Senior Software Engineer

As a Senior Software Engineer, you're not just writing code — you're setting the technical direction for the systems you own. You'll work directly with our VP of Engineering, CTO and Co-Founder Bruce Kim, and CEO Srinivas Njay in a collaborative, in-person environment where the best ideas win and shipping is the scoreboard.

This role is for the engineer who has seen what "going fast" actually costs, knows how to build systems that hold up, and still gets things out the door.

Lead the design and implementation of platform services — scalable, observable, and maintainable systems that power our AI products

Own technical decisions end-to-end: architecture, APIs, data models, performance, and security

Build and extend backend systems in TypeScript and Python; shape frontend experiences in JavaScript

Drive the integration of LLM-based and agentic AI capabilities into production systems — this is applied AI engineering, not research

Define and enforce engineering standards: code review, testing strategies, deployment practices, and incident response

Embed AI-native tooling (Claude Code, Cursor) into your daily workflow and help the team get better at it

Work side-by-side with product, design, and data — in the office, in real time, every day

5+ years of software engineering experience with a track record of shipping impactful, production-grade systems

A portfolio of work you led, not just contributed to — you can walk through design decisions, trade-offs, and outcomes

Deep proficiency in TypeScript and/or Python; solid JavaScript for frontend contributions

Strong platform engineering instincts: distributed systems, API design, cloud architecture (AWS/GCP), observability

Fluent in AI/ML engineering: you've built on top of LLMs, understand prompt engineering, and know where AI adds value — and where it doesn't

Experience designing systems under real constraints — latency, reliability, cost, and scale

BS/BA in Computer Science; graduate degree a plus (we take fundamentals seriously)

Self-directed and decisive: you identify problems before they're assigned, propose solutions before they're requested, and close loops without reminders

In SF, committed to 5 days/week — the collaboration is real and intentional

Production experience with conversational AI, dialogue systems, NLP pipelines, or agentic architectures

Background in fintech, banking infrastructure, or regulated financial environments

Experience being an early engineer at a startup that shipped successfully
