AI Engineer

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field. \n

• 2-3 years of experience in software engineering using one or more programming languages: Python, Java, Node.js, C#, or similar. \n

• 1-2 years of hands-on experience building with LLMs-prompt engineering, RAG, agents, tool/function calling, structured outputs, and streaming. \n

• Proficiency with LLM SDKs and frameworks (e.g., OpenAI/Azure OpenAI, Anthropic, Google, LangChain, LlamaIndex) and vector databases (e.g., Pinecone, Weaviate, pgvector/Postgres, FAISS). \n

• Experience preparing unstructured data (PDFs, HTML, emails, tickets) and developing robust ingestion/embedding pipelines and document stores (e.g., S3, GCS). \n

• Familiarity with evaluation and observability tools (e.g., LangSmith, RAGAS/DeepEval, OpenTelemetry, logging) and experience writing automated tests for LLM workflows. \n

• Basic DevOps/MLOps skills: Docker, Kubernetes or serverless (Lambda, Cloud Run), CI/CD (GitHub Actions), and secrets/IAM best practices. \n

• Exposure to cloud platforms (AWS, Azure, GCP) and related services (API Gateways, managed databases/queues; Bedrock or Azure OpenAI experience is a plus). \n

• Strong problem-solving and communication skills; ability to translate business workflows into practical automations and clearly explain trade-offs to non-technical stakeholders. \n, * Experience with fine-tuning or LoRA adapters for domain-specific tasks; knowledge of prompt caching and cost optimization strategies. \n

• Experience integrating with enterprise applications and knowledge bases, and developing lightweight admin UIs (React, Next.js) for internal tools. \n

• Strong security mindset, including familiarity with OAuth/JWT, least-privilege access, PII handling, and compliance best practices

Our teams work hands-on with clients to automate complex processes across a range of systems, from modern applications to legacy environments. A significant portion of our work is within the public sector, where we help government organizations streamline high-volume processes, improve data quality, and modernize critical operations through automation.

What You’ll Be Doing

\n \n

• Build LLM-powered automations, chat/voice assistants, and intelligent agents that integrate seamlessly with client systems. \n

• Design and deploy retrieval-augmented generation (RAG) pipelines, including document ingestion, chunking, embeddings, vector search, and grounding for accurate, auditable responses. \n

• Implement tool/function calling and multi-step agent workflows to perform actions (draft * review * execute * verify), incorporating human-in-the-loop processes where necessary. \n

• Package solutions as reliable services (e.g., FastAPI or Node.js) with tests, observability, and CI/CD pipelines; deploy to the cloud using serverless or containerized architectures. \n

• Instrument, evaluate, and tune LLM solutions-manage tracing, latency and cost budgets, prompt/version control, A/B tests, and golden-set evaluations to reduce hallucinations and improve output quality. \n

• Implement guardrails and safety mechanisms, including content filters, PII redaction, schema/JSON validation, fallbacks, and model routing across providers. \n

• Collaborate with product, delivery, and client stakeholders to scope use cases, run quick proofs of concept (POCs), and scale successful prototypes into production-ready systems. \n

• Participate in code reviews and contribute to improving internal templates, tooling, and documentation to enhance reliability and development speed. \n

• Occasionally support hiring initiatives through interviews or technical assessments. \n
