Lead Perfomance Engineer

At Dexory, we're developing advanced software powered by cutting-edge robots that are transforming the very face of global logistics. With infectious enthusiasm, our unique blend of disciplines work in harmony to produce results m hardware and manufacturing to software, AI and commercial, we're one team – one heart – that beats, learns and grows together.

We're only interested in the best ideas, no matter where they're from. We're doers. Game-changers.

Out-of-the-box thinkers who put merit before all else. A group of ambitious and disciplined individuals who are passionate about turning theory into rubber, metal and results.

Purpose
. Build the function that knows what the fleet is doing, what it will do next, and what to fix first.

Responsibilities

• Define and own fleet health: what we measure, what good looks like, and how it is reported.
• Investigate fleet-wide behaviour from logs and telemetry: spot a warning appearing on a handful of robots, work out which release or configuration change introduced it, quantify how many robots are exposed and how badly, and judge the real operational severity.
• Own the fleet's diagnostic data capture — work with other teams for rosbag recording rules, log pipelines, telemetry coverage. If a failure cannot be investigated because the data was not recorded, that is a reliability defect.
• Own alert thresholds, alert quality, resolution and escalation;
• Develop pre-failure detection of robot subsystems
• Own fleet configuration management: baselines, drift detection, change visibility, and driving the configuration itself towards something manageable rather than hand-tuned per robot.
• Own fleet data quality and the hardware health foundation: component-level tracking, and a monthly fleet health report to Service and Engineering.
• preventive maintenance intervals set from fleet data,
• Work alongside V&V on release candidate analysis: interpret what RC robots are showing, catch regressions before wide rollout, and recommend proceed, hold or roll back. V&V owns the release decision; you supply the evidence behind it.
• Build the top-failure-modes register and drive the highest-impact items to resolution with Engineering.
• Report fleet health to the interested teams (Service, Engineering, Software).
• Hire, coach and grow the team; stay hands-on with data and robots.
• Hire, coach and grow the team; stay hands-on with data and robots.

You'll need

• Substantial engineering experience in reliability, SRE, platform operations, robotics operations or a strongly data-driven engineering role.
• Fluency with telemetry and observability:
  Grafana or similar, time-series data, SQL, Python.
• The analytical judgement to separate signal from noise, and to tell the difference between a robot that is unusual and a robot that is failing.
• Enough systems depth to be credible with engineers:
  Linux, logs, distributed systems, and ideally ROS or another robotics stack.
• The ability to argue a case from evidence and hold a position with engineering and hardware teams.
• The discipline to protect proactive work from reactive pull.
• Genuine interest in growing into a leadership role - a strong engineer who wants to build and lead a team, not a manager who has stopped building.

First twelve months. Trustworthy baseline metrics that people quote in meetings; an alert set with a low false-positive rate; diagnostic data capture good enough that no significant incident goes unexplained for want of logs; at least two recurring failure modes permanently eliminated; fleet configuration visible and drift detectable; and one or two reliability engineers hired and productive.

Starting from the interview process and continuing into your career with us, you will be working by our four Operating Principles:

• Performance:
  High standards,…
