Vailent is seeking a customer-facing engineer at the intersection of deployment, integration, and product. You will embed directly with chemicals distributors, polymer producers, and elastomer traders to build production solutions that make Vailent work in real environments.
The role requires moving fast, shipping production-quality code, and deriving patterns that become features for all customers. You will own the integration lifecycle and serve as the technical liaison throughout engagements.
Vailent is the AI infrastructure for the materials industry — chemicals, polymers, elastomers, rubber. The companies in this space run on a mess of CRMs, ERPs, point tools, and flat files. We're replacing all of that with one system that turns every interaction, transaction, and physical asset into usable commercial data.
Materials are the foundation of the physical economy: they're in everything. Every product humans build, ship, eat, wear, or drive starts here. But the industry is still massively under-instrumented, running on fragmented tools and the institutional knowledge of people who've been doing it for decades. At Vailent, we're building the infrastructure that will transform this industry for the next century, capturing multi-modal industry context across both software and hardware.
A customer-facing engineer who lives at the intersection of deployment, integration, and product. You'll embed directly with our customers — chemicals distributors, polymer producers, elastomer traders — understand their real operational environment, and build the production solutions that make Vailent work inside it. The job isn't demoing software; it's owning the outcome.
FDEs build the rough path that proves what's possible in a specific customer's environment. Core product engineers then generalize it. That means you need to move fast, ship production-quality code, and bring back what you learn — because the patterns you surface in the field become the features that ship to everyone.
Our customers run complex enterprise stacks: SAP/ERP systems, legacy CRMs, bespoke flat-file workflows built over decades. Integrating Vailent into that environment requires engineering depth and customer trust in equal measure. You'll be the person who earns both.
Hire for the disposition. The stack is learnable; this isn't.
These principles are non-negotiable, because at this volume they're what keep the work correct. If you don't already work this way, the throughput becomes a liability instead of an asset.
01 — Prove it in the real environment. "Done" means demonstrated, not asserted. A green badge over $0 / insufficient data is a failure. subrc=0 means nothing until the record reads back. The data wins, never the badge.
02 — Never guess. Verify what's knowable in the code; ask about what's a genuine product decision; assume nothing in between. Confident fiction is worse than an honest "I don't know yet."
03 — Diagnose before you touch. "Look into it" means read-only until told to fix — especially on anything live. Root cause and a proposed fix come first; the change waits for an explicit go. Production is sacred.
04 — Copy what works. If working examples already solve a problem, read the proven pattern and adapt it. Don't invent a fresh approach and burn an afternoon proving it wrong.
05 — Enhance in place, never fork. Generalize the existing path — add an optional parameter where today is the degenerate case — rather than shipping a parallel reimplementation. Design the capability; a single customer is the validating example, not the spec.
06 — Risk isn't size. Bigger isn't worse; riskier is. Risk is load-bearing code modified × silent-failure potential × blast radius. A large additive change can be safer than a one-line edit to a hot path.
07 — Build to scale — or name the debt. Ship the agreed slice now, but flag anything that won't scale as explicit, revisit-able debt. Hardcoded shortcuts are fine only when chosen out loud, never smuggled in.
08 — Own the correction. Verify findings adversarially — a second pass whose job is to refute the first. When the evidence turns, reverse yourself out loud. The best catches are corrections of your own confident conclusions.
09 — Words are a feature. Terminology has precise internal meaning. Inventing loose language for things that already have names is a real defect — caught and corrected on the spot, not waved through.
10 — Leave a trail. Every engagement ends with a handoff so the next person — human or agent — starts informed.
Specs, runbooks, tracked tickets, and durable notes are part of the deliverable, not overhead.
Frontend — React, TypeScript, Vite, TanStack Query, a token-based design system.
Backend — Python, FastAPI (async), SQLAlchemy, Alembic, Celery, Pydantic; an SNS®SQS event bus with idempotent dedup.
Data — PostgreSQL with row-level security, schema-per-app, JSONB + GIN/GIST, Neo4j (Cypher), pgvector.
Platform / Infra — AWS (ECS Fargate, Aurora, RDS Proxy, Route53, ACM, WAF, CloudFront, IAM/OIDC), Terraform, dual-account, per-branch Docker stacks.
Enterprise integration — SAP ECC via RFC/BAPI, ABAP, pyrfc, customer/order master data, additional ERP connectors, M2M auth.
Identity & AI — Auth0 (Organizations, M2M, custom claims), JWT entitlement gating; Claude Code agents, worktrees, skills, hooks, MCP.
Customer environment — Multi-tenant: five active tenants
