SenseOn is looking for a Security 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.

We are deliberately open to candidates earlier in their careers who have learned to operate at a senior level by leveraging AI tooling effectively. If you can ship production-quality work because you know how to wield Claude, Cursor, and the modern AI toolchain with judgement and rigour, we want to talk to you. What matters is the outcome, not the years on your CV.

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.

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. You will write and tune detection rules in SIEMs. You will debug customer environments. And you will 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.

What We Are Looking For

AI fluency as a core engineering skill. You treat AI tooling as a force multiplier, not a crutch. You know when to let an agent run, when to hand-write the code, and when to throw the output away. You can describe how you have used Claude Code, Cursor, or similar to ship something real, and you can explain what the AI got wrong as confidently as what it got right.

Curiosity that closes gaps fast. You may not have deployed a SIEM in production yet, but you can stand up a lab, ingest logs, write a detection, and have a conversation about it by the end of the week. You learn by building.

Engineering judgement. You can read someone else's code, including code an LLM wrote, and tell whether it is fit for production. You care about edge cases, error handling, and what happens when the customer's environment is not what the documentation said it would be.

Customer instinct. You can explain technical concepts without condescension, and you understand that the goal is the customer's outcome, not your own cleverness.

Customer Deployment and Technical Success

• Lead end-to-end SenseOn platform deployments and complex log ingestion rollouts without customer disruption.
• Conduct architectural reviews to define deployment strategies and identify integration opportunities.
• Own the post-sale technical relationship into steady-state operations, delivering against technical success criteria tied to quantifiable security outcomes.
• Available for international travel if required.

Renewal Support and Customer Value Quantification

• Provide the technical evidence base and build business cases for renewals and expansions, translating platform telemetry and incident response data into clear customer outcomes.
• Proactively health-check environments, close technical gaps, and resolve visibility issues ahead of renewal conversations.
• Collaborate with Sales Engineering to ensure continuity from pre-sale technical validation through to post-sale deployment.

Software Development and Integration Engineering

• Write production-quality software to build and maintain integrations across third-party security tools, SIEMs, identity platforms, and AWS, Azure, and GCP environments.
• Use AI tooling thoughtfully to accelerate integration development, while owning the correctness, security, and maintainability of the code that ships.
• Contribute reusable connectors to the SenseOn integration library and create custom automation to optimise security operations workflows.
• Work confidently across backend languages (Python preferred; Go, JavaScript, and Bash valued) utilising RESTful APIs, webhooks, and data pipeline patterns.

Detection Engineering and SIEM Development

• Write, tune, and maintain high-fidelity, low-noise SIEM detection rules by translating threat intelligence and attacker behaviour.
• Map coverage to the MITRE ATT&CK framework to address visibility gaps, and develop new detection logic with Security Operations.
• Iterate on rules post-deployment to reduce false positives, and provide expert guidance to customers regarding their detection strategy and risk posture.

Customer Success and Relationship Management

• Develop deep relationships with customer security leadership, acting as a trusted adviser across their security architecture.
• Proactively mitigate adoption risks, resolve deployment blockers, and conduct structured onboarding from platform fundamentals to advanced threat hunting.
• Monitor deployed environment health, address technical drift, and translate field experience into actionable product feedback internally.

Pre-Sales and Proof of Value Support

• Partner with Sales Engineering on Proof of Value (PoV) engagements, providing technical credibility to differentiate SenseOn.
• Contribute to bespoke technical demonstrations, architecture proposals, and solution designs for complex prospects transitioning from legacy platforms or traditional SIEM solutions.

Product and Analytics Feedback

• Act as a direct conduit between the field and product teams, raising well-evidenced bugs, feature requests, and detection improvements.
• Participate in User Acceptance Testing (UAT) for new platform releases to provide field-informed quality assurance.
• Identify cross-environment patterns to highlight new detection opportunities or platform capability gaps for the analytics backlog.

How to Stand Out

You do not need to tick every box. If you can show us:

• A side project, a homelab, a GitHub repo, or something you built with AI tooling that you are proud of.
• A clear story about a technical problem you took from confused to solved, and what role AI played in getting you there.
• Evidence that you can hold a conversation with a customer without hiding behind jargon.

...we want to hear from you.

What We Offer

• Competitive salary commensurate with experience
• Unlimited holiday allowance
• Hybrid working model with flexibility around customer commitments
• Bi-annual career progression review
• Personal learning and development budget
• MacBook and all necessary tooling provided
• Enhanced pension scheme
• Private healthcare through Vitality, with rewards and discounts
