# Christopher Arjune > Developing the Next Generation of Security! | Device Security Software Engineer @ Verkada Location: San Mateo, California, United States Profile: https://flows.cv/christopherarjune Always interested to work on a new project, with a skillset ranging from the IC level all the way up to RTOSes, and encompassing any analog or digital work you can find in between. Most commonly, I find myself working on firmware, but I'm at my best when I have the opportunity to explore all HW and SW aspects of an embedded system. If you just want someone to myopically focus on a particular code snippet, look elsewhere. ## Work Experience ### Software Engineer | Device Security @ Verkada Jan 2024 – Present | San Mateo, California, United States ### Embedded Software Engineering Intern @ Skydio Jan 2023 – Jan 2023 | San Mateo, California, United States As an Embedded Software Engineering Intern at Skydio, I had the novel opportunity to work at the forefront of a product release cycle by contributing to the development of the new Skydio X10 enterprise drone. My primary focus was the design and implementation of the Factory Reset feature, a project which entailed a multitude of modifications to the drone's C and Python code. The core design of the feature centered around reliable, lightweight communication between the Linux userspace and boot-time C code, in order to safely wipe the filesystem of temporary changes as efficiently as possible. The feature was exposed to developers through a simple debug CLI, while the user-facing implementation required modifications to the Python code that interfaced the mobile app with the onboard NVidia and Qualcomm SoCs, initiating and synchronizing the shared reset behaviour of the processors, and reporting status updates back to the user's controller. The end result was a robust and intuitive method for users and developers alike to restore their drones to a clean, factory-like state. Apart from working on the Factory Reset feature, I also had the opportunity to work on patching various bugs for release, improving the robustness of the X10's OTA update system, debugging various drone issues for other developers and testers in the office, and rewriting some of the charging driver code present on the STM32 microcontroller used in the Skydio Dock to implement I²C using purely asynchronous operations. ### Electronics Engineering Intern @ Samsung Research America (SRA) Jan 2023 – Jan 2023 | Mountain View, California, United States During my co-op term at Samsung Research America, I worked on a variety of multi-disciplinary projects as part of the Think Tank Team, with the bulk of my work revolving around the development and/or improvement of HW/SW prototypes. Some examples include flattening the frequency response and improving the SNR of an audio amplifier circuit, implementing real-time, context-based classification and reduction of sensor noise in C, and developing a compact, low-power rev1 prototype circuit for a potential new project idea. Along the way, I was also able to broaden my personal range of experience and tools by getting familiar with using digital oscilloscopes (Picoscope, Digilent Analog Discovery 2) for ease of electrical signal monitoring and recording, as well as using Jupyter Notebook for improved data visualization, manipulation, and algorithm prototyping. ### Firmware Development Intern @ onsemi Jan 2022 – Jan 2022 | Waterloo, Ontario, Canada During my co-op term at onsemi, my main responsibility was the development and integration of GPIO-related libraries for the new, ARM Cortex-M33 based RSL20 platform. Specifically, I designed pushbutton and LED management libraries that were designed to be easy to integrate into our customers' existing hearing aid applications, while also providing a level of uniformity to our sample applications. The library design process involved determining project requirements and scope, figuring out how to integrate the SysTick and TIMER modules into the design in a flexible way, writing C code that was highly configurable and able to serve all possible customer needs, creating internal and customer-facing SDK documentation, developing self-testing applications to verify library behaviour, and integrating these libraries into our existing sample applications. These libraries will ultimately serve not only as an improvement to the uniformity and feature set of our existing sample code, but may also act as a template for similar designs on other projects in the future. I also worked on some tasks related to automated application testing, working to improve our test infrastructure for future developers, and using the Python BEHAVE framework to write automated tests for some sample applications. These automated tests are part of the test suite that is run on a regular basis by our Jenkins server, and are also used during SDK release cycles to verify behaviour for customers. ### Firmware Development Intern @ Ford Motor Company Jan 2021 – Jan 2021 | Ontario, Canada During my co-op term at Ford, my main focus was to continue a previous co-op student's investigation into using Vector's MICROSAR Runtime Measurement (RTM) module in order to provide performance metrics for system debugging. Throughout my investigation, I became intimately familiar with the RTM module, eventually figuring out how I could scrap the module and its significant overhead entirely, and create a much more lightweight implementation using timestamps from our 1us free-running timer and OS context-switch hooks in order to record the execution time of all OS tasks and ISRs. This implementation has since been used to evaluate the performance of various shared memory implementations, as well as to debug an OS error that was causing system crashes. I also assisted various testing teams by creating useful user console commands, such as a command to reset all Diagnostic Identifier values to default, and a command to toggle developer mode in a way that persists across system power cycles. ### Robot Controller Project Lead @ UW Mars Rover Robotics - Electrical Subteam Jan 2020 – Jan 2021 | Waterloo, Ontario, Canada As the lead of the robot controller PCB project, my role was to manage all research and design for the UWRT custom controller. This entailed organizing meetings to discuss research plans, reaching out to other robotics teams to learn more about their designs, researching the best control components, planning out control schemes, and finally, designing schematics and PCBs for the development and rev1 boards. ### Science Project Co-Lead @ UW Mars Rover Robotics - Electrical Subteam Jan 2019 – Jan 2020 | Waterloo, Ontario As a co-lead of the science PCB project, I worked on all aspects of the board design process. The rev1 schematic and PCB were designed in Altium, and then assembled using a mixture of through-hole and 0603/0805 SMD soldering. Boards were tested using a variable PSU, DMM, and oscilloscope, and firmware was written in C++ to perform initial GPIO testing, as well as to interface with an I²C sensor using MBED OS functions. Occasionally, I also assisted with design reviews, assembly, and FW bringup for PCBs from other projects. ### Product Development Engineering Intern @ Baanto Jan 2021 – Jan 2021 | Mississauga, Ontario, Canada During my second co-op term at Baanto, I focused on modifying their existing USB implementation on all their systems, which included creating a boot-compliant keyboard HID interface, minimizing memory usage, as well as fixing and verifying USB 2.0 compliance. I also assisted with various other tasks, such as investigating the feasibility of including STM32CubeMX in their product development workflow, debugging communication errors, as well as identifying and removing dead code. ### Product Development Engineering Intern @ Baanto Jan 2020 – Jan 2020 | Mississauga, Ontario, Canada During my first co-op term at Baanto, I mainly focused on starting the development of their Built-In-Test (BIT) functions. The BIT project deals with trying to detect and characterize hardware faults within the touchscreens during normal operation, so that the company implementing the screens can be more knowledgeable about what issues may be occurring with their system, as well as when it may be time for a replacement. I also occasionally assisted with other tasks which pertained to debugging, optimization, cleanup, documentation, etc. ### Robotics Leader @ Peel District School Board Jan 2018 – Jan 2018 | Ontario, Canada As part of the PDSB Camp SAIL summer camp, I worked as part of a team of Robotics Leaders who delivered daily robotics educational experiences to elementary school students. Throughout these experiences, we introduced the children to a variety of different beginner robotics kits, educated them on basic electrical properties, and encouraged critical thinking through both individual and team-based challenges. On multiple occasions, we also assisted with delivering workshops to the students' parents regarding the importance of STEM education in their children's lives, as well as introduced them to some of the technology being used in order to give them an understanding of how their children were being educated. ## Education ### Bachelor of Applied Science - BASc in Computer Engineering University of Waterloo ## Contact & Social - LinkedIn: https://linkedin.com/in/christopher-arjune --- Source: https://flows.cv/christopherarjune JSON Resume: https://flows.cv/christopherarjune/resume.json Last updated: 2026-04-11
