Forma.ai is a Series B startup that's revolutionizing how sales compensation is designed, managed and optimized. We handle billions in annual managed commissions for market leaders like Edmentum, Stryker, and Autodesk.

Our growth has been fuelled by our passion for fundamentally changing and shaping how companies use sales intelligence to drive business strategy.

We’re welcoming equally driven individuals who are excited about creating something big

About the Team We build enterprise software that helps organizations optimize sales performance, enabling go-to-market agility. Our engineering organization includes multiple product application teams responsible for delivering core customer-facing capabilities. We are seeking a

Senior Staff Backend Engineer

to join our application teams and help set technical direction across multiple domains within engineering. You'll work alongside staff, senior, and early-career engineers, and partner closely with engineering leadership to define, evolve, and scale the systems that power enterprise-grade product workflows. This is an prospect to own complex, multi-domain technical problems and shape product direction beyond a single team. We are low on meetings, high on accountability. Most of the teams are in the EST time zone, but we have a few located in AST, PST, and Central as well.

What you'll be doing You will play a pivotal role in shaping the technical direction of our application stack across multiple domains. You will lead development efforts for our most complex initiatives, the kind that span two or more teams or product areas, and serve as a technical benchmark for system design, code quality, and long-term maintainability. You'll operate at the intersection of data modelling, business logic,



and enterprise-scale reliability, and your work will often set standards that neighboring teams adopt. This remains a hands-on role; you personally ship the hardest work in your domain rather than only setting direction for others.

As a Senior Staff Engineer, you are expected to operate with a very high degree of ownership, trust, and independent judgment. This includes proactively identifying architectural risks that cross team boundaries, surfacing edge cases or constraints others may not see, and advocating improvements that strengthen the long-term integrity of the systems you own. Where the opportunity is there, and especially when you're excelling in the role, your influence can extend across the broader org, but the core expectation is deep ownership of complex domains spanning multiple teams. We value engineers who bring forward thoughtful, sometimes contrarian perspectives, even when they challenge deeply held assumptions, and who help neighboring teams see around corners.

You will:

Design and evolve backend services and architectural patterns that power product workflows across two or more teams or domains.

Architect data models representing hierarchical & graph structures, relationships, and large-scale enterprise datasets, setting standards that other teams in adjacent domains build on.

Build deterministic,



reliable systems that allow customers to reason clearly about their data.

Drive architectural decisions that span multiple domains, balancing extensibility, performance, and operational simplicity.

Improve observability, testing strategy, and production reliability across the systems and domains you own.

Partner closely with Product and Engineering leadership to translate ambiguous, high-stakes business requirements into clean, scalable designs.

Mentor engineers across levels, including other staff-level engineers, and help raise the bar for backend engineering within your domains and beyond.

Use and champion the use of AI tooling to improve implementation velocity while thoughtfully investing in technical and product specifications.

What We're Looking for:

Extensive experience designing and building complex backend systems in production environments at scale.

Strong product judgment. You learn the customer's domain and workflow deeply enough to shape what gets built alongside Product, catch customer-experience problems during design rather than after ship, and push back on requirements when the proposed solution doesn't fit how customers actually work.

A track record of leading architectural direction across multiple teams or domains, not just within a single team.

Demonstrated ability to surface unarticulated risks, propose alternative approaches, and advocate for architectural improvements with sound technical reasoning, including the ability to influence decisions outside your immediate team.

Deep expertise in at least one production-grade backend language (e.g., Python, Java, Kotlin, Go, C#, etc.).

Strong foundation in relational schema design, d
