Note: The job is a remote job and is open to candidates in USA. Domu Technology Inc. is building the agentic infrastructure for the future of the world's largest financial institutions. As a Software Engineer, you will be responsible for developing core product features and working on complex systems that integrate with legacy financial infrastructures.
Responsibilities
- Build and own core product features: Backend systems, APIs, voice infrastructure, wherever the product needs you. Code ships daily and goes live for Fortune 500 clients
- Work on things most engineers never touch: telephony systems, real-time voice processing, and integrations with legacy financial infrastructure. The problems are hard. That's the point
- 95%+ of your time will be coding and building
- We're looking for engineers who can own one of these areas: the orchestration layer that coordinates our voice AI systems, infrastructure scaling and low-level performance, security as a generalist building for Fortune 500 financial institutions, or product engineering close to users finding high-leverage wins
- Know what it feels like when things are working: real customers, real revenue, a product people actually need. You also know the chaos, the pace, the things that break at the worst possible time. You've seen both sides and you want to do it again with a team that's already found traction
Skills
- 3+ years of experience as a software engineer
- Previously worked at a Series A (or similar stage) startup and went through the same hypergrowth challenges Domu is facing
- Experience dealing with legacy systems and refactoring them into sustainable, scalable architectures
- Strong backend fundamentals - can own features end-to-end from design to production
- Proficiency in TypeScript and/or Python
- Telephony/Voice infrastructure - SIP, SRTP, WebRTC, or platforms like Telnyx, Twilio, LiveKit
- High-throughput distributed systems - queue workers, event-driven architectures, handling 1M+ daily transactions
- PostgreSQL at scale - query optimization, replication, connection pooling
- Kubernetes - production deployments, scaling stateful services
- Real-time data pipelines - ClickHouse, Kafka, or similar OLAP/streaming solutions
- AWS infrastructure - SQS, containerized deployments
- Compliance-conscious environments - SOC 2, ISO 27001, or fintech/enterprise security requirements
- Experience with AI/ML integrations in production (LLMs, voice AI)
- Familiarity with contact center / dialer systems
- You've been through the early stages of a startup before
- You care about the craft. You want to build something good, not just something that works
