Full Job Description

Fieldpiece is hiring an Embedded Software Engineer to contribute to the design, development, and support of the embedded software that powers our connected instruments, wireless tools, probes, analyzers, and diagnostic systems. This role focuses on hands-on firmware development and close cross-functional collaboration. We are looking for an engineer who can work from product and technical requirements, contribute to embedded software design decisions, and help deliver product functionality from concept through production. You will collaborate closely with product management, electrical engineering, mechanical engineering, QA, and manufacturing teams to deliver reliable, high-quality products used by technicians worldwide.

Fieldpiece is a thriving team of innovators - committed to pushing boundaries and celebrating curiosity. We’ve been providing HVACR professionals with rugged, feature-rich tools like meters, manifolds, leak detectors, and more since 1990. Recognized as one of Southern California’s Best Places to Work (2023, 2024, 2025, & 2026), we provide a Hire-to-Retire philosophy, hybrid schedule, and a culture of curiosity – a place where you’ll have the support to innovate boldly, grow continuously, and make a tangible impact on an industry that powers everyday life.

The ideal candidate is:

Hands-on engineer who enjoys solving product and system-level problems.
Comfortable operating in a fast-paced product development environment with evolving requirements.
Passionate about building physical products that solve real customer problems.
Able to balance technical depth with practical decision-making and strong execution.
Collaborative engineer who communicates effectively across technical and non-technical teams.

This position is currently located in our Orange, CA office with an exciting move to a new office in Tustin, CA in mid-2028.

What You’ll Do

Develop and maintain embedded software and firmware for microcontroller-based products (ARM Cortex-M, ESP32, PIC, or similar platforms).
Design and implement software for connected handheld instruments, wireless systems, sensors, and mobile-integrated products.
Develop low-level drivers, communication stacks, middleware, and application-layer functionality.
Optimize software for performance, memory utilization, power efficiency, reliability, and maintainability.
Define software behavior, technical requirements, specifications, and test criteria based on customer and product needs.
Collaborate cross-functionally with hardware, product management, QA, manufacturing, and engineering teams throughout the product lifecycle.
Support board bring-up, system integration, debugging, root-cause analysis, validation testing, and production readiness activities.
Write clean, maintainable, and testable code while contributing to code reviews, development standards, and continuous process improvement.

Bachelor’s degree in computer engineering, Electrical Engineering, Computer Science, or related STEM field; advanced degree a plus.
3+ years of experience developing and maintaining embedded software and firmware for microcontroller-based systems.
Strong proficiency in C/C++ for embedded systems development.
Experience working from software requirements, system behavior definitions, and technical specifications for embedded products.
Experience with RTOS, embedded Linux, wireless communication protocols, BLE, UART, SPI, I2C, or similar technologies preferred.
Strong understanding of hardware/software integration and system-level debugging.
Experience supporting products through development, validation, and production in a cross-functional environment.
Ability to create clear documentation, technical requirements, and validation/test plans.
Passion for product quality, usability, and reliability in real-world applications.
Strong problem-solving, communication, and collaboration skills.
Experience supporting manufacturing and production environments preferred.
Prior experience working with offshore manufacturing partners or external vendors is beneficial but not a primary focus of the role.

At Fieldpiece, we believe great work deserves great rewards. We offer:

Matching 401k up to 4% with immediate vesting.
Excellent medical benefits including an HSA plan and monthly contributions.
Supplemental Term Life, Employee Assistance Programs (EAD), Disability, and more.
Hire to Retire philosophy that includes personal career development plans.
Onsite music program with lessons from guitar, piano and voice coaches.
And more!

Our values drive everything we do and our culture.

We are a TRIBE.

Our collective growth starts with individual growth.

We are fully engaged and empowered, collaborating to achieve our common mission.

Our people are central in making Fieldpiece the best place we will work, ever.

We do the UPFRONT HOMEWORK.

We are prepared before coming together to move forward effectively.

We begin with the end in mind by understanding The Why upfront, visualizing, researching, and acting.

We address obstacles head-on with creativity, grit and tenacity, while having fun along the way.

We deliver the RIGHT STUFF.

We deliver innovative solutions by seeing the world through the eyes of our customers.

Our culture of purposeful critical thinking leads to greatness now, rather than perfection never.

We earn TRUST.

We prove our credibility, reliability, and genuine interest in others to build lasting relationships.

Our tribe, partners, end users, suppliers and channel partners can rely on us to listen, act with integrity, and deliver quality.

We are LEAN.

We never stop searching for a better way.

We get started, fail fast, and move forward.

Our actions deliver valuable results.

We leave our EGO at the door.

We are unconcerned to be judged by the questions we ask.

With humility, we value and pursue ideas and feedback from everyone.

Our personal success is derived from the tribe’s success.

The California base annual salary range for this role is currently $140,000-180,000 plus 10% bonus. Pay scales are determined by role, level, location, and alignment with market data. Individual pay is determined through interviews and an assessment of several factors that that are unique to each candidate, including but not limited to, job-related skills, relevant education and experience, certifications, abilities of the candidate and pay relative to other team members. We can share more information about our bonus program and benefits during the hiring process.
