About The Position

Bright Vision Technologies is seeking a Prompt Engineer to define and lead organization-wide strategy, patterns, and tooling for prompt design, agentic workflows, and LLM-based application architectures. The role combines practical expertise with modern LLMs and the development of reusable design patterns, evaluation frameworks, and developer tooling that support multiple teams and use cases. The ideal candidate has shipped LLM-powered products to production, understands prompt design patterns and agent architectures, and applies LLM techniques with sound judgment and responsibility. The Prompt Engineer will establish standards and reference architectures; design prompts, retrieval strategies, and agentic systems; develop evaluation frameworks, internal tools, guardrails, and safety patterns; and collaborate with model engineering teams. The role also includes reviewing application designs, mentoring engineers and applied scientists, conducting red-team exercises, optimizing latency, cost, and quality, documenting reusable guidance, and tracking advances in LLM capabilities and research.

Requirements

Bachelor’s or Master’s degree in Computer Science, Computational Linguistics, or a related field.
Ten or more years of software engineering experience, with significant time spent on LLM-based applications.
Demonstrated experience shipping LLM-powered products to production.
Deep familiarity with modern LLM APIs and agent frameworks.
Strong understanding of retrieval-augmented generation, embeddings, and vector databases.
Experience designing evaluation pipelines for non-deterministic systems.
Strong Python skills and comfort with modern application frameworks.
Solid grasp of responsible AI principles, including safety and policy considerations.
Excellent written and verbal communication skills.
Track record of mentoring engineers and influencing technical direction.

Nice To Haves

Public writing, talks, or open-source contributions on LLM application development.
Experience with multi-agent architectures and complex tool-use systems.
Familiarity with fine-tuning workflows and when to choose them over prompting.
Exposure to product domains such as customer support, coding assistants, or analytics agents.
Experience integrating LLMs into enterprise software systems with strict compliance requirements.

Responsibilities

Define organization-wide standards, patterns, and reference architectures for LLM-based applications.
Design prompt structures, instruction templates, and retrieval strategies for production use cases.
Architect agentic systems incorporating tool use, planning, memory, and multi-step reasoning.
Lead the design of retrieval-augmented generation pipelines, including chunking, indexing, and reranking strategies.
Develop evaluation frameworks for prompt quality, agent reliability, and end-to-end task success.
Build internal tooling and libraries that accelerate LLM application development across teams.
Establish guardrails, safety filters, and policy enforcement patterns for LLM-powered products.
Collaborate with model engineering teams on prompt-model co-design and fine-tuning opportunities.
Conduct technical reviews of LLM application designs across product teams.
Mentor engineers and applied scientists on prompt engineering and LLM application architecture.
Lead red-teaming exercises and improve robustness against adversarial inputs.
Track latency, cost, and quality trade-offs in LLM application design and recommend optimizations.
Document patterns, anti-patterns, and lessons learned for internal reuse.
Stay current with LLM capabilities, tooling, and research, and translate advances into practical guidance.
