Embedded Firmware Engineer

Remote within the Philippines.

About the Role

We are seeking an experienced Embedded Firmware Engineer to support a seismograph hardware company with products deployed globally in demanding field environments.

This role combines ownership of a mature production firmware platform with development support for a next-generation device currently in beta. The firmware is written in bare-metal C and runs on a 32-bit AVR32 microcontroller. There is no RTOS, Linux layer, or hardware abstraction framework handling the complexity for you.

You will work directly with physical hardware, investigate field-reported issues, analyze binary event records, and make changes to firmware running on mission-critical instrumentation.

The client has a highly knowledgeable technical stakeholder who understands the system deeply and will support onboarding and product knowledge transfer.

Work Schedule: Mondays to Fridays; Flexishift with a 4-hour overlap with the client

Key Responsibilities

• Own firmware maintenance for a production product line
• Investigate and resolve field-reported firmware issues
• Develop and test firmware enhancements and minor features
• Support firmware development on a newer custom-hardware platform in beta
• Analyze anomalous seismograph readings and trace behavior through firmware execution paths
• Work directly with hardware to validate changes and troubleshoot issues
• Communicate findings, recommendations, and implementation details to the client’s technical lead
• Participate in an Agile delivery process using Azure DevOps and two-week sprint cycles

Requirements

Ideal candidates SHOULD have the following qualifications:

Bare-Metal Embedded Development

• Proven experience shipping firmware written in C on microcontrollers without an operating system
• Comfortable working with startup code, linker scripts, memory maps, and low-level initialization

Real-Time & Interrupt-Driven Systems

• Professional experience writing and debugging Interrupt Service Routines (ISRs)
• Strong understanding of interrupt/main-context communication and timing-sensitive behavior

Peripheral Driver Development

• Experience implementing SPI, I2C, and UART drivers at the register level
• Ability to configure peripherals directly from vendor reference manuals and datasheets

Power Optimization

• Experience profiling and reducing power consumption on battery-powered embedded devices
• Understanding of sleep modes, peripheral power states, and wake-up latency tradeoffs

Hardware-Centric Debugging

• Experience developing on platforms without simulators or manufacturer emulators
• Proven methodology for validating and troubleshooting firmware on physical hardware

Datasheet-Driven Engineering

• Comfortable navigating large vendor reference manuals and configuring peripherals from scratch

Preferred Qualifications

• Experience with 32-bit RISC microcontrollers (ARM Cortex-M, STM32, NXP LPC, i.MX RT, SAM, PIC32, etc.)
• Familiarity with Atmel/Microchip ecosystems
• Experience with ASF, avr-gcc, or Atmel/Microchip Studio
• Experience inheriting and maintaining legacy embedded codebases
• Experience shipping firmware for field-deployed products where reliability is critical

Nice to Have

• Direct AVR32 (UC3/AP7) experience
• USB peripheral driver development experience
• Background in industrial, scientific, instrumentation, or data acquisition systems
