Role Overview

The Senior Backend Engineer will lead a core backend domain and manage it end to end. This is an ownership role, not an extra-pair-of-hands position. As SignWow expands across regions, the backend scope will grow to include provisioning, call record handling, reporting, and the integrations that connect these systems. The Senior Backend Engineer will lead one of these domains, shape its architecture, and deliver it into production.

Key Responsibilities

• Lead a core backend domain end to end, such as provisioning, call-record and reporting pipelines, or integrations
• Build services and APIs with clean, well-tested, well-documented code.
• Design data models for call records, reporting, and cross-region reconciliation.
• Develop integrations across identity, telephony, emergency services, and reporting feeds.
• Improve performance, scale, and reliability of the services assigned to you.
• Deliver region-aware backend features as SignWow expands into new markets.
• Contribute to code reviews, testing, design documentation, and the on-call rotation.
• Work in a small team with a short path from idea to production, where your work reaches real users quickly.

Skills & Experience Required - Essential

• Senior backend experience with a strong portfolio.
• Proficiency in TypeScript / Node, or a comparable backend language.
• Strong PostgreSQL and relational data modeling.
• Solid API design and a working understanding of distributed systems.
• Experience with queues and event-driven services.
• Strong AWS or comparable cloud experience, plus containers and CI/CD.
• Uses AI tools to work faster while retaining responsibility for design, architecture, and judgment calls.
• Self-directed and comfortable carrying a problem end to end in a fast-moving team.

Skills & Experience Required - Desirable

• Real-time, WebRTC, or telephony exposure.
• High-volume or low-latency systems.
• Multi-region or multi-tenant data.
• Exposure to native mobile, such as Swift or Kotlin, is a plus.
• American Sign Language (ASL) knowledge is a strong plus.

Our Stack

• PostgreSQL, Redis, websocket, and event-driven services.
• TypeScript/ Node.
• WebRTC-based real-time media.
• Cloud infrastructure, containers, infrastructure-as-code, and CI/CD.
• Async-first workflow with GitHub, Linear, Slack, and Notion.

What We Offer

• Lead a real domain, not a backlog queue.
• Real responsibility and direct work with the founders, without management layers.
• We use AI to move faster, not to think for us. You bring the design judgment and architectural decisions; AI helps you execute.
• Flexible, results-focused remote work.
• Join a Deaf-led company making everyday communication more accessible.
