Growth Ops

Location: San Francisco or Tokyo (hybrid)
Type: Part-time (20 hrs/week) or Full-time
Reports to: Head of Growth
Company: Jinba (YC W26)

About Jinba

Jinba is a YC W26 company building the automation layer for modern teams.

We help enterprise teams build and run AI-powered workflows that automate real operational work, compliance checks, internal tools, data pipelines, and system integrations, without maintaining bespoke software.

Today, Jinba-powered workflows are used in production by over 40,000 enterprise employees, across compliance, operations, and engineering teams.

About the Role

We’re hiring a Growth Operations person to execute and iterate on growth campaigns using Jinba’s existing tooling and strategy.

You’ll work directly with the Head of Growth, who owns the growth engine, strategy, and prioritization. Your role is to turn that strategy into running experiments—across channels—using tools that are already in place.

This role is ideal for someone who enjoys hands-on execution, structured experimentation, and tight feedback loops, rather than defining top-level growth direction.

What You’ll Do

• Execute growth campaigns across multiple channels (email, lifecycle, landing pages, outbound support)

• Use existing tools (LaunchDarkly, Mixpanel, email marketing tools) to run experiments and analyze results

• Translate hypotheses into concrete experiments with clear success metrics

• Monitor experiment performance and share structured learnings

• Iterate on messaging, targeting, and sequencing based on data

• Maintain clean experiment tracking and documentation

• Partner with engineering and design to ship experiment variations

• Ensure results are measured correctly and decisions are data-informed

What We’re Looking For

• Experience executing growth or lifecycle campaigns at a high-quality product company

• Strong comfort working inside analytics tools and dashboards (especially Mixpanel or similar)

• Experience running experiments using feature flags, A/B tests, or lifecycle tooling

• Ability to independently run experiments end-to-end once direction is set

• Strong attention to detail and follow-through

• Clear written communication and structured thinking

Nice to Have

• Experience working with product-led growth teams

• Familiarity with B2B SaaS or developer-facing products

• Experience supporting experimentation at high velocity

• Comfort working with partially defined problems and fast iteration cycles

Why This Role Matters

Growth at Jinba is highly hands-on and experiment-driven. This role works alongside the Head of Growth to increase the velocity of campaigns, experiments, and iteration cycles.

By taking ownership of campaign execution, measurement, and iteration, you help ensure that growth ideas move quickly from hypothesis to data—without getting stuck in tooling, setup, or analysis overhead.

You’ll have direct impact on how Jinba grows, with clear ownership over experiments and real exposure to decision-making in a YC company operating at high tempo.
