Description

Senior Frontend Engineer role building Minerva Frontline, a command and control software that connects operators to autonomous systems in real time. The engineer shapes a robust, high-performance frontend architecture under extreme constraints such as low-bandwidth networks and air-gapped devices. The work combines hands-on engineering with agentic AI workflows, setting architectural guardrails and solving novel integration and quality problems.

Responsibilities

Engineer highly optimized frontend solutions handling high-frequency telemetry and asynchronous data streams while minimizing computational load to preserve battery life on field devices
Translate complex data into immediate situational awareness and build deterministic, error-tolerant interfaces that manage operator cognitive load under stress
Act as a strategic sparring partner: align rapid delivery with long-term system health and challenge APIs and data structures when needed
Set strict architectural guardrails for agentic AI workflows, validate outputs and solve novel integration and quality challenges
Build high-performance framework-less user interfaces with Vanilla TS and Web Components that function under low bandwidth and air-gapped networks
Raise the level of the team by sharing knowledge, providing impulses for system design and facilitating open fact-based discussions

Requirements

Deep practical expertise in Vanilla TypeScript/JavaScript and the native web platform including DOM API, Event Loop and Memory Management
Constraint-driven engineering: anticipate hardware realities by managing latency, handling data bursts and optimizing for constrained compute and battery life
Practical experience integrating agent-based coding tools, structuring architecture for AI and rigorously validating its output
Mission-oriented execution: balance rapid delivery with a critical mindset and evaluate technical decisions from the operator's perspective
Strong team player with zero ego: moderate technical decisions, compromise and put the mission above personal ego
Nice to have: practical experience building comprehensive design systems, ideally using native Web Components
Nice to have: experience with real-time data streaming architectures such as WebSockets and WebRTC or high-frequency telemetry
Nice to have: experience in geographic mapping, GIS or complex Canvas/WebGL rendering in the browser
Nice to have: experience working with unmanned systems, ideally in command-and-control, mission management or operator-facing software
