Full Job Description

📋 Description

  • As a Software Engineer - AI at Promise Holdings, Inc., you will be at the forefront of transforming how government agencies and utilities support individuals facing financial difficulties. Your primary focus will be on designing, developing, and deploying end-to-end generative AI and Large Language Model (LLM) applications that are integral to our mission of making public systems simpler, faster, and more human-centered.
  • You will architect and build robust AI pipelines and infrastructure. This includes developing sophisticated systems for prompt engineering, enabling precise and effective communication with AI models. You will also implement fine-tuning processes to adapt models for specific use cases, create efficient document parsing mechanisms to extract and process relevant information, and build Retrieval-Augmented Generation (RAG) systems to enhance AI responses with external knowledge.
  • A key aspect of your role will be to guide new AI capabilities from their nascent conceptual stages through to successful real-world deployment. This involves a deep understanding of the AI lifecycle and the ability to translate complex technical concepts into tangible, impactful products.
  • You will be instrumental in developing AI products that cater to a diverse range of complex customer use cases. This requires adaptability and a strong capacity to understand and address the unique challenges faced by government agencies and utilities in serving their constituents.
  • The role demands comfort operating in ambiguous environments, where clear paths may not always exist. You will need to exercise strong technical judgment to prioritize development efforts, deciding what to build immediately versus what to scale for future growth and optimization.
  • Your contributions will directly drive innovation, enhance automation, and significantly improve efficiency across the Promise platform. By leveraging AI, you will help government services reach people more effectively, ensuring that assistance is delivered with greater dignity and accessibility.
  • This position offers a unique opportunity to be on the cutting edge of applied AI. You will shape systems that not only push the boundaries of artificial intelligence but also deliver substantial, measurable impact on a large scale, directly benefiting vulnerable populations.
  • You will collaborate closely with cross-functional teams, including product managers, designers, and other engineers, to identify and implement AI-driven solutions that reduce friction points, boost operational efficiency, and solve critical real-world challenges faced by our clients and their users.
  • A significant part of your responsibility will involve staying abreast of the rapidly evolving AI landscape. You will continuously track emerging trends, research new techniques, and apply advancements in AI and machine learning to guide our technical strategy and adoption of new technologies.
  • You will play a crucial role in shaping the future of AI/ML development at Promise. As an individual contributor, you will have meaningful ownership over technical decisions, contributing to the overall vision, strategic goals, and development roadmap for AI initiatives within the company.
  • You will be expected to take AI-powered products or major features from their initial conception (0→1) through to successful launch and iteration, demonstrating a full product development lifecycle ownership.
  • Experience in early-stage or high-growth environments is highly valued, as you will contribute to building and scaling innovative solutions in a dynamic setting.
  • You will have the opportunity to work on systems that are designed to be resilient and scalable, capable of handling the demands of government and utility sectors.
  • The role encourages a proactive approach to problem-solving, taking ownership of challenges and driving them to resolution with a focus on impactful outcomes.
  • You will contribute to a culture that values clear, candid, and constructive communication, fostering an environment of collaboration and continuous improvement.
  • Your work will directly contribute to Promise's mission of transforming public systems to work better for everyone, particularly for those most in need, by leveraging cutting-edge AI technology.
