- At Sophos, we believe in the power of diverse perspectives to fuel innovation. Research shows that candidates sometimes hesitate to apply if they don't check every box in a job description. We challenge that notion. Your unique experiences and skills might be exactly what we need to enhance our team. Don't let a checklist hold you back – we encourage you to apply
Desirable
- Experience integrating and deploying Generative AI or LLM-powered solutions
- Understanding of AI agent architectures, retrieval-augmented generation (RAG), and conversational AI systems
- Exposure to cybersecurity products (XDR, MDR, SIEM, SOAR) or adjacent security technologies
- A passion for learning and experimenting with emerging AI technologies, and translating them into impactful customer-facing features
What the job involves
- As a member of the Sophos Agentic AI team, the Senior Software Engineer II plays a key role in shaping and delivering AI-powered cybersecurity solutions. This role works closely with engineers, architects, product management, and cross-functional stakeholders to drive the team’s vision at scale
- The Senior Software Engineer II contributes as a hands-on developer while also providing broader technical leadership — setting direction for architecture and design, mentoring peers, and influencing multiple projects or services
- An ideal candidate will have a proven track record of building complex, scalable systems and a deep interest in Generative AI and its applications in cybersecurity. Experience with AI agents, or applied LLMs is highly valued, along with the ability to anticipate challenges, drive technical strategy, and solve real-world security problems using cutting-edge technology
- 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
- Provide technical mentorship and guidance to less-experienced engineers, helping them grow their skills and deliver high-quality code
- Influence architecture and design decisions across multiple services or projects, ensuring scalability, reliability, and alignment with long-term product strategy
- 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
Our take
Due to the fast-evolving nature of cybercrime, companies can struggle to keep their security up-to-date and resilient. Sophos provides managed cybersecurity services to identify and resolve cyberthreats within all sizes of organisations, combining cutting edge cybersecurity tech with expert support teams.
Leveraging AI and machine learning, Sophos' system automates the detection and blocking of over 99% of threats, meaning its analysts only have to hunt down and stop the most sophisticated attackers. As well as its Managed Detection and Response (MDR) product - which, serving over 15,000 customers, is the most-used on the market - the company also delivers Incident Response Services for those experiencing an active threat.
Sophos is not a new player in the cybersecurity space, but has demonstrated its dedication to innovation with continued product launches, updates, and acquisitions such as that of BAE spinout SOC.OS that have kept its tech at the front of the market. Alongside many of its peers, the effects of the economic climate have caused Sophos to cut staff as it focusses on achieving “the optimal balance of growth and profitability", but this recent hiccup does not take away from its position as a market leader continuously leading adaption in the space.
