Sedna Introduction  

At Sedna, we’re building the future with robotics. Our work is integrating robotics and automation into industries like construction and mining. If you’re passionate about cutting-edge technology, solving complex problems, and building systems that push the limits of what is possible in robotics and automation, Sedna is where your skills can make a global impact. 

We are a US based company with strong South African roots. Our business started in Joburg in 2005 and later moved to the USA. We are now building out our engineering office’s in Cape Town (Century City) and Joburg (Greenstone Hill) to support our US operations and customers.  

Job Overview  

We are seeking a network cabling design engineer to produce all CAD drawings and design documentation for a US-based technical facility with high-density electrical and network infrastructure. The position is based in Century City, South Africa. 

The successful candidate will take the lead on structured data cabling and network infrastructure design — this is the core focus of the role. Familiarity with power distribution design is a valuable bonus but not a requirement. 

Key Responsibilities:

Structured Data Cabling & Network Infrastructure Design (core focus of the role) 

  • Understand the logical network topology (core, distribution, and access layers) well enough to translate it correctly into physical cabling — knowing which equipment, ports, and links connect where, and why. 
  • Liaise with network/IT teams to confirm switch-to-rack mappings, uplink counts, and redundancy/failover paths before finalizing physical routing and port assignments. 
  • Lead the design of fibre and copper network infrastructure serving high-density equipment racks and distribution frames. 
  • Select appropriate fibre types for each part of the network: backbone runs, high-speed links between racks and equipment. 
  • Design the complete fibre plant layout — routes, ODF positions, splice enclosure locations, bend radius management, and slack storage allowances. 
  • Specify termination and connector types (LC, SC, MPO/MTP), and recommend pre-terminated trunk systems vs field-terminated solutions based on density and flexibility requirements. 
  • Produce fibre schedules showing core counts, link lengths, loss budget calculations, and test acceptance criteria to TIA-526-14 (multimode) and TIA-526-7 (single-mode). 
  • Design copper cable runs to appropriate TIA-568 category specifications based on application, distance, and performance requirements across the site. 
  • Produce patch panel and rack elevation drawings showing port assignments, cable labelling conventions, and patch lead management, ensuring each connection reflects its correct place in the overall network design. 
  • Define demarcation points between copper horizontal runs and fibre backbone, coordinating the two media types into a coherent, scalable topology. 

Drawing Production & Documentation 

  • All design output produced in AutoCAD drawing packages — routing plans, containment layouts, rack elevations, cable schedules, and as-built records. 
  • Manage drawing layers, naming conventions, and title blocks to a consistent standard suitable for multi-discipline project environments. 
  • Produce cable schedules cross-referenced to drawing references: cable ID, type, origin, destination, length, and route. 
  • Issue drawings at appropriate stages (preliminary, for-construction, as-built) and manage revision control throughout the project. 
  • Work from and overlay onto architect and M&E base drawings without disrupting existing drawing structure. 

Design Coordination 

  • Work remotely with the project team, providing drawing packages and responding to design queries from on-site contractors. 
  • Attend design review meetings (remote or on-site as required) and incorporate feedback into revised drawing issues. 
  • Flag design clashes or space constraints early and propose solutions — particularly in compact rack and under-floor areas. 
  • Liaise with the AHJ (Authority Having Jurisdiction) submission process where design drawings are required for permit applications. 

Power Cabling Design (beneficial, not essential) 

  • Exposure to HV/LV power distribution design— e.g. routing drawings for power distribution to racks, PDUs, and UPS systems. 
  • Familiarity with sizing and scheduling cables for 277/480V three-phase US distribution. 
  • Any prior awareness of NEC NFPA 70 compliance (Articles 645, 230, 250, 310). 
  • Establish and adhere to industry-standard best practices and design principles for the routing, separation, support, protection and installation of electrical power and network communication cabling. 
  • Ensure safety, reliability, maintainability and compliance with applicable codes and standards. 
  • Candidates without power design experience are still strongly encouraged to apply if their network/data cabling design background is strong. 

Qualifications & Experience 

  • Minimum 5 years relevant experience in a network / structured data cabling design role, ideally with exposure to high-density rack environments. 
  • Solid understanding of network architecture and topology (core/distribution/access layers, redundancy paths, uplink structures) — this candidate needs to know what connects where and why, not just how to draw or install it. 
  • BSc, BTech, BEng or NQF6 specializing in Information Technology, Electrical Engineering, Telecommunications, Computer, Computer Science, Electronics or a related field. 
  • If you have more than 5 five years’ relevant experience, tertiary education is not crucial. 
  • Please supply proof of professional certifications to prove qualification (e.g. Cisco Certified Network Professional Certification). 
  • Strong working knowledge of structured cabling standards (TIA-568, TIA-526) and fibre network design — this is essential. 
  • Experience with HV/LV power cabling design or pipe layout/routing beneficial, but is not essential. 
  • Experience using AutoCAD or similar tool. 

Skills & Competencies 

  • Problem solving and critical thinking 
  • Attention to detail 
  • Time management 
  • Cross-functional collaboration 
  • Adaptability and self-motivation 
  • Excellent communication skills  
  • Proactive and collaborative approach to teamwork 

Additional Beneficial Skills & Certifications (advantageous) 

  • BICSI RCDD (Registered Communications Distribution Designer), or actively working towards it. 
  • CFOT (Certified Fiber Optic Technician, ETA/FOA). 
  • BICSI Installer/Technician certification (INST1, INST2, or TECH) 
  • Vendor design/certification exposure — e.g. Corning, Panduit, CommScope/SYSTIMAX, or Fluke Networks. 
  • Autodesk Certified Professional (AutoCAD). 
  • Working knowledge of Revit or BIM-based coordinated drawing workflows. 
  • Exposure to cable management or infrastructure management software (e.g. Ekahau, iTracs, Device42, or similar). 
  • Familiarity with ANSI/TIA-942 or ISO/IEC 11801 as broader reference standards. 
  • Experience independently producing loss budget calculations and test acceptance documentation, rather than working from a template. 
  • Prior experience collaborating remotely with US-based teams or clients.
