Your name may not start with A(ndrej) or B(oris); but hey, we are not hiring for A/B testing.
As an AI-Forward Engineer, you will be at the frontier of how AI transforms every function in our startup. You will experiment with, evaluate, and implement AI-powered tools and workflows that accelerate teams across product, engineering, data, design, as well as sales, operations, customer success, and product marketing. The AI landscape evolves weekly - you will be our vanguard: rapidly prototyping with products, then shipping the integrations that give our teams an unfair advantage. A successful candidate combines solid software engineering fundamentals with deep curiosity about the AI ecosystem and a drive to put the best tools in the hands of every team.
Our engineering culture: We operate with shared trust and no egos. We enjoy being "in this together" and collaborating on the challenges of a rapidly scaling business. We live out our company values of curiosity, ownership, simplicity, and GSD.
You will:

• Work closely with every function (product, engineering, data, design, operations, sales, and product marketing) to discover pain points and translate them into AI-enabled solutions
• Experiment with and implement AI-assisted developer tooling, leveraging Claude Code for agentic coding workflows and AI-enhanced CI/CD pipelines that help engineering teams ship faster with higher confidence
• Leverage frontier models (Claude, Gemini, Kimi, GPT) as core engineering tools, evaluating new model releases for coding, reasoning, and agentic capabilities, and integrating the best-fit models into team workflows as they evolve
• Build and evolve our AI-augmented testing pipeline: from product spec use cases through test cases, test data, unit tests, and end-to-end Playwright automation, all generated via Claude Code, plus large-scale codebase improvement and refactoring through AST-based tooling (Java/Spoon, TypeScript/OXC, Flutter Dart Analyzer)
• Evaluate and deploy AI-powered design tools, such as Figma, Pencil, Stitch, Veo, Nano Banana
• Integrate AI-native intelligence platforms into go-to-market, operations, customer success, and support workflows
• Stay on the leading edge of the AI tool landscape: continuously scouting, testing, and benchmarking new tools as they emerge weekly
• Create internal tools and interfaces (chat-based assistants, dashboards, browser extensions, Slack integrations) that make AI capabilities accessible to non-technical stakeholders
• Establish best practices for agentic engineering, model evaluation, cost management, security, and responsible AI use across the organization
• Instrument and monitor AI-powered systems for reliability, accuracy, and cost-effectiveness

What you bring:

• 2+ years in engineering or DevOps roles, you know how software gets built, tested, and shipped
• Well versed in multiple programming languages including TypeScript, Java, and Python
• Hands-on experience with Terraform, GitHub flows/actions, and CI/CD pipelines, and an instinct for where AI can accelerate them
• Knowledge of AWS
• Already building with AI, whether it's frontier models like Claude, Kimi, or Gemini, agentic coding tools, or something you hacked together last weekend
• Comfortable working across teams that don't speak your language (product, data, design, sales, ops), and translating their pain into working tools
• A tinkerer's obsession; Show us what you've built
• Bias for shipping over perfecting: you'd rather demo a rough v1 in an hour than a polished v3 next week

What's in it for you:

• Compassionate and driven colleagues in a fun environment where success is celebrated
• Accelerated career growth in a fast-growing company
• Coaching from experienced engineering leaders
• Direct access to executives and a transparent company culture
• Rare opportunity to change an industry and lives of millions
• We are reinventing healthcare / pharmacy - your (grand)parents and your (grand)children will understand and appreciate what you do
• Medical / Dental / Vision / 401K package that fits your needs
• Flexible Vacation Time Policy
• 12 Paid Holidays
• Work out of our Nimble HQ in beautiful downtown Redwood City

$152,000 - $285,000 a year
Open to Engineer, Senior, or Lead. What matters is what you could build, not your current title.
Please note

1. Applications need to include links to your Github repos -> show us what you've built.
2. This hybrid role is based in Redwood City, California. 2 - 3 days in office is required.
