TaxValet is seeking an AI Engineer II to lead the design, development, and ownership of AI-powered internal platforms and systems. In this remote role, you will take on end-to-end ownership of complex projects, from problem discovery to production rollout, translating ambiguous business problems into scalable, AI-enabled solutions.
What You'll Do
- Lead the design, development, and ownership of AI-powered internal platforms and systems, including initiatives built from the ground up.
- Own end-to-end delivery of complex projects, from problem discovery and system design through production rollout and iteration.
- Design and implement AI-driven features, intelligent automation, and orchestration systems that enhance customer experiences and compound productivity across teams.
- Embed AI capabilities into customer-facing products, internal tools, and operational workflows, ensuring solutions integrate naturally and deliver measurable value.
- Build full-stack systems spanning backend services, APIs, data layers, and frontend interfaces.
- Translate ambiguous business and operational problems into scalable, maintainable, AI-enabled technical solutions.
- Apply strong systems thinking to ensure reliability, performance, security, permissions, and auditability across platforms.
- Collaborate closely with engineers, teams, and stakeholders across the company to identify high-impact opportunities and drive adoption.
- Participate in production support and incident response for owned systems, helping define and uphold reliability and operational best practices.
- Mentor AI team members through code reviews, design feedback, and hands-on guidance, raising the overall quality bar of the team.
What We're Looking For
- 3–5 years of professional experience in software engineering, AI engineering, platform engineering, or related roles.
- Hands-on experience designing, building, and shipping AI-powered systems into production environments.
- Strong proficiency in Python, SQL, and frontend frameworks such as React.
- Proven experience designing and owning production-grade full-stack systems.
- Experience working with distributed systems, internal platforms, or complex data workflows.
- Ability to operate effectively in ambiguous problem spaces and drive solutions with minimal direction.
Nice to Have
- Experience building AI-first platforms or internal products from scratch, including early architectural decisions.
- Strong foundation in core machine learning and data science principles, including supervised/unsupervised learning, feature engineering, model evaluation, and statistical inference.
- Experience with transformer architectures (BERT, GPT, etc.) and understanding of attention mechanisms, tokenization, and fine-tuning strategies for domain-specific applications.
- Experience developing AI-assisted or agentic systems that interact with tools, data, or workflows.
- Familiarity with embeddings and vector representations, including text embeddings, similarity search, and integration with vector databases (Pinecone, Weaviate, pgvector, or similar).
- Experience with NLP techniques including text classification, named entity recognition, semantic search, and information extraction.
- Familiarity with cloud-native development using AWS.
- Understanding of prompt engineering, retrieval-augmented generation (RAG), and LLM application patterns.
- Experience with containerized systems and orchestration tools such as Docker and Kubernetes.
- Exposure to CI/CD pipelines and modern development workflows (e.g., GitLab).
- Experience with Golang is a plus (or willingness to learn).
