GTM Engineer

Every breakthrough in trade infrastructure has followed the same pattern: reduce a transaction cost, expand the market. Containerization for goods. SWIFT for money. Stripe for payments. Compliance is one of the last and largest — and the hardest, because trade rules aren't data to be looked up. They're a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.

Sphere built the system that solves it. Our AI (TRAM) ingests global trade law, interprets it, resolves conflicts across jurisdictions, and produces compliance determinations more reliable than human experts. We handle the entire lifecycle — calculation, registration, filing, remittance — at millisecond latency with zero downtime.

• Backed by a16z and YC. $21M Series A, 30%+ month-over-month growth, customers include ElevenLabs, Replit, Deel, Runway, and Lovable.

• Small team, global surface area. Everyone owns a domain that would be a full team at a larger company. San Francisco, five days in office.

• The problem keeps compounding.Expanding into input tax, withholding, e-invoicing, tariffs — each multiplies the complexity. Tens of millions of transactions today, billions ahead.

We’re hiring a GTM Engineer to build the systems that power our growth function.

This role sits at the intersection of GTM, operations, and Engineering. You’ll own the internal infrastructure behind how we run CRM, outbound, paid acquisition, SEO / GEO, and future growth channels. You’ll help turn a set of tools and workflows into a cohesive, scalable system the team can rely on as we grow.

We’re looking for someone who likes building from first principles, is comfortable in technical systems, and wants to work closely with go-to-market teams on high-impact problems. The role is not purely engineering or marketing; it’s a hybrid builder role for someone who can connect systems, data, and execution. You’ll help shape how growth operates day to day and build the foundation that lets the team move faster as we scale.

Within days

• Get up to speed on the current growth stack and how the team is managing CRM, outbound tools, paid advertising, and SEO / GEO today.

• Identify where our workflows are fragmented, manual, or difficult to scale.

• Start mapping the internal GTM systems needed to support the growth function.

Within months

• Build, own and improve the internal systems behind our growth function.

• Turn separate tools and channels into one cohesive, scalable operating system for growth.

• Build out localization efforts across North America, EMEA, APAC and LATAM as we expand globally

• Work cross-functionally with growth, marketing, design and engineering teams where needed.

• Experience with CRM systems, outbound tools, paid ads, and SEO / GEO workflows.

• Experience automating workflows either through workflow automation tools like Zapier or via Claude and other AI tools.

• Strong technical fluency, including comfort with SQL, analytics, automation, and systems thinking.

• A builder mindset. Practical, adaptable, and excited to create structure in ambiguous environments.

• Relentlessly curious. You don't wait to be pointed at the answer - you go find it, and you know when to pull in someone who knows more than you.

• Strong communication skills. We work at an extremely fast pace, so clear, concise communication is essential.

• Experience building GTM systems in a revops, salesops, early growth role

• Broader marketing fluency alongside strong systems-building instincts.

You'll thrive here if:

• You're a Dog. You've been underestimated, gone through struggle, and never stopped running. You have a chip on your shoulder and enormous drive. You look at Stripe, Deel, and Flexport all punting on compliance and think: good, that means the opportunity is ours. Hunger beats pedigree.

• Early stage is in your bones. You've built things where there's no playbook and nobody handing you the answer. You define the problem instead of waiting for instructions.

• You own it end to end. Give you a goal and you figure out your own path. Small team, global surface area — everyone owns a domain that would be a full team at a larger company. No one tells you how.

• You believe speed and accuracy are both possible. We're building a complex product that requires robustness and 100% uptime, and we have to build at our customers' pace. Move fast. Don't break things. Both.

• Being in the room is a feature, not a cost. Five days in SF isn't a policy, it's how the work gets done. The speed and density of collaboration we need doesn't survive over video.

This won't be a fit if:

• You need structure handed to you or ambiguity feels draining rather than motivating

• You want to manage people more than own hard problems (we're a flat, experienced team — everyone builds)

• You're used to "good enough" shipping (small errors have outsized impact here)

• Being in the room five days a week feels like a cost instead of a benefit
