Senior Software Engineer

Polaris Aviation is seeking two highly experienced engineers to help build browser-based, real-time aviation simulation and training platforms that integrate procedural logic, speech recognition pipelines, complex professional user interfaces, and regulatory compliance.

These are not dashboards, demo apps, or short-lived builds. They are long-running, mission-critical systems where correctness, determinism, and timing matter more than visual flair.

You should be deeply fluent in:

• Advanced HTML5 / CSS3 / JavaScript
• Real-time audio and ASR pipelines
• Simulation and state-machine design
• Complex UI architectures
• Working without heavy frameworks
• Diagnosing race conditions
• Translating real-world procedures into robust software

Experience with LLMs / SLMs is highly valuable.

This role demands patience, engineering rigor, documentation discipline, and the maturity to build training-grade software under a domain expert — not rewrite systems impulsively.

REQUIRED / DESIRED SKILL SETS

1. Core Frontend Engineering
   • Advanced JavaScript (ES6+)
   • Async/await, Promises, event-driven systems
   • State machines & lifecycle control
   • Performance optimisation for long-running browser sessions
   • Complex multi-panel UI layouts
   • Canvas & SVG rendering
   • Pixel-accurate interfaces for professional tools
   • Browser APIs (Web Audio, MediaRecorder, WebSockets, SSE)
   • Large legacy codebase maintenance
   • Simulation UI development (not CRUD dashboards)
   • Comfort with non-framework architectures

2. Real-Time Audio, Speech & Signal Handling
   • Browser-based real-time audio capture and processing
   • Latency management, buffering, silence detection
   • Speech recognition pipelines (with and without LLMs)
   • Phrase biasing, grammars, dictionaries
   • Handling accents, pauses, partial transcripts
   • Audio state synchronisation
   • Recognition start/stop race conditions
   • ASR post-processing and phrase normalization
   • Familiarity with Whisper, GPT Transcribe, local ASR models, Ollama, LM Studio

3. Simulation Logic & State Modelling
   • Complex state machines
   • Branching scenarios
   • Event-driven simulation
   • Experience with simulators (aviation, rail, maritime, military, industrial)

Ability to translate real-world operational procedures into deterministic software rules is critical.

1. Aviation / ATC Knowledge (High Weightage — Desirable)
   • Familiarity with ICAO procedures
   • Ability to interpret regulatory documents, AIPs, and circulars

2. Backend & Integration (Important)
   • API integration / REST
   • Authentication systems
   • Serverless or minimal backend architectures
   • PHP, Node.js, Python
   • Strong understanding of JSON, CSV, XML
   • Schema-driven design (JSON Schema, XML/XSD)
   • Stateless vs stateful architectures

3. Mapping & Visualisation (Important)
   • Leaflet, OpenLayers, OSM, Mapbox GL JS
   • Geospatial data handling
   • OpenAIP / OSM datasets
   • SVG overlays and performance optimisation
   • Canvas-based map rendering

4. UI/UX for Professional Systems
   • Dense, information-rich interfaces
   • Multi-monitor / large-screen layouts
   • Keyboard-first workflows
   • Low-distraction overlays
   • Industrial dashboards

5. Testing, Debugging & Reliability
   • Deep debugging skills
   • Timing analysis & race condition diagnosis
   • Logging, instrumentation, event timelines
   • Browser-level testing across Chrome, Edge, Firefox

We value engineers obsessed with “why did this break?” rather than quick fixes.

1. Security, IP & Deployment Awareness
   • Code obfuscation strategies
   • Secure deployment practices
   • Compliance-oriented design

2. Engineering Mindset & Work Ethic
   • Ability to collaborate with domain experts
   • Comfort with deep technical discussions and iterative refinement
   • “Understand first — don’t rewrite blindly.”
   • Strong documentation discipline
   • Commitment to building training-grade software

3. AI / LLM Foundations
   • Experience installing, integrating, and operating LLM/SLM systems
   • Python / JavaScript API usage
   • Cloud and local model deployments
