Forward Deployed Engineer - backend - python | REMOTE (Europe)
hn · REMOTE (Europe)
Jose is an exceptionally strong match: he has exactly the rare combination of senior backend engineering (12 years shipping production systems), direct LLM agents experience in production (Addie's LangGraph system, Rubercubic's agent work), and proven customer-facing ownership (founding engineer shipping to 10+ countries). His experience building real-time, multi-channel systems under operational constraints, combined with clear technical judgment and the ability to work alone as the sole engineer, directly mirrors the job's core requirements.
Hook: As a founding engineer who shipped LLM agents to production serving students globally while owning customer relationships and infrastructure, you have the rare blend of technical depth and customer-facing ownership this role demands.
Missing: Specific CRE domain knowledge, European jurisdiction experience, RBAC/auditing systems (though infrastructure background suggests quick ramp)

Kinxshn | Forward Deployed Engineer - backend - python | REMOTE (Europe) | Full time | Funded We build AI agents that run real operations. Humans talk to our agents to run commercial real estate: leases, contractors, invoicing, accounting. We're live in production across several European jurisdictions, with real customers and real money. We need a Forward Deployed Engineer to own a client-facing use case end to end: a strong backend engineer who is also the face of the team to the customer. The job: - Talk to clients directly and often. Pull requirements out of messy conversations, explain tradeoffs, own the relationship - Turn jurisdiction-specific lease rules, tax and accounting mappings, client-specific workflows into tools our agents call - Ship to production in your first month, then keep it alive What we need, in this order: 1. Self-driven, real ownership. You'll have a lot of freedom and support, but the use case is yours end to end - nobody will be feeding you tickets. 2. Excellent English and real customer-facing experience. You'll be on client calls every week. 3. Serious backend experience. You've shipped and operated production systems, and can work as the only engineer in the room. We use AI tools heavily, but we don't vibe code: your engineering judgment and review are what make the code shippable, and you own what you merge. 4. LLM agents in production, or you ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call. Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain/LangGraph, operator or consulting background. We're a small senior team across Europe and South America. For this role we need you in Europe. Competitive comp - we have no salary bands, for the right person we'll stretch.
