• Designing, building and shipping systems that power JOIN. • Working with our databases and infrastructure to keep things reliable as we scale. • Jumping into mobile or web frontend work when the team needs it. • Owning your work end to end from prototyping to production release. • Using AI tools (including coding agents) to work faster and better: we give you the freedom to use them how you see fit

• Help the Full Stack Developers to build the core and support systems for a communication platform. • Help maintenance of the core and support systems by constantly updating the source codes and allied repositories. • Assist the Full Stack Developers with technical documentation and maintain active tech repositories for all tech activities carried out.

• Ship A- product at A+ timeline • Understand product requirements and provide solutions • Build products for the ops team and customers

• Coordinate directly with clients, project managers, operations personnel, and other stakeholders to identify project needs, define design requirements, and support successful project execution. • Develop project scoping documents, design criteria, engineering work plans, technical memoranda, proposals, and cost and schedule estimates. • Support the design and modernization of natural gas transmission and distribution facilities, including pipelines, distribution regulator stations, pressure control systems, metering facilities, and related infrastructure. • Develop engineering designs for the installation of gas control, automation, and real-time remote monitoring equipment at existing and new facilities throughout Southern California. • Prepare designs involving pressure, flow, and temperature transmitters; gas detection equipment; remote control valves; control valves; flow meters; pressure regulators; programmable logic controllers; remote terminal units; control panels; and communications equipment. • Support the design of electrical power, conduit, cabling, grounding, communications, and control infrastructure associated with instrumentation and automation improvements. • Develop and review pipeline routing, station layouts, piping modifications, equipment arrangements, valve configurations, tie-in details, and related mechanical design documents. • Perform process and hydraulic calculations, pressure-drop evaluations, equipment sizing, valve sizing, relief-system evaluations, and other engineering calculations. • Evaluate existing facility conditions and determine modifications required to accommodate new equipment, instrumentation, controls, piping, electrical systems, and communications infrastructure. • Prepare and review engineering drawings and documents, including: Process Flow Diagrams Piping and Instrumentation Diagrams Plot plans and equipment layouts Pipeline alignment and profile drawings Instrument loop diagrams Control schematics and wiring diagrams Cause-and-effect matrices Control narratives and philosophies Shutdown and alarm philosophies Instrument indexes and I/O lists Equipment, valve, and line lists Demolition and construction drawings. • Develop control narratives, alarm setpoints, shutdown logic, interlocks, and operating sequences in coordination with operations, gas control, SCADA, and automation teams. • Coordinate SCADA integration requirements, communications architecture, point mapping, alarm configuration, and data exchange between field equipment and remote monitoring systems. • Support point-to-point verification, loop checks, functional testing, factory acceptance testing, site acceptance testing, startup, commissioning, and performance testing. • Participate in field investigations, site walks, constructability reviews, design reviews, and project meetings. • Review existing drawings, records, survey information, inspection reports, and field conditions to confirm design assumptions and identify potential project constraints. • Coordinate with civil, structural, electrical, mechanical, pipeline, corrosion, survey, environmental, permitting, land, right-of-way, construction, and operations teams. • Prepare requests for quotation, evaluate vendor proposals, respond to technical clarifications, and prepare technical bid evaluations and equipment recommendations.
