At Fireworks, we’re building the future of generative AI infrastructure. Our platform delivers the highest-quality models with the
fastest and most scalable inference in the industry. We’ve been independently benchmarked as the leader in LLM inference speed and
are driving cutting-edge innovation through projects like our own function calling and multimodal models. Fireworks is a Series C
company valued at $4 billion and backed by top investors including Benchmark, Sequoia, Lightspeed, Index, and Evantic. We’re an
ambitious, collaborative team of builders, founded by veterans of Meta PyTorch and Google Vertex AI.
In the last few months alone we launched Fireworks Training, partnered with Microsoft Azure Foundry, and published research
straight from our production systems. A few examples of what that looks like in practice:

The Role
AI Field Engineers at Fireworks are the technical tip of the spear. You embed with our most ambitious customers and technology
partners to turn complex AI problems into production systems, fast. The role sits at the intersection of engineering, product, and
customer delivery. You are hands-on-keyboard building POCs, MVPs, and production integrations, while also holding your own in
executive-level conversations about architecture, strategy, and business outcomes.
You spend most of your time building. You ship code, run benchmarks, debug production issues, and architect deployments. But you
also lead discovery conversations, align stakeholders, and translate customer pain points into product improvements that compress
the feedback loop from field to roadmap. This is a role for engineers who are comfortable on-site with customers, building the
relationships and trust that happen in person, not just over a call.
The Segment
As a Field Engineer in the Enterprise track you will work with large organizations and digital-native companies adopting GenAI
across the business. These engagements span more stakeholders and longer cycles, so you will manage executive relationships and
align teams while staying hands-on in the code. The emphasis is on pairing strong technical delivery with the executive presence
to earn trust across an org: discovery, solution design, POC execution, and the path to production at enterprise scale.

Please note: This is a 12-month contract Location: London, UK (Hybrid position, in office 2 days per week) With millions of diners, 60,000+ restaurant partners and 25+ years of experience, OpenTable, part of Booking Holdings, Inc. (NASDAQ: BKNG), is an industry leader with a passion for helping restaurants thrive. Our world-class technology empowers restaurants to focus on what matters most – their team, their guests, and their bottom line – while enabling diners to discover and book the perfect restaurant for every occasion. Every employee at OpenTable has a tangible impact on what we do and how we do it. You’ll also be part of a global team and its portfolio of metasearch brands. Hospitality is all about taking care of others, and it defines our culture. The Position We're looking for a growth marketer who's restless, someone who runs projects at scale by obsessively removing the manual steps holding them back, and who reaches for AI the same way others reach for a spreadsheet. This is a systems-first marketing role. You'll own process optimisation and growth systems for the International Marketing team, identifying where work is manual, repetitive, or slow, and building the automations and AI-powered workflows to fix it. You'll work closely with engineering to scope and ship tooling that makes the whole team more effective. You'll also run a portfolio of growth campaigns, so you need to be both a builder and an executor. But your defining contribution will be making the team faster and smarter, not just delivering your own output. You'll be the connective tissue between channel owners, market owners, and engineering, the person who figures out how to do more with less. If you've ever built a workflow just because something was annoying you, that's exactly the mentality we're hiring for. What You’ll Do * Identify and map the international marketing team's growth workflows end-to-end; identify manual steps that are candidates for automation, AI-assisted tooling, or smarter process design. * Scope and build AI-powered marketing workflows in partnership with engineering: briefing tools, content generation pipelines, performance monitoring bots, and more. * Write clear specs that translate marketing requirements into engineering stories: you don't need to code, but you need to think in systems and communicate technical requirements clearly. * Prototype, test, and iterate on new tooling before handing it off or scaling it across the team. * Educate and enable the team on new tools and workflows: run training sessions, write documentation, build internal champions. * Own a portfolio of growth campaigns end-to-end across multiple international markets: brief, execute, measure, iterate, scale. * Identify new growth opportunities: new channels, audience segments, mechanics that go beyond the existing playbook. That includes upper-funnel channels like connected TV and out-of-home where the right moment calls for it, and knowing how to build the case and a plan for them. * Be the connective tissue between market owners, channel owners, and engineering; keep cross-functional work moving. What Makes You a Strong Fit * You've run growth projects end-to-end: identified an opportunity, built the business case, and driven it to an outcome, ideally across multiple markets or functions. * You think in systems: your first instinct when something is repetitive is to design a way to never do it manually again. * You've built something real with AI: an automated agent, a prompt system, or a custom integration that solved a real problem at work, not just experimented with chatbots. * You can work with engineers: you've collaborated with technical teams to build something, whether that's a data pipeline, an automated workflow, or a custom integration. * You can write a clear brief, a concise spec, and a stakeholder update, and know which one the situation calls for. * You have working knowledge across the growth marketing stack: paid, organic, CRM, content, and social. You don't need to be an expert in each, but you speak the language. * You understand how channels work across the full funnel, and can evaluate new media opportunities: when they're the right call, how to measure impact, and how to make the case internally. * You operate at scale: you know how to prioritise, delegate smartly, and use tools and systems to punch above your weight. * You're a fast learner who ships: you'd rather launch a good version and iterate than wait for perfect. * 6+ years in growth marketing, ideally in-house at a consumer tech brand or a fast-growing startup. * Native English fluency; additional language capability a plus. * Bachelor’s degree or equivalent experience in marketing or related fields. You’ll Thrive Here If * You love building systems, not just running them. * You find inefficiency genuinely irritating. * You default to “I’ll figure it out”. * You get energised by a blank brief. * You enjoy working with both brand marketers and technical teams. * You obsess over iteration speed. * You enjoy working across cultures and markets. * You love restaurants and dining culture. BENEFITS AND PERKS * Work from (almost) anywhere for up to 20 days per year * Focus on mental health and well-being: * Company-paid therapy sessions through SpringHealth * Company-paid subscription to Headspace * Annual company-wide week off a year - the whole team fully recharges (and returns without a pile-up of work!) * Paid parental leave * 5 weeks paid vacation * Time off for your birthday * Paid volunteer time * Focus on your career growth: * Development Dollars * Leadership development * Access to thousands of on-demand e-learnings * Travel Discounts * Employee Resource Groups * Private health & dental insurance * Income protection and life assurance * Employee Assistance Program - including 24/7 GP & free legal advice * Pension plan contributions * Discounted gym membership * Bike2Work * Season ticket loan * Social events & Thursday happy hours * Free lunch 2 days per week Work Environment & Flexibility At OpenTable, we pride ourselves on fostering a global and dynamic work environment. As a team member with us, you will benefit from a schedule tailored to accommodate a global workforce operating across multiple time zones. While the majority of your responsibilities may align with conventional business hours, there will be instances where you are expected to manage communications - via calls, Slack messages, or emails - outside of regular working hours to effectively collaborate with international colleagues, respond to restaurant partners, and/or address urgent matters. OpenTable will always abide by and consider local laws and regulations. Inclusion We’re committed to creating a workplace where everyone feels they belong and can thrive. We know the best ideas come when we bring different voices to the table, so we're building a team as dynamic as the diners and restaurants we serve—and fostering a culture where everyone feels welcome to be themselves. If you need any reasonable adjustments during the application/interview process, or on the job, we’re here to support you. Please reach out to your recruiter to request any accommodations. #LI-Hybrid #LI-BR1
