About The Position

Dexory is hiring a Lead Fleet Performance Engineer to build the function responsible for understanding fleet health, anticipating what the fleet will do next, and prioritizing what needs to be fixed. The role combines hands-on analysis of robot data and systems with leadership: hiring, coaching, and growing a team while working closely with Service, Engineering, Software, and V&V.

The successful candidate will establish fleet-health measures and reporting, use logs and telemetry to identify and assess emerging issues, and ensure diagnostic data is captured well enough to investigate significant incidents. They will develop fleet alerts and pre-failure detection, manage configuration baselines and drift, improve fleet data quality and hardware-health tracking, and use fleet data to set preventive-maintenance intervals. In release-candidate analysis, they will provide evidence and recommendations to V&V, which owns the release decision. They will also maintain a register of the most significant failure modes and drive high-impact fixes with Engineering.

In the first twelve months, the intended outcomes include trustworthy baseline metrics, useful alerts with a low false-positive rate, adequate diagnostic data capture, permanent elimination of at least two recurring failure modes, visible fleet configuration with detectable drift, and one or two reliability engineers hired and productive.

Dexory describes its culture through four operating principles: Performance, Impact, Commitment, and One team. The company offers equal employment opportunities and prohibits discrimination and harassment in accordance with applicable local laws.

Requirements

• Substantial engineering experience in reliability, SRE, platform operations, robotics operations, or a strongly data-driven engineering role.
• Fluency with telemetry and observability, such as Grafana or similar tools, time-series data, SQL, and Python.
• Analytical judgment to separate signal from noise and distinguish an unusual robot from a failing one.
• Systems depth sufficient to work credibly with engineers, including Linux, logs, and distributed systems.
• Ability to argue a case from evidence and hold a position with engineering and hardware teams.
• Discipline to protect proactive work from reactive demands.
• Genuine interest in growing into a leadership role while continuing to build hands-on.

Nice To Haves

• Experience with ROS or another robotics stack.

Responsibilities

• Define and own fleet-health measurements, standards for healthy performance, and reporting.
• Investigate fleet-wide behavior using logs and telemetry; identify emerging warnings, determine likely causes such as release or configuration changes, quantify exposure and impact, and assess operational severity.
• Own fleet diagnostic-data capture, coordinating rosbag recording rules, log pipelines, and telemetry coverage with other teams.
• Own alert thresholds, alert quality, resolution, and escalation.
• Develop pre-failure detection for robot subsystems.
• Own fleet configuration management, including baselines, drift detection, change visibility, and making configuration more manageable.
• Own fleet data quality and the hardware-health foundation, including component-level tracking and a monthly fleet-health report to Service and Engineering.
• Set preventive-maintenance intervals using fleet data.
• Work with V&V on release-candidate analysis, interpret evidence from RC robots, identify regressions before wide rollout, and recommend whether to proceed, hold, or roll back; V&V owns the release decision.
• Build a top-failure-modes register and drive the highest-impact issues to resolution with Engineering.
• Report fleet health to Service, Engineering, and Software.
• Hire, coach, and grow the team while remaining hands-on with data and robots.

Benefits

• Private healthcare via Bupa with a 24/7 medical helpline.
• Life insurance.
• Income protection.
• Pension with 4%+ employee contribution, an option to opt into salary exchange, and 5% employer contribution.
• Employee Assistance Programme providing mental wellbeing, financial, and legal advice and support.
• 25 holidays per year.
• Full meals onsite in Wallingford.
• Team events on and offsite.
• Office snacks.
