Remote Software Engineer - AI-Driven Ops & Real-Time Systems

Hydrodriveusa; Irvine (CA); On-site; USD 120,000 - 140,000; Full time

Job summary

HydroDrive LLC in Irvine, CA is hiring a Software Development Engineer for full-time remote work. You will own development of internal applications, from staff-facing web products to backend services and AI-assisted workflows, shipping production-ready improvements with strong independent judgment.

You'll collaborate across product and infrastructure, implement robust PostgreSQL models, integrate Twilio and other services, and apply AI techniques responsibly in real operations.

Qualifications

• 3+ years of professional software development experience delivering and maintaining production web applications or backend services.
• Backend API development experience in Node.js/TypeScript or Python, with a working understanding of asynchronous programming and RESTful service design.
• Hands-on PostgreSQL experience covering relational data modeling, SQL, indexes, transactions, schema migrations, query debugging, and an ORM such as Prisma.
• Practical experience applying AI in production software, such as integrating language-model APIs, retrieval or vector search, tool/function calling, prompt contracts, guardrails, or evaluation workflows.
• Demonstrated fluency with modern AI coding assistants and agents as part of a daily engineering workflow, including writing effective instructions, providing useful context, reviewing generated changes critically, and correcting failures.
• Experience integrating authenticated third-party APIs, webhooks, file or object storage, and external services while handling retries, timeouts, partial failures, and sensitive credentials.
• A track record of debugging across frontend, backend, database, and integration boundaries and adding focused automated tests to prevent regressions.
• Clear written communication and the ability to translate an operational problem into a scoped technical solution.

Responsibilities

• Continuously develop and improve HydroDrive's internal operations copilot, fleet and calendar platform, and real-time voice-attendant systems based on day-to-day business needs.
• Build reliable, accessible full-stack features with React, Next.js, TypeScript, server-rendered interfaces, route handlers, and well-structured backend APIs.
• Develop and maintain Python and FastAPI services for asynchronous workflows, WebSockets, real-time audio, telephony events, and background processing.
• Apply AI technologies where they create measurable business value, including LLM APIs, retrieval-augmented generation, embeddings and vector search, tool calling, structured outputs, prompt design, evaluations, and human-in-the-loop safeguards.
• Use AI coding assistants and agentic development tools throughout daily work for research, planning, implementation, debugging, test creation, code review, and documentation while independently validating their output.
• Design PostgreSQL data models, indexes, queries, transactions, migrations, and backfills that preserve data integrity as operational workflows evolve.
• Integrate and troubleshoot third-party systems such as Twilio, speech-to-text and text-to-speech providers, Turo data feeds, Lark, email delivery, and object storage.
• Strengthen authentication, role-based authorization, input validation, auditability, privacy controls, tests, and technical documentation across the applications.
• Partner directly with operations staff and the DevOps Engineer to turn recurring manual work into maintainable software and release changes safely.
