Role Description
gravity9 is expanding its Forward Deployed Engineering team to build production agentic AI systems for enterprise clients, in partnership with leading frontier-model providers. We already support clients from different verticals to have agentic and RAG systems live in production across healthcare, financial services, retail and global logistics.
As a Forward Deployed AI Engineer you work embedded in the client's environment, from discovery, through architecture and build, to production and handover. This is end-to-end agent engineering, not proofs of concept and not advisory work. Two flavours of engagement:
Internal enterprise use cases, such as reconciliation and KYC workflows in financial services, clinical and claims workflows in healthcare, operations and supply-chain workflows in logistics.
Product- and customer-facing agents, more greenfield, often exploratory, built into the client's own product.
Engagements are typically a team of engineers over a few months, working shoulder-to-shoulder with the client's team including architects, DevOps and QA.
Embed with the client. Work hand-in-hand inside the client's environment, codebase and cloud tenancy, often in a hybrid team alongside their engineers. You are visible to the client from day one.
Design and build production agentic AI systems. Multi-agent orchestration, tool and function calling, retrieval, planning and routing, human-in-the-loop checkpoints, state and checkpointing, guardrails, failure handling and recovery.
Do the unglamorous data work. A large share of every engagement is data engineering: ingestion, flattening deeply nested structures, extracting content from unstructured documents, classification, summarisation, tagging, enrichment, indexing. Models reason over data, bad data beats a good model every time.
Own evaluation and accuracy. Establish a baseline eval dataset at the start of the engagement, automate grading, and track groundedness, faithfulness and retrieval quality per tool, not just at the agent level. Be ready to defend accuracy numbers to a sceptical enterprise stakeholder.
Engineer for cost and latency. Model selection and routing (cheaper, faster models for non-reasoning steps; frontier models where reasoning genuinely earns it), prompt and context budgeting, caching. Cost is a non-negotiable metric on every engagement.
Ship it properly. Observability and tracing, CI/CD, IaC, monitoring the client can actually operate, security and compliance review.
Transfer knowledge deliberately. We don't run a long-term support business. Every engagement is designed so the client owns and can extend the system after we leave. You architect with their team in the room, pair with their engineers, and hand over working monitoring and documentation.
Technical skills
Essential
Programming: Strong Python (async, typing, testing, packaging). Working competence in TypeScript / Node is a plus.
LLM application engineering: Hands-on production experience with frontier models: prompt and context engineering, structured outputs, tool and function calling, streaming, token and context-window management.
Agentic architecture: Built and shipped multi-agent or agentic workflows, planner/router patterns, supervisor and sub-agent designs, ReAct-style loops, state and checkpointing, retries and interrupts, human-in-the-loop review gates.
Frameworks: At least one of: Anthropic Agent SDK, LangGraph, LlamaIndex, or an equivalent orchestration framework, plus the judgement to know when to use none of them.
RAG and retrieval: Chunking strategy, embeddings, hybrid and semantic search, re-ranking, citation and provenance, natural-language-to-query translation.
Data platforms: NoSQL databases such as MongoDB (aggregation pipelines, Atlas Search, Atlas Vector Search) or a strong equivalent, plus SQL. Comfortable designing schemas for agent retrieval, not just for OLTP.
Data engineering: Building ingestion and enrichment pipelines over messy structured and unstructured sources, documents, PDFs, object storage.
Evaluation: Building eval harnesses and eval datasets, LLM-as-judge with its limits understood, regression testing of prompts and agents, metric selection per use case.
Cloud: Production delivery on AWS (incl. Bedrock), Azure or GCP, containers, serverless, networking basics, secrets management, IAM.
Engineering discipline: Git, code review, testing, CI/CD, IaC (Terraform or equivalent), observability.
Strong advantage
Anthropic certification (Claude Developer / Anthropic-issued credential), an explicit advantage at shortlisting.
Anthropic Agent SDK production experience, a significant bonus.
MCP (Model Context Protocol): building servers and clients, tool exposure, auth patterns.
Claude Code as an autonomous SDLC agent: sub-agents, hooks, custom skills, agent marketplaces, context sharing across a team.
LLM observability and tracing tooling (LangFuse, LangSmith, Arize, Braintrust or similar).
Regulated-environment delivery: HIPAA, GDPR, SOC 2, FCA/PRA, PII handling, data residency, guardrails and red-teaming.
Graph or taxonomy-based knowledge representation alongside vector retrieval.
Kafka / streaming, Databricks, or comparable large-scale data platform experience.
Nice to have
Voice and multimodal agents; evaluation of non-text outputs.
FinOps for AI workloads; unit-economics modelling for agent systems.
Open-source contribution to the agent / LLM ecosystem, or conference speaking.
Prior experience as an FDE, solutions architect, or delivery consultant at a frontier-model, data platform, or infrastructure vendor.
Soft skills
An FDE is an engineer who is safe in front of a client. We screen as hard on this section as on the technical one.
Client presence and credibility. Can hold a technical conversation with a client architect and a business conversation with their CTO or head of operations in the same hour, and be trusted by both. Can present, whiteboard, and answer hard questions without deflecting.
Translation. Turns a business problem described by non-technical people such as a clinician, campaign manager or supply-chain planner into a technical design, and explains the technical design back in their language.
Ego-free collaboration in a supporting role. On some engagements the tech lead will come from the client or a partner, not from us. You need to contribute strongly, disagree well, and take direction without friction. Brilliant-but-territorial doesn't work here.
Comfort with ambiguity and greenfield. Engagements often start before the requirements, the data access, or sometimes the problem statement are settled. You make progress anyway, and you make the ambiguity visible rather than hiding it.
Bias to production. Instinctively asks "how does this get deployed, monitored and maintained?" rather than stopping at a working notebook.
Teaching instinct. Actively enjoys upskilling the client's engineers, because self-sufficiency at handover is the definition of success, not follow-on billing.
Ownership and pace. Short engagements, small teams, no layers to hide behind. You unblock yourself, chase the access request, and follow the thread to the answer.
Commercial awareness. Understands that scope, cost and the client's willingness to pay are part of the engineering problem, and contributes to scoping and estimating honestly.
Resilience and adaptability. New client, new domain, new stack every few months; occasional travel; occasionally a sceptical stakeholder who has been told AI is coming for their job. You stay steady and constructive.
Written communication. Clear design docs, decision records, handover material and status updates in English. Much of this is asynchronous and cross-timezone.
Genuine curiosity about the field. This ecosystem changes monthly. We want people who are already reading, building side projects and forming opinions — not waiting for training to be scheduled for them.
Experience profile
FDE (mid): 3+ years software engineering, 1+ years hands-on LLM / agentic work with at least one system live in production. Client-facing exposure.
Senior FDE: 5+ years engineering, 2+ years AI or agentic AI, has owned the architecture of at least one production agent system end-to-end and led a client conversation about it.
Lead FDE: 7+ years, has led delivery teams of 3–7 people, can act as engagement tech lead, contributes to pre-sales and estimation, and can mentor a growing FDE bench.
What success looks like
First 90 days — owning a meaningful component of a client-facing agent system, including its evals, and trusted in front of the client.
6 months — designing agent architectures independently, leading a workstream, and running the handover and knowledge-transfer track.
12 months — a reference point for others on the team, contributing to reusable assets, pre-sales and interviewing.
What we offer
Support for vendor certifications and access to partner training programmes.
Company-wide AI tooling as part of how we work day to day.
