Note: The job is a remote job and is open to candidates in USA. Kings III Emergency Communications operates LiftNet, a platform for monitoring and managing elevators, escalators, and moving walks. The company is seeking a Full-Stack Engineer to own features across React/TypeScript, Go cloud APIs, and Rust services, with a primary focus on Rust. The role includes distributed-system development, real-time interfaces, industrial protocol integration, Linux operations, AWS infrastructure, and regression validation.
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. However, this role will center around Rust
- Do deep Rust work on the VTS (Vendor Translation Services) layer and the LiftNet client/server re-architecture, where your specialization matters most
- 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
Skills
- Bachelor's degree or equivalent experience
- 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
- Masters Degree and other engineering credentials a plus
- 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)
