What is a senior Python Flask developer?

Senior Python Flask Developers are experienced software engineers who specialize in building web applications using the Python programming language and the Flask web framework. They are responsible for designing, developing, and maintaining scalable backend systems, APIs, and web services. In addition to strong coding skills, they often lead projects, mentor junior developers, and ensure best practices in code quality, security, and performance. Their expertise allows them to solve complex technical challenges and contribute to the overall architecture and success of software projects.

What are the key skills and qualifications needed to thrive as a senior Python Flask developer, and why are they important?

To thrive as a Senior Python Flask Developer, you need advanced proficiency in Python, deep understanding of the Flask framework, and experience designing scalable backend architectures, typically supported by a degree in computer science or related field. Familiarity with RESTful API development, database management systems like PostgreSQL or MySQL, and version control tools such as Git is essential, and certifications in cloud platforms or web development can be beneficial. Strong problem-solving skills, clear communication, and the ability to mentor junior developers are standout soft skills for this role. These abilities ensure efficient delivery of robust, maintainable web applications and foster productive collaboration within development teams.

What are some common challenges faced by senior Python Flask developers when working on large-scale applications?

Senior Python Flask Developers often encounter challenges such as managing complex codebases, ensuring scalability, and maintaining performance as applications grow. Integrating Flask with other technologies (like databases, caching systems, or third-party APIs) can introduce architectural complexities. Additionally, balancing rapid development with writing maintainable, well-tested code is crucial. Collaboration with frontend developers, DevOps, and QA teams is frequent, requiring strong communication and problem-solving skills.

Who we are
With its A.I.-powered robotic technology platform, Symbotic is changing the way consumer goods move through the supply chain. Intelligent software orchestrates advanced robots in a high-density, end-to-end system - reinventing warehouse automation for increased efficiency, speed and flexibility.
What we need
We are looking for a Senior Functional Safety Software Engineer to join our Functional Safety Software team within our Software Engineering organization. Your job will be to design, develop, and maintain safety-critical software applications that support advanced warehouse automation systems. You will work across embedded software, real-time systems, hardware interfaces, and functional safety disciplines to help ensure reliable and compliant operation of complex robotic platforms.
This is a hands-on engineering role focused on modern C++ development in QNX and POSIX-based environments. You will contribute to software architecture, hardware integration, test infrastructure, and functional safety activities while partnering closely with systems engineering, hardware, and cross-functional development teams.
What we do
The Functional Safety Software team is part of the Software Engineering organization, which is responsible for building the intelligent software platforms that power Symbotic's advanced automation systems. The team develops safety-critical software applications that coordinate and enforce the safe operation of robotics, automation hardware, and warehouse control systems across large-scale deployments.
Our development culture emphasizes thoughtful engineering, maintainable systems, technical rigor, and collaborative problem solving. We value engineers who take ownership, communicate clearly, and contribute to improving both the software and the development processes around it.
What you'll do
  • Design and implement safety-relevant software components in modern C++17 running on QNX and POSIX-based systems.

  • Develop software services that interface directly with hardware peripherals, low-level communication protocols, and vendor SDKs.

  • Build and maintain Python-based hardware-in-the-loop (HIL) test automation infrastructure.

  • Participate in functional safety activities including hazard analysis, DFMEA, FMEDA, fault tree analysis, and safety reviews.

  • Collaborate with systems engineers, hardware engineers, project managers, and cross-functional development teams to achieve system safety goals.

  • Improve build systems, CI pipelines, developer tooling, and software test infrastructure used across the engineering organization.

  • Support internal audits, third-party safety assessments, and functional safety compliance efforts throughout the product lifecycle.

  • Travel up to 25% as needed to support integration, testing, and cross-functional collaboration.

What you'll need
  • Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or related engineering discipline; Master's degree preferred.

  • Minimum of 5 years of experience developing systems-level or embedded software in complex technical environments.

  • Strong experience with C++, C, Rust, Go, or similar systems programming languages, with interest in modern C++ development.

  • Strong understanding of POSIX userspace concepts including threads, sockets, signals, IPC, and shared memory.

  • Experience working close to hardware, including interpreting datasheets, register maps, and hardware interface documentation.

  • Professional experience developing Python tooling or automation infrastructure, particularly for testing or integration workflows.

  • Familiarity with software development best practices including version control, code reviews, CI/CD, documentation, and maintainable software architecture.

  • Strong written and verbal communication skills with the ability to work effectively across matrixed engineering organizations.

Preferred qualifications
  • Experience with QNX or other real-time operating systems (RTOS).

  • Exposure to functional safety standards such as IEC 61508.

  • TÜV Functional Safety Engineer (FSE) certification.

  • Experience with hardware-in-the-loop (HIL) testing and automation.

  • Experience integrating vendor SDKs or working with binary communication protocols.

  • Contributions to open-source software projects or experience working in open-core development environments.

Our environment
  • Up to 25% of travel may be required. Employees must have a valid driver's license and the ability to drive and/or fly to client and other customer locations.

  • The employee is responsible for owning a credit card and managing expenses personally to be reimbursed on a bi-weekly basis.
