development: Build across our stack (TypeScript, Node.js, NestJS, React, Apollo GraphQL, PostgreSQL, AWS) to deliver scalable, high-quality software.

Cross-Functional Collaboration: Partner with product and design teams to translate user needs into thoughtful, intuitive, and performant experiences.

End-to-End Thinking: Architect, implement, test, deploy, and measure features with a focus on long-term maintainability and system integrity.

Experimentation & Analytics: Instrument features using PostHog, run experiments, analyze real user data, and iterate based on measurable outcomes.

AI-Driven Engineering: Leverage modern AI development workflows to increase velocity, structure context effectively, and deliver production-ready systems.

Continuous Improvement: Identify opportunities to refine architecture, improve performance, and scale systems while maintaining engineering excellence.

Who We're Looking For

Required:

5-12 years of professional software engineering experience with a demonstrated track record of shipping production-grade products

Bachelor's degree in Computer Science or related field

Strong foundation in TypeScript and React

Experience working with design systems such as Ant Design, Material UI, or similar

Backend experience with Node.js, NestJS, and GraphQL

Experience working with PostgreSQL and ORMs such as TypeORM or Prisma

Strong architectural thinking and ability to design scalable systems

Excellent written and verbal communication skills

Comfort operating in autonomous, fast-paced environments

A product mindset with the ability to navigate the full feature lifecycle

Nice to Have:

Experience building PLM, PDM, or hardware/manufacturing industry software

Background with AWS infrastructure

Experience with Docker, Kubernetes, or Terraform

Familiarity with event-driven systems (NATS, Redis, Kafka)

Testing experience using Vitest, Jest, or Playwright

Experience working in AI-augmented development environments

How We Build

We don't hire coders. We hire engineers who shape software.

At Duro, AI is integrated into our engineering workflows. Engineers leverage AI-powered development environments to orchestrate tasks, structure context, and accelerate delivery while maintaining high standards of craftsmanship.

We value:

Architectural intuition - understanding systems before implementing them

Precision in communication - clear requirements produce strong outcomes

Pattern recognition - knowing when to abstract, reuse, or experiment

Product taste - recognizing quality and refining toward excellence

Intellectual curiosity - continuously improving how we build

We optimize for engineers who can take ambiguous requirements and transform them into measurable, high-impact product outcomes.
