About Us Oliv.AI is a SalesTech global startup headquartered in San Francisco, debuting the world's first team of AI Agents for sales. With our recent $5.2M Seed funding, we solve one of the biggest problems for revenue teams: unreliable deal data. Oliv captures Deal Intelligence from every meeting, call, and email—without any rep involvement. The result is a clear, detailed view of every deal, presented in scorecards built on trusted sales methodologies like MEDDICC, BANT, and SPICED. Our AI agents are built for sales teams—sales managers, AEs, and RevOps—handling the work that takes them away from selling. With Oliv AI, sales teams can bring back focus on deals, strategy and conversation. The role This is not a traditional marketing role, and it is not a pure engineering role either. You will decide which accounts matter, build the systems that research them, write the content that reaches them, build the partnerships that amplify it, and turn all of that into qualified pipeline. Two things have to be true about you at once. You are technically sharp enough to build your own workflows, wire up your own APIs, and ship a working system without waiting on engineering or anyone else. Nothing you own should be blocked on a single person, including us. And you are obsessed with distribution — content, syndication, social, and partnerships — because pipeline goes to whoever the buyer already trusts. That means newsletters, communities, podcasts, comparison pages, partner audiences, and the people who influence them. What you will own GTM strategy and experimentation Develop and continuously refine Oliv's ICP, market segments, buyer personas, and account-selection criteria. Translate company goals into specific growth hypotheses and campaign plans. Identify new audiences, buying signals, use cases, and distribution opportunities. Build a structured experimentation roadmap across content, social, syndication, partnerships, outbound, and ABM. Define success metric

As a Field Engineer on our federal AI projects, you'll work directly with our largest public sector customers to make sure their experience with Scale's technology is smooth and successful. You'll help these customers build production-grade data pipelines, working closely with our Product, Engineering, and Operations teams. This means learning each customer's use cases in depth and building the tools and documentation they need to grow. The role sits at the intersection of customer delivery, product, and engineering. The ideal candidate is a generalist software engineer who enjoys working with clients, takes ambiguous problems and turns them into practical solutions, and collaborates closely with Product and Engineering along the way. An active TS/SCI clearance is required. What You'll Do Build end-to-end data integrations that sync customer data to and from Scale's platform Work with customers' engineering teams to optimize data pipelines, including input on API endpoint design and input/output schemas Design and maintain playbooks, internal tools, documentation, and SDKs that set customers up for long-term success Partner with engineers and Operations to resolve technical blockers, debug delivery issues, and own technical escalations from customers Own the customer's technical experience throughout their time with Scale Work with Account Executives and Product Managers to identify customer-specific feature requests Develop expertise in large language models, 2D image annotation, and API integrations Represent Scale and engage with customers at major events What We're Looking For Experience as a customer-facing engineer or in a similar hybrid role Hands-on technical experience working with clients in a pre- or post-sales capacity Development experience with Python, JavaScript, or other modern languages A strong engineering background, ideally in computer science, mathematics, or another quantitative field Strong project management and interpersonal skills The abili

Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code.

Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company. At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in. Available Locations: Austin, Texas About the role Created in January 2025, our centralized Developer Go-to-Market (GTM) organization functions as a "speedboat" to maintain focus, control direction, and iterate quickly. Our mission is to build long-term relationships with developers by addressing their unique needs and challenges with specialized attention and resources.

About Vercel: Vercel is the agentic infrastructure company, freeing people and agents to ship what's next. For more than a decade we've helped builders move from idea to production with speed, security, and exceptional developer experience. Now we're scaling our products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide. About the role: We're hiring a DevRel Engineer to work inside the product teams building Vercel's agentic infrastructure: AI Gateway , Sandbox , and the primitives that come after them. You'll sit with product and engineering, build with these tools before anyone else can, and show the world what they make possible. You will report to the Head of AI Infrastructure and can be located anywhere. If you’re based within a pre-determined commuting distance of one of our offices (SF, NY, London, or Berlin), the role includes in-office anchor days on Monday, Tuesday, and Friday, even if the role is listed as remote. For location-specific details, please connect with our recruiting team. When applying, include a link to something you made that taught developers something, a talk, a repo, a post, a video. Applications without one will not be considered. What you will do: Build agents and applications on AI Gateway and Sandbox before they ship, then turn what you learn into demos, templates, and open source projects developers actually clone and run. Teach developers how to build with agentic infrastructure through writing, talks, videos, and live coding. You set the canonical examples the ecosystem emulates. Shape the products themselves. You sit in the same planning meetings as the PMs and engineers, and your job is to hit the rough edges first and make sure they get fixed before launch. Own the important pieces of launches: example repos, launch demos, docs contributions, and the first wave of answers when developers start asking questions. Bring the outs
