Rust Developer

About Domesly:

At Domesly, we are pioneering real-time, active voice-coaching technology for high-performance cyclists. While legacy tools focus on pre-ride planning (TrainingPeaks, Zwift) or post-ride post-mortems (Strava, Intervals.icu), Domesly acts as an active digital Directeur Sportif while the rider is pedaling. By pairing live sensor telemetry (Bluetooth power meters, HR monitors, cadence) with real-time edge AI models and open-ear bone conduction audio hardware, we deliver instantaneous voice directives (pacing, W balance threshold protection, interval timing) directly to the rider without taking their eyes off the road or blocking ambient traffic noise.

The Opportunity: Rust Developer:

We are seeking a hands-on, high-velocity Rust Developer to build and own the core real-time processing engine for Domesly at our Vizag innovation hub. In this role, you will lead the development of our high-performance systems code—focusing on BLE device integrations, sub-150ms biometric edge computing, and cross-platform Rust targets for mobile and embedded devices. Working side-by-side with our engineering team, you will help scale our tech stack from a working prototype to global mass commercialization.

Key Responsibilities

• System Architecture & Real-Time Engine (Rust): Architect and build the core edge-processing engine in Rust to handle live Bluetooth Low Energy (BLE) sensor streams (power, cadence, heart rate) and compute physiological metrics (e.g., live W balance, fatigue curves) with sub-150ms latency.
• Low-Latency Audio Logic: Work on adaptive text-to-speech (TTS) pipelines to deliver concise, context-aware audio directives via bone-conduction hardware.
• Mobile & Ecosystem Integration: Package and bridge core Rust telemetry and calculation libraries into iOS and Android application layers. Support two-way API integrations with third-party cycling platforms (Garmin, Wahoo, Strava, TrainingPeaks, Intervals.icu, Zwift).
• Hardware & Firmware Collaboration: Partner with embedded hardware teams and partners to optimize power management, BLE protocol stability, and firmware integration for open-ear transducers in high-wind environments.
• Engineering Best Practices (Vizag Hub): Help establish best-in-class Rust testing, automated benchmarking, memory optimization, and CI/CD pipelines for cross-platform releases and firmware over-the-air (OTA) updates.

What We Are Looking For:

Professional systems engineering experience with strong, demonstrated proficiency in Rust.

Core Tech Stack Proficiency:

• Deep expertise in Rust (concurrency, memory safety, async I/O with tokio/async-std, and cross-compilation for mobile/embedded platforms via cxx or uniffi).
• Hands-on experience with Bluetooth Low Energy (BLE) protocols, streaming binary data, and edge computing.
• Familiarity with C/C++ (for system/firmware interop), Python, and general mobile architecture (Swift/Kotlin/Flutter integrations).
• Telemetry & Real-Time Processing: Experience handling real-time data pipelines, mathematical operations, or lightweight AI/ML models on resource-constrained devices.
• Domain Passion: High affinity for sports technology, wearables, or endurance sports (cycling, running, triathlon). Being a cyclist who understands power meters, FTP, and training metrics is a big plus!
• Location: Based in or willing to relocate to Visakhapatnam (Vizag) to work with our core R&D team.
