The role Fibr is building the agentic web experience layer - turning every URL into an intelligent agent that senses intent, makes decisions, and adapts in real time. Our agents personalise the full journey, running long LLM workflows against live customer accounts and millions of sessions.
You'll own features end-to-end - from the rough idea in a Slack thread to something shipped, instrumented, and behaving correctly in production. New surface areas land on your plate every few weeks: a new agent, a new integration, a new optimization loop. You're responsible for the whole thing, including the evals and metrics that prove it works. You'll work directly with the founding team and ship to real users every week.
What you'll do Ship AI-powered features end-to-end - backend, data, LLM layer, and the surface the user sees Design long-running workflows that hold up against rate limits, partial failures, and noisy third-party APIs Build and maintain the evals, guardrails, and instrumentation that decide whether a feature is good enough to ship Model the data behind agents and the analytics behind product decisions Sit in on architecture calls and shape where the platform goes next
Must-haves 2-6 years of production backend experience Has shipped LLM-powered features to real users in production - not demos, not side projects. Be ready to talk about what broke and how you fixed it Has built and run evals for LLM systems. Show us the harness, the dataset, and the decisions it drove Comfortable across relational and document databases Has worked with a durable workflow or queue system in production Ships fast without breaking the build Nice-to-haves RAG, vector stores, or tool-use / multi-step agents in production Experience with rate-limited third-party APIs at scale (ad platforms, CRMs, analytics) Strong product sense - you catch the UX issue before the user does Time spent at an early-stage startup
How we work High ownership, low bureaucracy. Decisions in the room, not in docs. You'll work directly with the founding team.
Why Fibr AI Competitive salary + meaningful early-stage equity A chance to build deep expertise at the frontier of AI product

Role & Responsibilities
Own the Client’s Outcome:
- Embed with enterprise customers – on-site and remotely – to understand their supply chain operations, data estate, and what success actually looks like for their business.
- Scope and design technical solutions for messy, real-world logistics problems – with a clear line to measurable impact: cost per delivery, SLA performance, empty kilometres.
- Own the full deployment lifecycle: architecture through go-live through steady-state. You’re accountable for the outcome, not just the code.
Build and Ship:
- Design, build, and maintain backend services in Node.js or Python that power routing, planning, and execution at enterprise scale.
- Build and own the integrations connecting Locus to client ERPs, TMS, WMS, and OMS platforms – these integrations are often the riskiest part of a deployment.
- Write production code that runs under real load. If it isn’t in production, it hasn’t shipped.
Be the Technical Interface with the Client:
- Run architecture reviews, lead integration workshops, and represent Locus in executive steering meetings. You need to be credible at every level of the client organisation.
- Bring field learnings back into the product and platform teams. Some of Locus’s best features started as a client workaround.
- Push back when a client request would compromise platform integrity – and propose a better alternative.
Show Up On-Site:
- Travel to client sites – domestic and international, up to ~30% of the time – for kick-offs, integration sprints, go-lives, and post-live reviews.
- Build the kind of relationship where the client’s ops lead calls you directly when something goes wrong at 2am, not a support ticket.
- Be comfortable wherever the work is: a warehouse floor, a logistics control tower, a C-suite boardroom.
Make the Next Deployment Easier:
- Document architecture decisions, integration patterns, and deployment playbooks – every engagement should make the next one faster.
- Work closely with Product, Customer Success, and Platform Engineering. Share what you’re seeing in the field; don’t wait to be asked.
- Mentor junior FDEs and raise the technical bar across the team.
