Senior Python Engineer - Remote Eligible

Senior Python Engineer

As a member of the Sophos Agentic AI team, the Senior Software Engineer plays a critical role in designing and building AI-powered cybersecurity solutions. This role works closely with software engineers, architects, product management, and cross-functional stakeholders to bring the team's vision to life. The Senior Software Engineer not only contributes as a hands-on developer but also provides technical leadership—participating in architecture decisions and owning the design and delivery of key product features.

An ideal candidate will have a strong background in developing complex, scalable systems and a keen interest in Generative AI and its applications in cybersecurity. Experience with machine learning, AI agents, or applied LLMs is highly valued, along with a passion for solving real-world security challenges using cutting-edge technology.

What You Will Do

• Collaborate with engineering leadership, architects, product management, and cross-functional teams to define technical direction and feature priorities.
• Design and implement scalable, cloud-native microservices and REST APIs using Python, FastAPI, and Celery.
• Build AI-powered applications as well as the platforms and services that enable their development, deployment, and operation.
• Integrate and optimize data systems including Postgres, Redis, and Elasticsearch to support high-performance AI and cybersecurity workloads.
• Partner effectively with Product Management, DevOps, QA, and fellow developers to deliver solutions that meet both technical excellence and customer needs.
• Take end-to-end ownership of major features or projects from design through deployment and monitoring, working with a high degree of autonomy.
• Stay current with advances in Generative AI, cloud technologies, and cybersecurity, and bring forward ideas to keep the platform at the cutting edge.
• Work with Kubernetes, CI/CD pipelines, event-driven systems, and large-scale data processing to deliver robust, reliable services.

What You Will Bring

• BS in Computer Science or equivalent experience.
• Minimum of 5 years of professional software engineering.
• Minimum of 2 years recent hands-on Python development, delivering production services.
• Proficiency with at least one Python web framework (FastAPI, Flask, Django).
• Practical experience building and operating cloud-native applications on AWS, with working knowledge of containerization/orchestration (Docker, Kubernetes/EKS).
• Strong background in SQL databases (Postgres preferred); familiarity with Redis and Elasticsearch a plus.
• Comfortable working in Linux/Unix environments and modern development workflows.
• Demonstrated ability to design, implement, and own features end-to-end, with accountability for quality and maintainability.
• Strong problem-solving and debugging skills in distributed systems.
• Effective communicator and collaborator across engineering, product, and research teams.
• Familiarity with Agile/Scrum methodologies and iterative software delivery.
• Exposure to Generative AI platforms (AWS Bedrock, Azure OpenAI) or AI-assisted development tools (GitHub Copilot, Cursor, Windsurf).
• Interest in AI agent architectures, RAG, or conversational AI systems.
• Background in cybersecurity products (XDR, MDR, SIEM, SOAR) or adjacent technologies.
• Curiosity and passion for emerging AI technologies, with a track record of experimenting and translating them into impactful solutions.
