We believe in creating an environment where teammates enjoy working together, celebrate successes, and have fun solving interesting problems.

Requirements

8 + years of experience building high-quality production software (Python preferred).
Demonstrated experience architecting and delivering asynchronous, high-throughput, distributed systems in production.
Strong expertise with FastAPI, Django, asyncio (or similar frameworks) in Python.
Proficiency with NodeJS, React, Typescript and/or Express (or equivalent) — with the ability to evaluate when to use which stack and to mentor others.
Deep knowledge of SQL and real-time or near-real-time distributed data processing systems (e.g., RabbitMQ, SNS, SQS, Kafka).
Strong cloud experience (AWS, Google Cloud, or Azure) and familiarity with DevOps practices, infrastructure as code, monitoring/observability, CI/CD pipelines.
Proven ability to navigate ambiguity, make principled trade-offs between speed and quality, and drive innovation while maintaining long-term sustainability.
Experience working in a fully remote, asynchronous, distributed team environment; excellent communication skills and ability to influence without authority.
Passion for emerging technologies and the curiosity to explore how they apply to real business problems.

Nice To Haves

Experience working with foundational LLMs (large language models) and understanding of the various approaches to maximizing their efficiency and reliability.
Experience in regulated industries (insurance, finance, healthcare) or high-compliance environments.
Previous experience in high-growth, fast-paced startup environments where you have helped scale the engineering organization.
Proven track record of mentoring senior and mid-level engineers, building high-performing teams, or leading technical communities.
Experience in public-facing technical work (open source, conference presentations, publications) is a plus.

Responsibilities

Define and drive the technical vision for one or more core platforms or domains, including architecture, infrastructure, tooling, and performance.
Design, develop, and maintain software applications that leverage foundational LLMs and are built with high performance, scalability, resilience, and observability in mind.
Lead cross-functional initiatives: collaborate with data scientists, product managers, other engineering teams, and infrastructure/DevOps to translate business strategy into scalable, technical roadmaps.
Serve as a technical mentor and coach: influence coding practices, meet quality standards, perform deep code reviews, share knowledge, and raise the bar for engineering excellence.
Actively drive architectural design and trade-off decisions, balancing fast iteration and long-term maintainability. You will gain buy-in from senior stakeholders across the organization and ensure alignment on strategic initiatives.
Own operational excellence: troubleshooting, debugging, and resolving issues across the entire stack; lead the on-call rotation; define and measure reliability metrics (SLA/SLO/SLI) and lead post-mortem follow-ups.
Evangelize best practices: proactively identify technical debt, propose improvement initiatives, and help deliver them; introduce new technologies and processes that accelerate team productivity and quality.
Represent the engineering organization externally when needed (conference talks, open-source contributions, partner engagements) to raise our profile and bring back learnings.
