Senior Product Manager

ABOUT 390

390 builds operational software and systems for businesses and institutions.

Through 390 Work, we help businesses manage daily operations across sales, inventory, staff, customers, finance, tasks, approvals, records, production, and other key workflows within a single system.

We are building for businesses that need better visibility, coordination, standards, and control over how work gets done.

ABOUT THE ROLE

We are hiring a Senior Product Manager to take strong ownership of 390 Work’s product direction, execution, and improvement.

This is a founder-close role for someone who can understand complex business operations, turn customer problems into clear product decisions, work closely with engineering and design, and help 390 become easier to use, easier to adopt, and more valuable to customers.

This role is not for someone who only manages tasks or writes tickets.

We need someone who can think deeply, organize complexity, make product decisions, and move work forward with strong ownership.

The goal is to find someone who can gradually become the person responsible for carrying out 390 Work’s product execution on a day-to-day basis.

THE MISSION

Product Ownership

• Own the product roadmap and help prioritize what should be built, improved, delayed, or removed.
• Translate business goals, customer needs, founder direction, and product feedback into clear product priorities.
• Understand how different parts of 390 Work connect across modules and workflows.
• Help ensure the product remains coherent as it grows.

Customer and Market Understanding

• Speak with customers and prospects to understand real operational problems.
• Study how businesses currently manage sales, stock, staff, finance, customers, tasks, approvals, and records.
• Identify repeated pain points, product gaps, adoption issues, and workflow problems.
• Separate real product signals from one-off feature requests.

Requirements and Feature Scoping

• Write clear product requirements, feature briefs, user stories, acceptance criteria, and product notes.
• Break large product ideas into practical phases that can be designed, built, tested, and released.
• Clarify edge cases, user permissions, data flows, workflow states, and expected outcomes.
• Work with design and engineering to make sure requirements are understandable and implementable.

Product Design and Engineering Collaboration

• Work closely with Product Design to shape usable flows, screens, empty states, onboarding, and in-app guidance.
• Work closely with engineering to clarify scope, tradeoffs, feasibility, and release expectations.
• Make sure design and engineering solve the right product problem, not just complete tasks.
• Review builds before release to confirm that product behaviour matches the intended outcome.

Product Quality and Improvement

• Review existing modules and identify where 390 Work feels confusing, heavy, inconsistent, or incomplete.
• Improve product usability, activation, adoption, and customer value.
• Help define what success looks like for new features and product improvements.
• Track post-release feedback and ensure important issues feed back into product decisions.

Cross-Functional Alignment

• Work with Sales, Marketing, Product Education, Customer Support, and Engineering to keep product understanding aligned.
• Help Marketing and Sales understand what the product does, who it is for, and how to explain it correctly.
• Help Support and Product Education identify where customers need better guidance, documentation, or onboarding.
• Maintain internal product clarity so the team is not dependent on the founder for every product explanation.

WHO YOU SHOULD BE

• Have strong product management experience, preferably with B2B software, SaaS, ERP, CRM, operations software, fintech, business tools, or internal tools.
• Can understand complex workflows and simplify them into practical product decisions.
• Can work closely with engineers and designers without needing a large company structure.
• Is comfortable speaking with customers and translating their problems into product direction.
• Can write clearly and document product decisions properly.
• Has strong judgment and can prioritise without being told every next step.
• Can think from both the business owner’s perspective and the end user’s perspective.
• Can operate with ownership, initiative, and urgency.
• Is comfortable working in an early-stage company where clarity has to be created, not inherited.

SUCCESS METRICS

In this role, success means:

• Product decisions become clearer and better organized.
• Engineering receives better product requirements and fewer unclear instructions.
• Product Design has clearer problems to solve.
• Customer feedback is captured, structured, and turned into useful product action.
• New features are scoped better before development begins.
• Existing modules become easier to use and more coherent.
• 390 Work becomes easier for customers to adopt and depend on.
