About the Role
Siena is the first intelligence layer for customer experience. We're creating an operating system of AI agents that learn, remember, and act across every customer touchpoint—from support conversations to shopping experiences to voice and social media interactions. Siena doesn't just automate support; it powers shopping agents, builds persistent customer memory, generates actionable business insights, and creates empathetic interactions that feel human. We're transforming how businesses understand and connect with their customers, turning every interaction into intelligence that makes the next one better. The team: We're a small, distributed team that punches way above our weight. Every person here has outsized impact because we've built leverage into everything we do. This philosophy makes us faster and, frankly, more fun to work with. If you're excited about building something that doesn't exist yet, keep reading. We're building agents that don't just respond to customers—they remember them, learn from every interaction, and connect experiences across channels. About the role: You'll anchor on billing and invoicing — owning the day-to-day so the team can focus on complex cases and strategic work. From there, you'll operate as a generalist across compliance, legal intake, vendor management, and cross-functional programs. The work is detail-heavy and high-stakes. A missed invoice, an overlooked contract clause, or an incomplete audit trail has real consequences — for customers, for the business, for the team. But it's also high-leverage: every loop you close frees the team for bigger bets. This is an early-career role. We're open to exceptional new grads and candidates with 1-3 years of experience — what matters is raw aptitude, ownership instinct, and the ability to learn fast.
Responsibilities
- Own day-to-day billing and invoicing operations — issuing invoices, monitoring usage, drafting customer billing comms, and supporting dispute resolution
- Assist with legal and compliance operations — contract intake, RFPs and security questionnaires, audit cycles, and policy hygiene across the team
- Manage vendor operations and equipment inventory — from new tool requests and renewals to spend reconciliation and team equipment
- Support cross-functional programs and strategic initiatives — audit prep, tooling migrations, and documentation that keeps the team running
- Partner closely with Operations leadership on ad-hoc projects that scale with the company
Requirements
- Detail-obsessed and systems-minded — you break messy problems into steps, owners, and deadlines, and actually close the loops
- AI-curious and resourceful — you've built AI into how you think and work, whether through your job, side projects, or how you organize your own life
- Comfortable with dense material — contracts, policies, spreadsheets, and dashboards don't intimidate you; you orient quickly and flag what you don't understand
- Strong communicator — concise, warm, and structured, with the judgment to know when to flag, fix, or ask
- Trustworthy and discreet — you handle sensitive information with care, own open threads without being asked, and have patience for ambiguity without tolerance for stagnation
Qualifications
- B2B SaaS experience, especially CX, fintech, or AI
- SOC 2, GDPR, or ISO 27001 audit-adjacent exposure
- Paralegal or legal-ops background
- FinOps, RevOps, or usage-based billing experience
- Working fluency in Linear, Notion, HubSpot, or similar ops tools
