This position is open only to candidates currently based in Canada, who have valid authorization to work in Canada. Candidates based in Toronto are highly preferred.

About the Role

We are hiring a Senior Product Manager to own the front half of the delivery process: to make sure work starts with a business goal and a validated problem, not with a design, and that by the time something reaches engineering it is shaped, sequenced, and feasible.

Project

FinTech product built for the restaurant and hospitality space. We integrate with POS and scheduling systems and sit on top of the money flows those systems generate.

We grew fast in startup mode, and it worked as we have a live product, real customers, and real revenue. What we don't yet have is a delivery process that matches the size of what we're building. 

Required Hard Skills

• 5+ years in product management, including at least one product with real technical complexity behind it.
• Prior FinTech experience (payments, payouts, reconciliation, lending, banking, or embedded finance), or direct restaurant/hospitality tech experience (POS, scheduling, workforce management, delivery platforms).
• Demonstrable experience introducing or substantially reshaping a delivery process in a company that had outgrown ad-hoc ways of working. We will ask you to walk us through exactly what you changed, what resistance you hit, and what it measurably improved.
• Strong requirements practice: you can write and review PRDs, user stories, acceptance criteria, and flow documentation, and you know when to hand that off versus do it yourself.
• Experience working with third-party APIs or platform integrations, including the messy parts: partner limitations, versioning, data reconciliation, error handling, validation layer.
• Strong BA skills to act as an owner of the product requirements, including describing and maintaining the product backlog
• Strong product toolkit. We value strong processes over proficiency with any specific tool, but expect broad hands-on experience across modern product and AI tools, with the ability to select and adapt the right toolkit for the job. 

• Fluent English, written and spoken.

   

Required Soft Skills

• Comfort working alongside engineers on architecture and technical debt conversations with enough depth to understand the trade-offs, ask sharp questions, and be trusted in the room.

• Ability to hold a position with a founder-CEO. You'll be asked to change how initiatives currently start, which means disagreeing productively and often.

   

Nice to Have

• Hands-on familiarity with specific POS or scheduling platforms (Toast, Square, Lightspeed, 7shifts, Deputy, or similar).
• Experience with a product that had to earn back reliability and trust after a fast-growth phase.
• Track record building product analytics from a low baseline with instrumentation, funnels, defining the metrics that matter.
• Comfort with BPMN or similar process modeling.
• Multi-tenant SaaS or B2B2C experience.

Key Responsibilities

1. Shape the delivery process end-to-end: 

- Introduce and implement a discovery-to-delivery flow

- Establish where design, engineering, and BA input enter the process, and make technical feasibility a first-class input.

- Define the artifacts and quality bar for each stage of the delivery process.

2. Get the backlog shaped: 

- Break large ambiguous initiatives into slices that can be estimated, built, and released independently.

- Own the roadmap and its sequencing, and keep it honest about capacity and dependencies.

3. Balance new value against the debt

- Build a shared, evidence-based view of where technical debt is costing us delivery speed, reliability, or the ability to ship what's next.

4. Own the integration and domain surface

- Own the product side of our POS and scheduling integrations

- Translate FinTech constraints such as payments, reconciliation, settlement, data handling, compliance into requirements engineering can build against.

- Bring the operational reality of restaurants into product decisions: shift patterns, staff turnover, tips and payouts, peak-hour behavior, tax background, low tolerance for anything that slows down service.

Who this position is not for
This is a build-the-process role, not a run-the-process role. If you need an established framework to operate inside, this will frustrate you. If you've stabilized delivery in a company that outgrew its early habits, you'll recognize the work immediately.

Things you should know before applying:

• The process is genuinely not there yet. You are building it, largely alone, while shipping.
• There is real technical debt. Some of what you want to do will be slower than it should be, and part of your job is making that visible and getting it funded.
• Initiatives currently start closer to solution than problem, and changing that means changing habits at the top of the company. We know this and we're hiring for it - but it will take persistence.

Recruitment Process

• Introductory Call (45 min).
• HR Interview (1 hr).
• Technical Interview (1 hr).

• Founder/Client meeting.

   

We are looking for people who are motivated to learn, take ownership, and grow together with us.

Our client: US product company, an athletics management platform used by thousands of schools across the United States: rosters, eligibility, scheduling, officials assignment and payments. A mature product with real scale, now adding AI features to the core workflows.

You will own features end to end, across the stack, in a small team where what you ship reaches production the same week.

Format and time zone

Fully remote from Ukraine. The team is distributed across US time zones, with its core on US Central Time. We ask for a few core overlap hours daily, in practice from around 16:00-17:00 Kyiv time. Everything else is asynchronous and written by default, with a low meeting load.

What you'll do

• Build user-facing features in Node.js/Express and React with TypeScript, from spec to production
• Own the full slice: API design, database schema changes, rollout and the monitoring that follows
• Work AI-first every day: funded frontier models from Anthropic and OpenAI, agentic coding tools, and repo-level convention files so generated code follows the team's patterns. The tools are used hard, the output is reviewed by humans, and PRs say what was generated
• Bring your own practice to the team: custom skills, project conventions, prompts and workflows that make the whole team faster, not just you
• Raise engineering standards through code review, architectural patterns and targeted refactors
• Support what you ship on a light shared on-call rotation

Requirements:

• 5+ years shipping production software as a full-stack engineer
• Strong Node.js with Express (or NestJS) and React, both in TypeScript
• PostgreSQL: schema design, migrations, query optimisation
• Working knowledge of AWS (ECS/Lambda, Secrets Manager, CloudWatch) and CI/CD in GitHub Actions
• Daily, hands-on use of AI coding tools (Claude Code, Cursor, Copilot or similar). Not occasional autocomplete, but agentic workflows, custom skills that encode project conventions, and the judgement to tell genuinely good generated code from code that merely looks plausible
• Comfortable owning a feature alone, from database to UI
• English B2+ for daily written async communication

Nice to have

• Angular, for the parts of the platform built on it
• MCP servers, custom agent skills or other tooling you built around AI-assisted development
• React Native
• Domain experience in scheduling or logistics

ABOUT VOLLNA

Vollna.com helps freelancers and agencies win clients on Upwork: job filtering, AI proposals, and auto-bidding. 10 years on the market, 3,000+ users. Small team, you'll work directly with the founder.

THE ROLE

You'll own a portfolio of our paying clients: Automation agencies, Agency-plan teams, and established freelancers. Two goals: clients get results and stay, and the right clients move up to Automation. Your bonus is calculated from your portfolio's retention and MRR, so both count.

Upwork is tough right now. Clients who succeed are the ones whose profile, targeting, and proposals are set up right in the first two weeks. Your job is to make that happen.

WHAT YOU'LL DO

- Onboard new Automation clients: review their Upwork profile, tune job filters and AI qualifier settings, and set realistic expectations using our benchmarks.

- Run funnel reviews in the first month. Catch bad targeting, boost turned off, or a weak proposal template early.

- Spot Agency-plan clients who are ready for Automation and walk them through the upgrade.

- Build relationships with high-tier freelancers and agencies in the portfolio: quarterly check-ins, case studies, referrals.

- When a client is at risk, diagnose the problem and fix what's fixable.

- Document recurring problems so they become rules in our automated reports and Profile Audit, and the same fix doesn't need you twice.

- Pass client feedback to the founder and influence what we build next.

COMPENSATION

$700/month base, plus a monthly bonus as a % of your portfolio's MRR, tiered by portfolio churn.

Upgrades you drive raise your portfolio MRR, so expansion pays you the same way retention does. The portfolio is growing and your bonus grows with it. We'll review the tiers together after the first quarter.

On top of that: a one-time bonus for every new client you close from a demo.

Realistic total compensation at solid performance: $1,300-1,600/month and more.

YOU'RE A FIT IF

- You've personally done Upwork lead generation, as a bidding manager, lead-gen specialist, or agency operator, and you have before/after cases with numbers (profile improvements, reply-rate lifts, JSS recoveries).

- You know how connects, boosts, outbid rate, JSS, and proposal view rate work.

- You've used Upwork lead-gen tools. Knowing what annoyed you about them is useful here.

- 2+ years in a client-facing role: customer success, account management, or running lead-gen for clients.

- Fluent English, written and spoken. Our clients are in the US, EU, Pakistan, and India.

THIS IS NOT FOR YOU IF

- You want a fixed salary that doesn't depend on whether clients stay.

- You've done SaaS customer success but never actually worked on Upwork.

- You need tasks handed to you. There's a lot of autonomy here.
