Full Stack Engineer - Rust

Kings III Emergency Communications • Coppell, TX

2d • $170,000 - $180,000 • Remote

About The Position

This role is for a senior full-stack engineer with deep specialization in Rust, responsible for taking ambiguous problems and driving them to completion with minimal oversight. The engineer will build across the entire stack, including the React/TypeScript front-end, the Go cloud API (LiftCloud), and the Rust services at the core of the platform (VTS layer and LiftNet client/server re-architecture). The primary focus will be on Rust, where the hardest and highest-value work resides. The role involves owning features vertically, sharing day-to-day ownership with a principal engineer and another full-stack engineer to mitigate key-person risks, and contributing to LiftNet’s strategic roadmap, including its evolving architecture, predictive analytics, and the LN2 Integrator automated-QA effort. The ideal candidate values ownership, minimal oversight, a small team environment, Rust development, and remote work.

Requirements

• Bachelor's degree or equivalent experience; Masters Degree and other engineering credentials a plus.
• 5-7 years of Rust engineering experience with senior-level competency.
• Genuine full-stack capability: production experience building front-ends in React/TypeScript and working server-side APIs (we run Go in the cloud - you must be able to read and extend it).
• Client/server distributed-system design experience aligned to the LiftNet 3 direction.
• Demonstrated self-starting autonomy - able to own a domain end to end with minimal direction (non-negotiable for this role).
• Comfort across the full architecture: the edge layer (Raspberry Pi, binary/serial), the VTS layer, the Go cloud, and AWS (EC2, PostgreSQL/RDS, QuestDB).
• Deep, hands-on Linux expertise - operating, debugging, and hardening Linux systems from the command line (systems, process/network/file-system troubleshooting, bash scripting, log analysis); both the edge devices (Raspberry Pi) and the cloud services (EC2) run on Linux.
• Able to build, package, and deploy services on Linux - cross-compilation for ARM/edge targets, containers, and standard build toolchains.
• Pragmatic for a small, fast-moving company; automation-first, low ego; communicates bottom-line-first.

Nice To Haves

• Front-end depth on data-heavy, real-time UIs - mapping (Mapbox GL/Leaflet-class), live status, and performance tuning of dense views (a plus).
• Test-automation mindset - regression validation against golden datasets and packet-level (Wireshark) verification (a plus).
• Industrial/OT protocol familiarity - OPC UA, Modbus, serial integration (a plus).
• AWS infrastructure fluency - environment duplication (Dev/Staging/QA) and security-group hardening (a plus).

Responsibilities

• Own features end to end across the stack - front-end (React/TypeScript), cloud API (Go/LiftCloud), and Rust services - rather than working a single layer.
• Do deep Rust work on the VTS (Vendor Translation Services) layer and the LiftNet client/server re-architecture.
• Read and extend the Go cloud API and build the UI that consumes it correctly, keeping API contracts and data shapes coherent across the stack.
• Build data-dense, real-time interfaces - dashboards, map views, status panels - that stay performant and legible for building operators and field technicians on desktop and tablet.
• Design and build client/server distributed-system components aligned to the LiftNet re-architecture.
• Work across the full architecture: the edge layer (Raspberry Pi, binary/serial protocols), the VTS translation layer, the Go cloud, and AWS (EC2, PostgreSQL/RDS, QuestDB).
• Operate, debug, and harden the Linux-based services that run on the edge devices and in the cloud.
• Integrate and translate industrial/OT controller protocols (OPC UA, Modbus, serial).
• Build regression validation against golden/blessed datasets and packet-level (Wireshark) verification, supporting the LN2 Integrator effort.
• Contribute to AWS environment setup (Dev/Staging/QA) and security-group hardening, complementing the SOC 2 readiness effort.
• Partner with the principal engineer and the second full-stack engineer to split ownership across the stack and reduce day-to-day escalation drag.
• Own day-to-day work across front-end, cloud, and Rust services reliably, without principal-engineer rescue.
• Deliver predictable, on-time turnaround on committed customer features.
• Take independent ownership of at least one vertical domain (UI through Rust service) within the first months.
• Reduce key-person risk across the VTS, the Rust backend, and the front-end.

Benefits

• Medical insurance with 1 HSA and 2 PPO plan options
• Flex Spending Account (FSA)/Dependent Care FSA
• Dental, vision, life, short- and long-term disability insurance
• Critical illness and hospital indemnity plans
• 401k with company contribution
• Employee Assistance Program (EAP)
• Company paid telemedicine 24/7 access
• Wellness Program
• Employee discount program
• 8 paid holidays, plus 1 floating holiday
• 15 days of PTO accrued in year 1
• Generous referral bonus program
• Work life balance (a must!)
• Team building, attendance at our annual kickoff each January, and other fun events
• Relaxed professional dress code
