How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

Location: New York HQ Workplace: OnSite ABOUT AVOCA Avoca is transforming how home service companies engage with their customers. Our AI-powered conversational agents handle every high-value inbound call, from booking jobs, qualifying leads, and driving higher revenue, all at a speed and consistency unmatched by human call centers. We're a Series B startup backed by Kleiner Perkins, Meritech Capital, General Catalyst, and other top-tier investors, with $125M raised and a $1B valuation. We grew 10x in 2025 and have scaled to 170+ employees in under two years across our NYC headquarters and Santa Barbara office. In a $1T+ market where 85% of missed calls go to competitors, we're building the category-defining platform for AI-driven customer engagement, serving the largest brands in home services. With high-energy, in-office teams in both locations, every hire here has an immediate and visible impact. ABOUT THE ROLE As a Field Engineer on the Pre-Sales team, you'll be the technical builder behind how we win and enable deals. You'll own two things: the integration work that proves technical feasibility to prospects and partners during the sales cycle, and the demo tooling that lets the entire go-to-market team tell a credible, product-accurate story. You'll work at the intersection of Sales, Partnerships, Product, Engineering, and AI, partnering with Account Executives and the Partnerships team as their technical counterpart. Unlike our Sales Engineers, who lead the customer-facing technical narrative, this role goes a layer deeper on the build: you're the person who can actually stand up a working integration against an unfamiliar API and turn it into a repeatable demo asset. This is a pre-sales role: you won't carry a closing quota, but your work directly determines whether technical buyers and integration partners trust that Avoca does what we say it does. WHAT YOU’LL DO - Own technical scoping and feasibility for pre-sales opportunities and partner integrations; turning ambiguous requirements from prospects, partners, and AEs into concrete, working implementation plans. - Build working integrations against third-party APIs, CRMs, field service management (FSM) platforms, telephony systems, and partner ecosystems, writing real code, handling REST APIs, JSON, authentication, and webhooks, and getting a credible proof of concept working quickly. - Build and maintain the demo and sandbox tooling the GTM org relies on: reusable demo environments, representative fixture data, and internal tools, treating one-off deal builds as reusable assets (integration patterns, reference implementations, scripts) rather than throwaway work. - Configure and tune Avoca's conversational AI for demo and POC scenarios, including prompt engineering to reflect real customer workflows. - Serve as the technical counterpart to Account Executives and Partnerships in the room with a prospect's or partner's engineering team, establishing credibility from the C-suite to individual developers, and translating those conversations into plans a non-technical AE can run with. - Troubleshoot and resolve technical issues that surface during evaluations, pilots, and POCs, protecting at-risk deals and partner launches. - Partner with Product and Engineering to feed recurring integration gaps and field learnings back into the roadmap, and to keep demo environments current as the product evolves. - Partner with (not replace) Forward Deployed Engineering and Implementation when a build needs to graduate from a working POC to a hardened production deployment: you own the pre-sales build and the demo layer; production delivery is a handoff. WHAT YOU'LL BRING - 4+ years in a technical, customer-facing role: Solutions/Sales Engineering, Forward Deployed / Deployment Engineering, Implementation or Integration Engineering, Solutions Consulting, or software engineering with meaningful customer exposure. - Hands-on ability to build. Proficient in TypeScript/JavaScript (Next.js, React, Node/Fastify); ships production-grade code and independently stand up an integration or demo tool, not just spec one for someone else to build. You don't need to be a production backend engineer, but "can build it yourself" is the bar. - Practical experience integrating against third-party APIs and enterprise systems: REST, JSON, authentication/OAuth, webhooks, and comfort working from unfamiliar or incomplete API documentation. - Working SQL and a solid grasp of relational data: enough to model, transform, and wire up realistic data for integrations and demo environments. - Experience owning something technical end-to-end, from requirements through build, testing, and a working rollout, even if handed off afterward. - Strong technical judgment and troubleshooting instincts, and the ability to explain complex technical concepts clearly to both technical and non-technical audiences. - A product mindset toward internal tooling: you treat demo and sandbox infrastructure as a product with users (the GTM team). - Familiarity with AI-powered products, conversational AI platforms, or data-driven systems. Bonus: prompt engineering, call center / communications platforms, CRM or FSM integrations, or prior Partnerships/channel support experience. WHO YOU ARE - Self-motivated, entrepreneurial, and comfortable operating in fast-moving, high-growth environments. - A builder who thrives on owning things end-to-end and turning one-off work into something reusable. - Autonomous, self-directed, and comfortable with ambiguity and incomplete requirements. - A proactive, effective communicator who's equally credible with a customer's engineers and your own AEs. - In-office, engaged, and eager to collaborate at our NYC location full-time. BENEFITS - Comprehensive medical, dental, and vision insurance - Company-sponsored 401(k) through Vestwell - Flexible PTO plus U.S. federal holidays - Company-wide off-sites - Daily in-office lunch through Parkday - Monthly wellness stipend - Dinner covered when working late - Commuter benefits and late-night rideshare - Standing desks and workspace accommodations available on request - All core tools and software provided Compensation: The expected base salary for this role is $160,000-$200,000 with final compensation based on experience, skills, and qualifications determined during the interview process. Avoca’s total compensation package includes base salary, bonus, equity, and a comprehensive suite of benefits and perks. Our Recruiting team will share the full details as you progress through our hiring process. WHY AVOCA At Avoca, you’ll be part of a team that’s building a category-defining company at the center of a massive market opportunity.
