Who We Are
OmniDimension is on an exhilarating journey. We're building an AI-powered platform that empowers developers and enterprises across 150+ countries to effortlessly create and deploy reliable Voice AI agents. This isn't your average 9-to-5 role. We thrive on passion, ownership, and pushing boundaries, and the impact we create is extraordinary. We're growing fast and would love to bring passionate builders along for the journey.
Who We are Looking For
We're looking for a Senior Software Engineer who has already built and operated real-time systems at scale and wants to go deep at the intersection of Voice AI, telephony, and agentic AI. You've felt the pain of keeping a high-traffic product alive, you know how to make a single feature hold up when it suddenly has to serve 10x the load, and you're genuinely plugged into where the AI space is heading.
This is a hands-on, high-ownership role on the core Voice AI platform - the orchestration, bulk calling, telephony, and messaging layers that thousands of live customer calls run through every day. You'll own features end-to-end: designing them, shipping them, scaling them, and keeping them healthy in production.
You are someone who:
- Constantly asks "Why?" and dives deep to find the real answer.
- Enjoys rapid prototyping but takes pride in rock-solid, production-grade systems.
- Has strong, thoughtful opinions yet stays open-minded - able to disagree and commit.
- Understands the big picture and enjoys working across backend, services, and frontend to deliver complete solutions.
Key Responsibilities
- Build and ship new features across the core voice platform - orchestration, bulk calling, telephony, WhatsApp, and chat.
- Scale individual features and services for high concurrency and traffic: load handling, caching, connection management, and graceful degradation under pressure.
- Diagnose and fix complex production issues fast - find the root cause, ship the fix, and add the guardrail so the same class of problem doesn't recur.
- Work on real-time telephony infrastructure: call routing, SIP/RTP/WebRTC, PSTN, media processing, and STT/TTS/LLM pipelines.
- Build and improve agentic systems - agent orchestration, multi-agent workflows, state management, tool use, and agent memory.
- Strengthen observability, reliability, and redundancy - logging, metrics, tracing, alerting, retries, and failover.
- Optimize for latency, reliability, and cost across live call flows.
- Evaluate and integrate new AI models, frameworks, and infrastructure as the space moves.
- Own your components end-to-end and collaborate closely with senior engineers on the harder architectural calls.
Mandatory Qualifications
- 4+ years of full-stack development, primarily Python backend (modern frontend a plus).
- Proven experience operating systems at real production scale - 1,000+ live users / high-concurrency infrastructure.
- Deep, demonstrated ability to scale individual features - not just theory, but having taken a specific feature or service and made it hold up under heavy, growing load.
- Strong knowledge of telephony protocols - SIP, RTP, WebRTC, PSTN - and integration with providers like Twilio, Telnyx, Plivo, or Vonage.
- Hands-on experience with agentic frameworks and multi-agent architectures, and genuine awareness of the current AI / LLM landscape.
- Deep understanding of relational databases (PostgreSQL or similar): schema design, indexing, query optimization.
- Solid experience deploying and operating services on AWS (or comparable cloud).
- A proven track record of debugging under production pressure and a real ownership mindset.
Highly Desired Skills
- Experience integrating STT / TTS / ASR systems.
- Familiarity with data streaming and real-time technologies (Kafka, WebSockets).
- Experience evaluating, fine-tuning, or monitoring LLMs.
- Observability tooling (Prometheus, Grafana, Sentry, OpenTelemetry).
- CI/CD pipelines, Infrastructure as Code, and containerization (Docker).
- Proficiency with React / React Native for frontend or mobile work.
Why OmniDimension
- Work on groundbreaking technology at the cutting edge of Generative and Voice AI.
- Directly impact a platform used by top enterprises and innovative builders globally.
- Join a passionate team that values ownership, innovation, and relentless execution.
- Thrive in a culture that embraces hard problems, rewards bold ideas, and celebrates people who ship.
- This isn't just another job - it's a chance to help shape the future of voice-driven AI interactions worldwide.
