Staff Engineer Location: Hybrid in Boston, MA Type: Full-time | Engineering Seniority Level: Staff (Individual Contributor, with Tech Lead potential)

Join Modulate as we pioneer the future of prosocial voice intelligence. At Modulate, we’re building voice technology that makes online spaces safer and more inclusive. Our real-time voice moderation platform, ToxMod, and our voice identity tools enable game studios, community platforms, and enterprises to better detect harm, prevent fraud, and enhance user trust—all while scaling securely and responsibly.

We’re looking for a Staff Engineer to help us architect, scale, and evolve our core product platform as we grow into new markets and customer segments. If you're energized by solving complex, high-impact problems that lack a clear roadmap, and you love helping others level up while doing so, this could be the right role for you.

Your Impact As a Staff Engineer at Modulate, you'll be a technical leader and systems thinker, working across the stack—but with a particular emphasis on frontend architecture, data persistence, and the interfaces that connect everything together. You'll operate as a key partner to the Director of Engineering, diving deep into critical technical challenges that matter most to our mission.

Your work will directly impact:

The scalability and resilience of our real-time moderation tools

The intuitiveness and reliability of the experiences we deliver to users

The growth of our engineering team’s technical maturity and long-term impact

Our ability to safely scale into sensitive and high-compliance industries

This role is perfect for someone who resonates with the Solver archetype (à la Will Larson): a trusted agent of the organization who thrives in complexity and brings order to ambiguity.

As the team evolves, there’s also room to transition into a Tech Lead role focused on a strategic domain.

What You’ll Do

Provide technical direction across the engineering org: guiding architectural choices, mentoring teammates, and ensuring we’re building scalable, maintainable systems.

Dive deep into thorny problems in partnership with Director of Engineering. Guide development of complex projects across our products with an emphasis on frontend interfaces and high-performance data storage and retrieval patterns.

Design and evolve our web application architecture to support real-time workflows and robust moderation and investigation tools.

Collaborate with product managers, backend/ML engineers, and design partners to ensure user-facing tools are intuitive, reliable, and performant.

Shape long-term technical strategy around data models, storage, observability, and operational reliability.

Contribute to roadmap planning, technical scoping, and standards definition across teams.

What We’re Looking For

Clear, thoughtful communicator and collaborator. Comfortable operating across product, design, and platform teams.

Effective in making tradeoffs between speed and quality in order to balance short- and long-term org needs.

Org-first engineer with demonstrated record of raising the team along with themselves.

Deep proficiency in modern frontend development and frontend system architecture.

Strong practical experience with database design, performance tuning, and data modeling, including relational and non-relational databases.

Demonstrated ability to navigate and set direction in ambiguous or rapidly evolving environments.

8+ years of software engineering experience across multiple layers of the web stack, with a strong record of technical ownership and impact.

Bonus: familiarity with cloud infrastructure (AWS preferred), infrastructure-as-code, and DevOps practices.

Competitive salary + equity

Full health, dental, and vision coverage

Flexible PTO, with a strong culture of taking it

Weekly team lunches with dietary accommodations
