PTP / Network Timing Consultant (IEEE-1588) — Part-Time

Location : Hyderabad, India

About the engagement

Our edge Box is the campus time authority. We need a specialist to design and validate precise clock discipline across cameras, mics, and sensors using PTP (IEEE-1588) , with NTP / chrony fallbacks, so cross-modal CEP remains trustworthy.

Time : 3–6 hrs / week during design / commissioning; ad-hoc thereafter. Location : Remote.

Works with : Edge Perf / Sync engineer, Rohit (platform), DSP consultant (for Δt budgets).

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 (
