Staff Software Engineer

About the role

Why Shuttlebase? Imagine websites that rebuild themselves on autopilot to sell more, convert better, and grow faster. At Shuttlebase, we’re making that happen — merging generative AI, large-scale data pipelines, and experimentation into a self-evolving web. We’re a well-funded, very early-stage startup with a massive vision. Joining now means you’re not just an employee — you’re helping set the technical and cultural DNA of the company. If you’ve ever wanted the autonomy of a founder with the backing of top-tier investors, this is it.

Responsibilities

• Work at the forefront of generative AI and agentic flows - build systems that let AI autonomously reason, experiment, and deploy real changes to the web.
• Architect the next generation of Shuttlebase's experiment engine - scalable, observable, fault-tolerant, built for millions of daily events.
• Design and evolve our backend infrastructure across Python (Flask-RestX), serverless AWS, and data pipelines (ClickHouse, Postgres, Kinesis, Firehose, S3).
• Drive technical strategy - define our engineering principles, evolve architecture across microservices, ingestion, and LLM-driven systems.
• Mentor and multiply - uplevel senior and mid-level engineers through code reviews, pairing, and design docs.
• Collaborate cross-functionally - work with AI, product, and data science to translate business needs into resilient systems.
• Prototype and push boundaries - bring ideas from concept to production fast, balancing experimentation and rigor.
• Raise the bar on performance, security, and reliability as we scale toward SOC 2 and enterprise clients.

Requirements

• 8+ years of experience designing and shipping production systems at scale (bonus: 0→1 or startup environment).
• Strong expertise in Python, AWS, and JavaScript - you’re comfortable owning both backend and frontend architecture.
• Proven ability to design distributed systems (event-driven, microservices, or data-heavy architectures).
• You’ve been a technical lead or staff engineer - mentoring peers, reviewing designs, and setting engineering standards.
• Bias toward action and clarity - you simplify, document, and deliver.
• Deep curiosity about AI and experimentation - you love systems that learn and adapt.
• Bonus: experience with ClickHouse, LLMs in production, or ecommerce/analytics infrastructure.
