We need a Backend Engineer to build infrastructure for cutting-edge multimodal AI systems at massive scale. You'll be responsible for the distributed systems that power millions of AI voice conversations daily, operating at the intersection of LLMs, voice AI, and real-time infrastructure. This role requires deep expertise in ML systems design and distributed architectures. You'll implement robust safety and alignment frameworks for AI systems, build scalable monitoring to detect unexpected model behaviors, and ensure our AI infrastructure complies with financial regulations. You'll balance rapid AI feature deployment with architectural scalability while handling the unique challenges of real-time voice AI at scale. The ideal candidate has experience with LLM infrastructure, voice AI technologies (ASR, TTS), and a track record of building production AI systems at scale. You'll thrive in our high-intensity environment where we're pushing the boundaries of conversational AI infrastructure.
As an early-stage company building at the frontier of AI, we work with high intensity and commitment. While schedules can vary by role and team, many weeks will demand extra focus, flexibility, and time—particularly during major launches and high-impact sprints. We're seeking those who are aligned to and able to commit to that expectation, which includes 5 days per week in our San Francisco office.
This isn't for everyone, and that's okay. We're looking for people who thrive in high-stakes environments, who find energy in solving hard problems alongside exceptional teammates, and who want their work to have immediate, measurable impact.
At Takeoff, every engineer owns relationships directly with customers. You won't be hidden away coding in isolation. You'll join customer calls, understand their challenges firsthand, and see the immediate impact of your work. Each engineer is responsible for customers generating millions in revenue. When you ship a feature, you'll hear directly from the sales teams whose lives you've transformed.
You'll also own a meaningful piece of the company. With 0.10% to 2.00% equity grants per teammate, early employees will see a substantial share of the returns as we scale. We believe in real ownership that reflects your impact on our growth.
We'd love to hear from you. Send us your resume and a note about why you're excited about Takeoff.
