About Actively

Actively is building superintelligence for GTM teams. We train custom reasoning agents to think like a company’s best sales reps, and then use them to evaluate millions of datapoint about every single prospect account in the company’s TAM to feed their sales reps the optimal actions to take every day to maximize revenue.

Our customers include some of the fastest-growing companies out there — Ramp, Verkada, Justworks, Ironclad, etc. — for whom we’ve driven hundreds of millions of dollars in added revenue in the past year.

We’ve raised over $22.5M in funding, including a recent Series A led by Bain Capital Ventures

About the Role:

We’re looking for a Senior Engineer to help us build the systems that make Actively configurable, controllable, and powerful at scale — including UI-facing tools like User Management, and backend systems that support real-time routing, LLM outputs, and data operations.

This is a high-leverage, fullstack role for someone who loves digging into messy user problems, building production-grade tooling, and owning end-to-end product surfaces — from backend logic to UI clarity.

You’ll work closely with founders, forward deployed engineers, and GTM teams to ship features that help our customers adopt Actively faster and drive real revenue.

What You'll Do

• Own product experiences and backend logic for critical internal and customer-facing systems — including routing config, user/account setup, and deployment tooling.
• Build UI + API layers that expose LLM model outputs and allow operators to make edits, reroute flows, or tune how reps interact with Actively.
• Collaborate directly with internal stakeholders and customers to understand edge cases and deliver solutions that scale.
• Design and build systems that make onboarding, configuration, and debugging easier and more self-serve — for both our team and our customers.
• Improve core infrastructure and LLM pipelines where needed to support product surfaces you own.

What a Typical Week Might Look Like

• Shipping a UI/logic update to the User Management view to help CS teams visualize and adjust rep routing logic from the latest production run.
• Pairing with an FDE on a customer onboarding issue, then building internal tooling to streamline that experience.
• Collaborating with GTM teams on a new routing use case and building the backend logic to support it.
• Iterating on a config dashboard that lets operators turn on/off features for specific users or teams.
• Proposing a new internal API that reduces coupling across our LLM orchestration codebase.

Who You Are

• Product Engineer – 5–7+ years of experience building user-facing features and backend systems that power them.
• Deeply Product-Minded – You care about user workflows, UX clarity, and building tools that make complex things simple.
• Backend-Comfortable – You can own APIs, data models, and system design — and know when to optimize.
• Frontend-Capable – You can build and iterate on clean UIs using modern frameworks (e.g. React/TypeScript).
• LLM Curious – You’re interested in how AI and human-in-the-loop workflows can work together — and want to build those interfaces.
• Customer Obsessed – You love working close to users, especially internal teams who are power users of your tools.
• Execution-Oriented – You bias toward action, ship fast, and improve quickly based on feedback.

Bonus Points

• Experience building internal admin/config tools, workflow engines, or routing systems.
• Familiarity with sales tech (e.g. Salesforce, Outreach, Gong) or GTM data workflows.
• Prior experience in an early-stage startup or as a founder.
• Strong intuition for operational UX — tools that revops, FDEs, and CS teams love.
