## Job description

## About AZX

Our mission is to accelerate positive impact in critical industries through AI transformation. We specialize in physics-informed ML and enterprise AI solutions that directly address climate and sustainability challenges. We’re growing quickly and already work with category-leaders in real estate (CBRE), energy (LevelTen Energy), logistics (Flexe) and utilities. We bootstrapped profitably for our first year and are now backed by leading investors focused on AI, climate and energy. We work on challenges in clean energy, decarbonization, climate risk, energy systems, and global economics. We’re building our company for long-term success and aim to create the ultimate place to work for those passionate about AI and making a positive impact.

About This Role: We are seeking a Product Engineer that owns the demo's we build for clients from the schema to the pixel, the deployment and the observability. You'll work across the chat surface and agent workspaces, the app builder alongside the platform team, and the shared component and design system, plus the agent-facing developer experience — since our platform's users are coding agents as much as humans. Enterprise readiness is a feature here, not an afterthought: accessibility, localization, and audit trails get demoed, not promised. You'll build on the backend team's services and the runtime team's infrastructure, so overlap down the stack is expected.

Responsibilities:

- Build and evolve the chat surface and agent workspaces — streaming protocol on both client and server, message/run persistence, tool-call and approval UX, and citation rendering.
- Partner with the platform team on the app builder: the fixed app template and toolchain it generates against, the preview sandbox seam, and the generation/repair loop UX.
- Maintain the component and design system across chat, workspaces, and the app builder, keeping all three visually and behaviorally consistent.
- Build the agent-facing developer experience — CLI, deploy tooling, manifests — treating coding agents as first-class platform users alongside humans.
- Own the full stack behind your own features: TypeScript front end, Node/FastAPI backend-for-frontend, Postgres schema, deployment, and on-call.
- Ship enterprise readiness as a first-class feature — accessibility, localization, and audit trails — demoed working, not described as roadmap.
- Work down the stack when it matters: read backend service traces and runtime/Kubernetes logs to debug across the seam between product, backend, and platform teams.

Core Qualifications:

- 5+ years of deep, production experience with React/TypeScript — streaming UIs, high-frequency updates, virtualization, and real state management, with informed, hands-on opinions about React 19.
- Hands-on experience with a streaming protocol end to end (SSE or WebSocket) — chunk boundaries, reconnection semantics, abort propagation — including having personally debugged a raw byte stream.
- True full-stack ownership: you've shipped the backend half of your own front ends (Node/Fastify or Python/FastAPI), handling auth, idempotency, pagination, race conditions, and migrations.
- Product taste backed by enterprise experience — accessibility you can defend to a screen-reader user, thoughtful empty/error states, and localization that goes beyond a strings file.
- An AI-native working style: daily use of AI coding tools, driven by specs rather than vibes, with concrete examples of where you overrode a tool's output.
- A strong sense of ownership — instrumentation, evals on AI-dependent behavior, cost awareness, and on-call are part of "done," not a later phase.
- Practical depth in some of our core stack — TypeScript (strict), React 19, TanStack Query, Vite, Node/Fastify or Python/FastAPI, Postgres/Redis, and SSE/WebSocket streaming — with a track record of researching into unfamiliar parts of it.
- Familiarity with the surrounding toolchain: zod-validated wire contracts, sandboxed iframes/CSP/postMessage, Playwright/Vitest, WCAG 2.2 AA, i18n frameworks, and OIDC/OAuth2 session mechanics
- Bachelor's Degree; Master's is a plus

Why AZX!

- Be part of a fast-growing, profitable, mission-driven company with industry-leading clients tackling the massive opportunity of AI transformation in critical industries.
- Competitive early-stage startup compensation (based on capabilities, experience, and location)
- Bonus eligibility
- Health insurance with meaningful coverage for dependents
- Flexible paid time off
- Equity
- Fully remote culture with a cluster of teammates in Seattle

Additional Information:

- Must be able to travel 2x/year for company summits
- Applicants must be currently authorized to work in the United States on a full-time basis.
- We are unable to sponsor or take over sponsorship of employment visas at this time.
- Please note that our interview process includes a written take-home assignment followed by a live two-hour technical session with our engineering team, so if that format isn't a good fit, we'd ask that you not apply
- Please only apply to a maximum of 2 roles at a time, any applicants who apply to more then 2 roles within a 6 month period will automatically be disqualified

Next Steps: If this job sounds like a great fit but you don’t check ALL of these qualification boxes, we’d still love to hear from you!

- **Founded**: 2024
- **Founders**: Aaron Goldfeder (CEO), Richard Evans (Chief Technologist), Michael Albrecht

## Core Business
- **Primary industry/industries**: AI Transformation for Critical Infrastructure (Energy, Utilities, Real Estate, Logistics)
- **Target customers**: B2B, Enterprise, and Mid-Market (category leaders in regulated and complex industries like power utilities, commercial real estate, and logistics)
- **Mission or purpose statement**: To accelerate positive impact in critical industries through AI transformation. The company is structured as a Public Benefit Corporation (PBC).

## Products & Services
- **AZX Platform (Vertical AI for Critical Infrastructure)**: A growing platform of reusable data, code, and models built from client engagements. It focuses on solving messy, unstructured data problems and brittle workflows that off-the-shelf tools fail to fix. The model is a hybrid of high-touch strategy consulting and custom engineering, with reusable components that compound over time.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total Funding — **$6 million** pre-Seed round (announced in 2025/2026). Revenue is reported to be **up 10x** since the prior year.
- **Notable Investors/Partners**:
    - **Investors**: AI2 Incubator, Ascend.vc, SFV, Founders' Co-op, Kompas, Powerhouse Ventures, Stepchange Ventures.
    - **Clients/Partners**: Puget Sound Energy, CBRE, Franklin Energy, Flexe, Trilliant.

    - LinkedIn followers: 656 (monthly growth of +10.8%).

## Competitive Advantages
- **Vertical Focus**: Deep domain expertise in energy, utilities, and real estate, differentiating from horizontal SaaS platforms like Palantir (which are often too expensive for mid-market) and large integrators like Accenture.
- **Hybrid Model**: Combines high-touch, forward-deployed strategy and engineering with a reusable platform, creating a compounding moat that makes each engagement faster and more valuable.
- **Founding Team**: Founders are seasoned entrepreneurs with prior exits (EnergySavvy acquired by Uplight; Meetingflow acquired in 2024) and deep ties to the energy industry.
- **Public Benefit Corporation**: Mission-driven structure attracts talent and clients aligned with climate and sustainability goals.

## Strategic Focus
- **Scale the team**: Aggressively hiring to double headcount (targeting ~40 people).
- **Platform acceleration**: Extracting reusable capabilities from client work to shorten future deployment cycles.
- **Deepen client relationships**: Expanding within existing accounts (Puget Sound Energy, CBRE) and acquiring new category leaders in critical infrastructure.
- **GTM expansion**: Hiring a Director/VP of GTM and Client Engagement Managers to formalize sales motions.

## Why Work Here
- **Culture**: Described as high-EQ, low-drama, positive impact, fun, and flexible. The team is small (~20 people) and mission-driven.
- **Remote/Hybrid**: Fully remote culture with a cluster of colleagues in Seattle. Twice-yearly immersive in-person summits.
- **Benefits**: Competitive base + bonus, healthcare with meaningful dependent coverage and HSA, flexible time off, stock equity, 401k. The company emphasizes that if you are driven by perks, you might be happier at big tech, but if you are motivated by impact and upside, this is a strong fit.
- **Engineering Culture**: Focus on "code over PowerPoint" and solving real-world problems. Roles include Senior Full Stack Engineer, Senior ML Engineer, and GTM AI Engineer.
