About Arbitr

Arbitr is the AI Context Platform. It understands a company’s context (its rules, approvals, strategy and markets) and deploys agents that act on it to the right standard.

We grew out of Straker, a publicly listed company with a long track record serving enterprise clients. We’ve rebuilt the business around AI and run it as a small team where every hire carries real weight. Things move fast here, and priorities change as we learn.

Arbitr and Cortex are our main product platforms. Under them, a rapid development team releases new products and features frequently, so launching well, again and again, is central to how we grow.

The role

You’ll build the engine that turns a new category into qualified pipeline. You’ll do it with a lean team (you and our Digital Marketing and Operations Coordinator) plus the agents you design, not by building a department.

Because we release new products often, a core part of the job is a repeatable go-to-market plan: a playbook you run for every launch, so each new product reaches the right buyers with the right message quickly, without starting from scratch.

This is hands-on. You write the copy, build the workflows, run the experiments and own the number. You’ll work directly with our Revenue Operations Lead and VP Sales.

How we work

Four principles you share with Revenue Operations

• Context first. Your ICP, messaging, offers and claims live in Arbitr, not in decks or spreadsheets. If it isn’t in the platform, your agents and Atlas can’t use it.
• Agents do the work; people approve what’s new. Your agents research, draft, personalize, publish and follow up inside rules you set. Any new message, offer or claim is approved by a person before it reaches a buyer.
• Figures are computed, never generated. Pipeline, attribution and cost per opportunity come from live data, using the definitions Revenue Operations sets. A model can explain a number; it never produces one.
• Small bets, fast cuts. Every experiment has a stop rule before it starts.

What you’ll own

• Qualified pipeline. You own the number and the agent-run engine behind it, for both new logos and expansion within our existing customers.
• Repeatable go-to-market. A launch playbook for new products and features under Arbitr and Cortex: positioning, target audience, channels, sales enablement and how each launch is measured. You run it every time and improve it each time.
• AI Visibility. You take over our AI Visibility campaigns and pilots, and make sure Arbitr shows up when buyers ask AI tools about our category.
• Messaging and content. You shape the category story with the CCO and CEO, then turn it into positioning, website copy and content that converts.
• Website, paid search, LinkedIn, email, social and content, run largely by agents you build and tune. Over time, you’ll test partner and marketplace channels that extend our reach without adding headcount.
• Existing customers. With Sales and our migration team, you run campaigns that introduce existing customers to new Arbitr and Cortex products as they launch.
• The buyer-signal loop. The objections, needs, questions and competitor names buyers raise on sales and migration calls each get an answer from you: a page, a piece of content, a sales asset or a change to messaging. As Atlas comes online, it surfaces these signals and routes them to you. You close the loop by telling Sales what shipped. Buyer needs that are product gaps go to Product.
• Many small tests with clear stop rules. Cut fast and scale what works.
• Your own tooling. Enrichment, sequencing and intent tools for the engine you run.
• Your coordinator. You lead our Digital Marketing and Operations Coordinator: setting priorities, reviewing the work and growing their skills, including how to work with agents.

Who you’ll work with

• You run the top of the funnel: campaigns, inbound, and outreach to new audiences. Account executives own named accounts and live deals. You and the VP Sales agree where the handoff sits.
• Revenue Operations. Our Revenue Operations Lead owns pipeline definitions, attribution and the forecast. You own what goes into the funnel. Definitions live in our platform, not in a team spreadsheet.
• Our product team is building Atlas, an intelligence layer on Arbitr that holds company context and directs agents across sales and marketing. Our Revenue Operations Lead owns it for the commercial team. You’ll be one of its first users and help shape what it does for growth.
• Weekly review. You bring experiments and results; RevOps brings the forecast and conversion data; the CCO decides.
• Investor relations. You work with our fractional investor relations lead so product launches, announcements and investor messaging tell the same story, timed with our disclosure obligations as a listed company.

Your first 90 days

* Days 1–30: learn and take over. Sit with sales, customers and product. Take over the AI Visibility campaigns already running. Audit the website, content and lead flow. Agree pipeline targets with the CCO.

* Days 31–60: launch. Get your agent-run engine live in at least two channels. Ship sharper messaging on the website and the first version of your launch playbook. Start your first experiments, each with a stop rule.

* Days 61–90: prove it. Report pipeline by channel against shared definitions. Run one launch end to end with the playbook, including existing customers. Cut what isn’t working. Present a plan for the next two quarters, including what your agents take on next and which partner or marketplace channels to test.

How we measure success

You’ll agree targets for each measure with the CCO in your first 30 days.

• Qualified pipeline created each quarter, new logo and expansion
• Coverage of next quarter’s new-logo target
• Cost per qualified opportunity
• Conversion from first touch to opportunity
• AI Visibility pilots signed
• Time from product release to live in market, and pipeline from each launch
• Buyer signals closed with an asset or a messaging change
• Share of campaign and channel work done by agents

About you

• 5–8 years in B2B marketing, mostly demand generation or growth at a SaaS, AI or tech company. You can show the pipeline numbers.
• You’ve done the work yourself recently. You’ve written the copy, built the campaigns and set up the tools. You’re not looking for a team or agencies to manage.
• You’ve built agents or automations that replaced manual work, and you can say what each one costs to run.
• You do well at startups or scale-ups, where priorities shift. You’d rather ship this week and improve next week.
• You’d rather run ten small experiments than one big bet, and you know when to stop one.
• You’re a strong writer who uses AI to produce more, not to write for you.
• You’re fluent with data: CRM data, APIs and basic SQL. Attio experience is a plus.
• You’ve launched several products or features at a fast-moving company, and turned what you learned into a process others could follow.
• You’ve managed or mentored at least one person, and you’d enjoy developing a coordinator into a stronger marketer.

Bonus points: experience with AI search and how buyers find vendors through it, marketing to enterprise brand, localization or compliance teams, partner or marketplace marketing, or helping launch a new category.

What we offer

• US$ [105,000–120,000] base + quarterly STI + equity
• A clear path to VP Marketing
• A direct line to the CCO and CTPO, and real room to build
