Software Engineer (Backend & AI Infrastructure)

Location: San Francisco, CA

Hybrid | Full-time

Compensation: $160K – $300K + Equity

Our client is a venture-backed technology firm based in San Francisco that is redefining the global research industry through AI-powered user interviews. By leveraging advanced AI-moderated technology, the platform enables global enterprises to achieve deep qualitative insights at unprecedented speed and scale. Currently serving world-class brands across the technology and consumer sectors, our client is disrupting a $140B market by replacing slow, high-cost legacy services with high-performance automated solutions.

Following a breakout year characterized by 8x growth, the organization recently secured a $30M Series B funding round led by top-tier Silicon Valley investors. The engineering team is currently scaling to support the rapid adoption of AI-moderated research as the new industry standard. This is a high-impact opportunity for a Backend Software Engineer to join a lean, elite team of 30 in San Francisco and take ownership of mission-critical infrastructure.

Key Responsibilities

Staff Software Engineer (Backend)

Location: San Francisco, New York, or Remote (US)

On-site/Remote| Full-time

Compensation: $225K – $300K 

Our client is a high-growth, venture-backed organization (YC W24) that has raised over $35M to pioneer the next generation of autonomous digital workers. Unlike traditional chatbots or copilots, our client builds fully autonomous "AI employees" that research leads, manage complex outbound sequences, handle deliverability infrastructure, and self-optimize through behavioral patterns.

Currently at $8M+ ARR and scaling rapidly, the organization is deep in the development of its next-generation platform—a step change in the capabilities of AI agents. The backend is the core of this transformation, processing millions of signals to facilitate autonomous decision-making. Our client is seeking a Staff Software Engineer to serve in a foundational role, owning major segments of the platform infrastructure and driving high-throughput AI orchestration. The engineering culture is flat, high-velocity, and results-oriented. There is no red tape; engineers are expected to own outcomes end-to-end, from architecture and design to deployment and monitoring.

Key Responsibilities

Software Engineer (Java Generalist)

Location: US - Open to Europe if happy to overlap with EST

Compensation: $160K - $200K

Our firm has been retained by a high-growth, mission-driven technology company to find a world-class Principal Java Systems Engineer. This is not a role for "glue" engineers who connect off-the-shelf components; this is for the engineer who sees performance ceilings as a personal challenge and prefers squeezing 30% more throughput out of clean Java over renting 30% more cloud compute.

Our client is building a high-performance, publicly visible immutable ledger. In an industry where people "move fast and break things," this team operates like NASA: moving fast while ensuring correctness, performance, and efficiency are 100% right the first time. You will join an elite team where you aren't a cog in the machine—you are the architect building it.
