Lead Software Engineer - Growth
What We Do
We are building the infrastructure that will power every AI application you'll use in the future. Our mission is to create the tools that enable AI models to take real actions in the real world.
Why This Is The Opportunity of a Lifetime
Founder-Market Fit: Our CEO previously founded Stormpath (acquired by Okta), where he created the first Authentication API for developers.
Dream Team: We've assembled a team of experts from Okta, Redis, Microsoft, Splunk, Ngrok, Google, Airbyte, Disney, and HPE who've built and founded multiple successful developer platforms.
Precise Timing: We're at the inflection point of AI adoption. The biggest problem isn't better models - it's connecting AI to real-world actions. That's us.
Massive Market: We're building critical infrastructure for the biggest technological shift of our generation. Every AI app will need what we're building.
Backed By The Best: Our investors have backed Databricks, Clickhouse, MongoDB, Perplexity, Cohere, ScaleAI, Confluent, Elastic, and Firebase. They see what we see - this is going to be huge.
What You'll Do
Own the technical direction and delivery for Growth engineering: activation flows, onboarding, billing, docs, and developer experience surfaces across the product.
Ship code daily across the stack - React frontend, Go and Python backend services - while making architecture decisions that hold up as the team scales.
Lead a small team (1–2 engineers today, growing): unblock them, review their code, and set the technical bar.
Build the experimentation and measurement layer: feature flags, A/B tests, funnel instrumentation, and cohort dashboards so the team can run data-driven activation experiments.
Reduce time-to-value by identifying and eliminating friction in the MCP Gateway setup, OAuth configuration, onboarding UX, and documentation.
Navigate cross-team dependencies with Platform and Tools engineering: bring funnel data, propose interface changes, and ship contributions to services you don't own when it unblocks activation work.
Build leverage by using automation and AI tooling to compress cycle times. Projects that take a week today should take a day next time.
Required Skills
7+ years of software engineering experience, with demonstrated technical leadership (tech lead, staff engineer, or similar - formal title matters less than the work).
Deep backend and systems expertise - you've built and maintained production APIs, designed database migrations, worked with PostgreSQL, and debugged distributed systems.
Go and/or Python experience strongly preferred.
Architectural fluency across the full stack - you understand how services, frontends, and data layers stitch together to create a product experience. You can translate between backend infrastructure and user-facing surfaces.
Frontend savvy - you may not be a frontend specialist, but you can read and contribute to a React codebase, give meaningful feedback on UI decisions, and collaborate effectively with frontend engineers.
Experience working across several services operating independently - you've navigated shared libraries, cross-service dependencies, and coordinated deployments without breaking things.
Growth or product engineering mindset - you think in funnels, activation metrics, and experiments, not just features. You've measured the impact of what you've shipped.
Experience leading small teams - code review, technical mentorship, architectural decision-making, and the judgment to know when to build vs. when to cut scope.
Comfort with ambiguity - pre-PMF, early team, narrow charter that will expand. You make good decisions with incomplete data.
An insatiable desire to ship.
Bonus Points
Experience with OAuth/OIDC flows, identity systems, or auth infrastructure.
Familiarity with the MCP (Model Context Protocol) ecosystem or similar agent-tool protocols.
Experience building developer onboarding, activation funnels, or PLG infrastructure.
You've set up growth data infrastructure: PostHog, feature flags, funnel dashboards, behavioral cohorts.
Open-source contributions.
Experience at an early-stage startup, and you loved it.
Notes
This is an in-person role located in our San Francisco (SOMA) office.
Join The Movement: We're not just building a product - we're leading a movement to transform AI from just chatbots to agents that can take actions against real systems. This is your chance to be at the forefront of that revolution.
If you want to look back in 5 years and say, "I helped build that", then we want to talk to you.
