BrandMultiplier | Head of AI & Engineering | REMOTE | Fractional-to-Full-Time | Equity

We're a profitable B2B services company ($3M–$50M ARR clients) actively building a proprietary AI platform — and we need the technical leader to own the execution.

WHAT WE'RE BUILDING: A multi-agent AI platform that operationalizes our founder-story methodology into deployable client systems. Architecture spec exists, pieces are already in production. We're not starting from scratch — we're scaling a real build.

THE STACK: LLMs (Claude, GPT, Gemini), multi-agent orchestration (LangGraph/LangChain), RAG pipelines, vector databases, React/Next.js, Python/Node.js, AWS, n8n/Make for automation.

WHAT MATTERS MOST: You're not just an executor. You come to the leadership table with tools and approaches we haven't seen yet. You translate the CEO's vision into a technical spec, a build plan, and a shipped product — without needing everything pre-defined.

THE TEAM: 4 core people. You'd join the CEO, a Growth Strategist, and an Operations Manager — and lead one AI Engineer (your first direct report).

ENGAGEMENT: Starts fractional with a clear path to full-time and equity for the right fit. We're not VC-funded by design, so equity is unencumbered.

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Full-Stack Engineer (Python / React) , Remote

We’re working on building production AI systems , not demos ,focused on real-world workflows, data pipelines, and integrating LLM-based systems into usable products.

Stack: - Python (FastAPI) - React / TypeScript - AWS / PostgreSQL

Work includes: - designing backend systems and APIs - building and scaling LLM workflows (agents, pipelines, RAG) - handling real-world issues like latency, reliability, and hallucination control - integrating AI into product experiences end-to-end

Looking for engineers who: - have built production systems (not just prototypes) - are strong on backend design and data flow - have experience with AI/LLM systems in real use cases

Trustle | Customer Success Engineer | Remote (US) | Full-time | Pre-Series A

We enforce Zero Standing Privileges across cloud and SaaS — AWS, GCP, Azure, Snowflake, Okta, GitHub, and more. Access is requested just-in-time and disappears when the job is done. We are a small team and AI is core to how we work.

This role sits between customers, the CEO, and engineering. You'll build real multi-cloud demo environments (not toy setups), run technical sales conversations, own customer onboarding, and create technical content grounded in actual depth. When you find a product problem, you'll file it and often see it fixed the same week.

You should have: Comfort scripting and hitting APIs to automate your own work Basic cloud familiarity (AWS, GCP, or Azure) — you know what a role and a service account are

Experience in customer-facing technical conversations A habit of publishing: blog, GitHub, videos, etc

Bonus: IAM/cloud security background, experience with agentic AI/LLM workflows, GCP stack (GKE, Cloud SQL, Cloud Run)

Pre-Series A means your work directly shapes product and GTM. Cloud access management is one of the fastest-growing problems in security — this is a good place to build expertise at the center of it. Interested? Contact us careers (at) trustle.com | https://trustle.com

Temper | Founding Engineer | SF (In-Person) | $150K–$250K + Equity | https://ontemper.com Every time two companies in the physical economy need to exchange data, someone builds a custom integration by hand. Analysts, engineers, QA. All manual. Every time. Google "EDI" if you haven't. It's wild.

We built AI agents that do the whole thing: gather requirements in plain English, write the integration code, test it, deploy it, fix it when it breaks.

We have paying enterprise customers and more demand than we can keep up with.

You'd be the first engineering hire. Agent orchestration, durable execution runtime, self-healing infra, most of the important architectural decisions haven't been made yet.

The founders built a logistics startup from pre-seed to 400+ people. We've been dealing with broken integrations for years.
