The interview process at Medra is designed to be highly interactive, supportive, and holistic. The team aims to evaluate your technical capabilities while giving you a clear sense of what it is like to collaborate with their engineers on a daily basis.

The process generally moves through three primary phases:

First, you will participate in an introductory call, often with the Head of Robotics or a hiring manager. This conversation focuses on your background, your engineering interests, and your alignment with Medra's mission. It is also an opportunity for you to ask questions about the team's roadmap and technical stack.

Following a successful screen, you will move to a technical coding interview with a lead engineer. This round typically involves a practical programming challenge, such as building a custom encryption/decryption protocol in any language you prefer, where the focus is on clean implementation and logical flow. Finally, you will complete an onsite loop that combines deeper technical deep dives, system design discussions, and behavioral interviews.

The visual timeline above outlines the standard progression of the Medra hiring loop. Candidates should use this sequence to pace their preparation, ensuring they transition from fundamental coding practice in the early stages to system-level brainstorming and behavioral storytelling for the onsite. While the exact timeline can vary slightly depending on candidate availability, the structured progression remains consistent across software roles.

To excel in the Medra interview process, you must understand exactly what engineers are looking for during each technical interaction. The evaluation is structured around core competency areas that reflect the day-to-day realities of building robotics software.

Protocol Design and Data Management

Robotic systems rely on fast, secure, and reliable communication between diverse hardware and software modules. Interviewers will evaluate your ability to design protocols that can handle structured data efficiently.

Be ready to go over:

• Serialization & Deserialization – How to convert complex in-memory data structures into byte streams for transmission and vice versa.

As a Software Engineer at Medra, your daily work will span the entire software lifecycle, from initial system design to deployment and physical testing. You will write code that runs in production environments, directly interacting with robotic hardware.

Your primary responsibilities will include:

• Designing, writing, and maintaining high-quality, reliable full-stack software to control, monitor, and test robotic automation systems.
• Developing robust communication protocols and APIs to connect cloud platforms, local edge computers, and microcontrollers.
• Collaborating closely with Mechanical Engineers and Systems Test Engineers to integrate software features with physical prototypes.
• Participating in regular code reviews, architectural brainstorming sessions, and system troubleshooting efforts.
• Building internal tooling, visualization dashboards, and automated testing suites to accelerate the team's development velocity.

To be competitive for a Software Engineer position at Medra, you should bring a strong foundation in modern software development practices along with a passion for physical automation. The team looks for versatile engineers who can adapt to a variety of technical challenges.

• Must-have skills – Proficiency in at least one major programming language (such as Python, C++, Go, or TypeScript/JavaScript). Strong understanding of data structures, algorithms, and system design principles. Experience building and consuming APIs, as well as working with relational or non-relational databases.
• Nice-to-have skills – Prior experience working with robotics middleware (such as ROS/ROS2), hardware-software integration, or low-level systems programming. Familiarity with cloud infrastructure (AWS/GCP), containerization (Docker), and real-time web communication protocols (WebSockets, WebRTC).
• Experience level – Typically requires a Bachelor's degree in Computer Science, Computer Engineering, or a related technical field, combined with professional software engineering experience. For leadership roles like Tech Lead Manager - Full Stack, a proven track record of leading technical projects and mentoring junior engineers is expected.

Q: What is the typical programming language expectation during the interview? A: Medra is highly language-agnostic during the coding phases. You are encouraged to use the programming language you are most comfortable with, whether that is Python, C++, Go, or JavaScript, as long as you can write clean, structured, and idiomatic code.

Q: How much hardware or robotics experience do I need? A: While prior experience with robotics, ROS, or hardware integration is a strong plus, it is not a strict requirement for all software roles. Strong software engineering fundamentals, systems-level intuition, and a genuine eagerness to learn about hardware are highly valued.

Q: What is the hybrid or remote work policy for this role? A: Because this role involves direct integration with physical robotic systems, regular onsite presence at the San Francisco, CA office is typically required. This allows close collaboration with the hardware and systems testing teams.

Q: How long does the entire interview process take? A: The process typically takes between two to four weeks from the initial introductory call to the final decision, depending on scheduling availability and the speed of candidate progression.

To maximize your chances of success during the Medra interview process, keep these practical, insider tips in mind:

• Over-communicate your thought process: Do not solve problems in silence. Talk through your assumptions, explain why you are choosing a specific data structure, and outline your approach before you begin writing code.
• Focus on edge cases early: When designing protocols or writing code, explicitly state the edge cases you are considering (e.g., network drops, null inputs, buffer overflows) and explain how your solution handles them.

• Treat the interviewer as a teammate: The onsite loop involves a lot of brainstorming. Approach these sessions as a collaborative work meeting rather than an interrogation. Show that you are easy to work with and receptive to feedback.

• Brush up on networking and systems basics: Even if you are applying for a full-stack or frontend-heavy role, having a basic understanding of how data travels over a network and how systems handle concurrency will serve you well.
