Job Description

Position: PLC Integration Engineer (PIE)

What You Will Do

Network & PLC Integration

  • Execute end-to-end network and PLC integration of Laminar’s edge devices into customer OT environments—both onsite and remotely—covering IP configuration, VLAN setup, DMZ architecture, firewall rules, and cloud connectivity.
  • Configure and troubleshoot industrial communication protocols including Ethernet/IP, Modbus TCP/RTU, and PROFINET to establish reliable data exchange between Laminar hardware and customer PLCs/SCADA systems.
  • Diagnose and resolve network issues in the field: invalid IP configurations, DNS resolution failures, NTP sync problems, and general IT/OT network outages affecting data flow.
  • Work alongside customer process, IT, and OT teams during deployment pilots to bring Laminar sensors and edge hardware online reliably and on schedule.
  • Contribute to productizing the integration process—identify what is manual and repetitive today and help engineer it away so deployments scale faster tomorrow.
  • Support Site Acceptance Test (SAT) completion and customer sign‑off in coordination with the broader FDE team.

Documentation & Feedback Loop

  • Systematically document integration challenges, workarounds, and field patterns; translate learnings into structured, actionable feedback for the edge device engineering team.
  • Build and maintain integration runbooks, network topology diagrams, and troubleshooting guides that reduce time-to-resolution for recurring issues.

Customer Support

  • Serve as a front‑line member of Laminar’s customer support function—monitor deployed site health, drive root‑cause analysis on connectivity and hardware issues, and create a feedback loop between field observations and product engineering to improve system resilience.
  • Actively support Laminar’s sales team on pre‑sales discovery calls and answer customer questions on cybersecurity, network/IT/OT architecture to get their approval.

Travel Requirement:

Up to 50% onsite at customer manufacturing facilities; typical visits 1–2 days.

About You – Required

  • Bachelor’s degree in Computer Science, Computer Engineering, or Electrical Engineering.
  • Hands‑on experience with PLC platforms and industrial communication protocols:

Ethernet/IP, Modbus (TCP and RTU), PROFINET, or equivalent.

  • Practical proficiency with Git/Git Hub, Python scripting, and Linux command‑line fundamentals.
  • Undergraduate coursework or equivalent demonstrated knowledge in networking fundamentals: IP addressing, subnetting, VLANs, DNS, NTP, and TCP/IP stack.
  • Comfortable getting hands dirty to debug data‑flow problems—you understand what a network trace tells you and you know how to follow a packet.
  • Portfolio of projects (academic, personal, or professional) demonstrating proficiency in networking, systems integration, debugging, or problem‑solving.
  • Strong cross‑functional communicator—able to work across customer IT teams, plant‑floor OT engineers, and internal software developers.
  • Willingness to travel up to 50% to customer sites as deployment schedules require.

About You – Preferred

  • Advanced Linux skills: shell scripting, systemd service management, network diagnostics (tcpdump, netstat, ip, nmap).
  • Experience with IT/OT convergence, Industry 4.0 architectures, or industrial network segmentation (Purdue model / ISA‑99).
  • Familiarity with time‑series or sensor data; ability to identify anomalies and performance degradation in data streams.
  • Experience with monitoring tooling, alerting infrastructure, or ticketing systems.
  • Startup mindset—adaptable, resourceful, and energized by building processes that don’t exist yet.

Benefits

  • Direct impact on product and culture.
  • Comprehensive benefits package including Medical, Dental, Vision, Life Insurance, Disability, Transportation benefit, Health and Wellness benefit, and more.
  • 401(k) plan with employer matching.
  • Equity.
  • Competitive salary and bonus opportunities.
  • Diverse and inclusive work environment.
  • Opportunities for growth and professional development.
  • Access to Greentown Labs’ extensive network of cleantech startups.
  • Salary range: $80,000 – $110,000 a year (subject to change).
  • Transportation benefit $90/month, health & wellness benefit $65/month, FSA, 12 company‑paid holidays.
  • Employer covers 100 % of individual health insurance premium for HMO medical, vision, and dental.
