About the engagement

Our edge Box is the campus time authority. We need a specialist to design and validate precise clock discipline

Time

Works with

What you’ll do

  • Design campus

    timing architecture

    : grandmaster selection (GNSS vs Box), boundary/transparent clocks, VLAN/QoS.
  • Deploy and tune

    linuxptp

    (ptp4l, phc2sys, pmc) and chrony; document NIC/switch configs (Cisco/Arista/Juniper or equivalent).
  • Establish

    acceptance tests

    : skew/jitter targets, wander, step response; create Grafana dashboards for drift and holdover.
  • Write commissioning SOPs: firmware, servo parameters, delay mechanisms (E2E vs P2P), announce intervals, clock classes.
  • Define failure modes & fallbacks: holdover behavior, NTP degrade, alarms when skew > thresholds.

Must-have

  • 7+ years with PTP in production (broadcast/industrial/finance/AVB/gPTP).
  • Hands-on with boundary/transparent clock switches, NIC PHC, and Linux timing stack.
  • Measurement discipline: how to

    prove

    sub-millisecond sync on LAN; tooling & methods.

Nice-to-have

  • Multi-site timing over WAN; GNSS grandmaster design and antenna siting.
  • Experience aligning timing for

    audio arrays

    and camera fleets simultaneously.
  • Security hardening for PTP/NTP (ACLs, VLANs, management plane).

Deliverables (first 3–5 weeks)

  • Written

    Timing Design Doc

    (topology, configs, targets) + switch/NIC templates.
  • Commissioning checklist & training for our engineers.
  • Dashboards and alerting (clock skew histograms, offset heatmaps); final sign-off report with measured p95/p99 skew.

Selection Criteria:

·     Live/Whiteboard/IDE (90-120 min) around Architecture design, Linux timing stack, Commissioning & measurement, Failure modes & fallbacks, Security & Ops

  • ·     Take-Home (< 6hours, due in 48h)
