Senior AI Backend Engineer - Production-Grade Agents Remote

BrightNight; Austin (TX); Remote; USD 150,000 - 210,000; Full time

Job summary

BrightNight is seeking a Senior AI/Backend Engineer to build the next generation of agentic AI systems powering our PowerAlpha platform. You will design, develop, and productionize AI agents that automate complex engineering, commercial, and operational workflows.

You will collaborate with software engineers, AI specialists, and SMEs to combine large language models with proprietary optimization models and data for faster decisions and higher quality outcomes.

Qualifications

• 5+ years of software engineering experience with a strong focus on backend development.
• Extensive hands-on experience developing Generative AI applications, including LLM prompting, retrieval, tool calling, and agent frameworks.
• Expert-level Python development experience building production APIs, backend services, asynchronous applications, and data access layers.
• Experience building and deploying agentic workflows involving multi-step reasoning, tool orchestration, memory, state management, and human-in-the-loop processes.
• Strong software engineering fundamentals, including rigorous unit, integration, and end-to-end testing practices.
• Experience evaluating and improving non-deterministic AI systems.
• Practical understanding of where LLMs are most effective—and when deterministic algorithms or optimization models are the better solution.
• Ability to own complex technical initiatives from architecture through deployment while mentoring other engineers.

Responsibilities

• Design, build, and deploy production-grade AI agents that integrate with BrightNight's proprietary optimization models.
• Develop scalable backend services supporting agent workflows, APIs, tool execution, memory, persistence, streaming, and observability.
• Build optimization agents capable of scenario generation, ranking, uncertainty analysis, and decision support.
• Create robust data ingestion and normalization pipelines that transform complex external data into standardized, validated inputs.
• Develop comprehensive testing frameworks, including unit, integration, end-to-end, and evaluation harnesses for probabilistic AI systems.
• Improve agent learning through feedback loops, knowledge capture, validation, and continuous refinement.
• Partner with engineering, commercial, and operations experts to encode domain expertise into AI skills and knowledge bases.
• Design safe, reliable human-in-the-loop workflows with appropriate approval checkpoints.
• Monitor, measure, and continuously improve agent performance, quality, and operational efficiency.
