Security Engineer, Field Operations

SenseOn is looking for a Forward Deployed Engineer to sit at the intersection of security engineering, software development, and customer success. This is one of the broadest and most impactful technical roles in the business; you will be the person who makes SenseOn work in the real world for real customers.

As a Forward Deployed Engineer, you will embed directly with customers to deploy and configure the SenseOn platform, develop custom integrations, and ensure that every customer derives measurable security value as quickly as possible. You will own the technical outcome, supporting technical sales and working on technical delivery to enable SenseOn to be effective. This is not a pre‑sales or demo role. You support both new business engagements and existing customer renewals, providing the technical depth to prove and quantify the value SenseOn delivers and ensuring that as deployments grow more complex with expanded log ingestion, customers always feel in safe hands.

You will report to the VP of Technology and work closely with the Security Operations, Customer Success, Sales Engineering, and Product teams.

Location: UK. Travel: Approx 25% to customer sites.

Experience: 3 to 6 years+

Requirements

• Essential 3-6 years of experience in a technical cybersecurity role, ideally spanning Security Operations and an engineering or customer-facing function.
• Demonstrable software development capability; you must be able to write, review, and deploy code in a production context. Python is strongly preferred.
• Proven ability to write and tune detection rules in one or more SIEM platforms (e.g. Splunk, Microsoft Sentinel, Elastic, QRadar). You are comfortable translating threat scenarios into detection logic and iterating on rule quality based on operational feedback.
• Hands-on experience building and troubleshooting integrations with cloud platforms (AWS, Azure, or GCP), REST APIs, and common security tooling including SIEMs, EDRs, XDRs, and NDRs.
• Strong understanding of networking fundamentals, operating systems (Windows and Linux), and identity and access management concepts.
• Experience deploying or operating software in containerised environments (Docker, Kubernetes).
• Excellent written and verbal communication skills, with the ability to engage credibly with both technical engineers and non-technical stakeholders up to C-level.
• Based in the United Kingdom with the right to work in the UK.

Highly Desirable

• Prior experience in a Forward Deployed Engineer, Customer Success Engineer, or Technical Account Manager role at a security or SaaS company.
• Experience supporting customer renewal engagements from a technical perspective—building business cases, evidencing value, and closing coverage gaps ahead of renewal conversations.
• Familiarity with log ingestion at scale, including the operational and architectural challenges of onboarding diverse log sources across complex enterprise environments.
• Experience with CI/CD pipelines, Infrastructure-as-Code (Terraform, Ansible), and modern DevSecOps practices.
• Exposure to machine learning or AI‑driven security analytics platforms.
• Relevant industry certifications such as CISSP, AWS Solutions Architect, GCIH, or equivalent.
• Experience supporting or replacing incumbent security platforms (e.g. Darktrace, CrowdStrike, Splunk) within enterprise customer transitions.

The Role in Detail

You will own the full technical lifecycle of a customer deployment, from initial architecture review through to live production, ongoing integration development, and long‑term platform health. You will build cloud integrations, write and tune detection rules in SIEMs, debug customer environments, and ensure that every customer you touch becomes a SenseOn advocate. Your impact does not stop at deployment. As SenseOn's log ingestion capability grows and deployments become more complex and wide-ranging, you will work with the Customer Success team to build the technical business cases that win renewals and drive expansion, bringing the same engineering rigour to proving value as you do to deploying it.
