Broken Build is a remote-first product company looking for a Customer Success and Growth Specialist who works both sides of the relationship: turning the signals our customers already send us into expansion, and reaching out to new people who have never spoken to us yet, from managers and admins at organisations running Jira to the independent agile coaches and consultants who shape how teams work.
 

This is a customer-first role with a commercial, outbound edge. You will work the signals our customers already send us, proactively hunt for new relationships worth building, map who is who inside each account, and open conversations that are specific enough to earn a reply. If you love being close to customers, enjoy the detective work of finding the right person, and spot opportunity in the details, read on.
 

What you will do day-to-day
 

• Work the customer signals. Watch our support queue, demo-call requests, security and compliance enquiries, and billing and admin contacts. Read each one for what the customer actually needs, and for the opportunity behind it (a trial that could convert, an existing customer who could expand, a lapsed customer worth re-engaging).
• Hunt for new relationships. Proactively find and reach the people who should know us but do not yet: managers and admins at organisations using Jira, and the independent agile coaches and consultants who influence how teams work and what tools they adopt. Open with something specific to them, never a generic intro.
• Map the account. For each account in scope, learn who the admin, the team manager, the agile coach, and the executive are. Build and keep that picture current in our CRM using LinkedIn Sales Navigator, Apollo, and the public web, tied to what we already know about the customer.
• Open helpful conversations. Reach out with a personalised message that references the real moment (the ticket they filed, the request they made, the thread they posted in, the talk they gave), and route to a demo or a deeper conversation when it helps them.
• Listen and learn on calls. Pick up how each kind of stakeholder describes their problem in their own words (a manager asks "when will it be done", a coach talks about flow and predictability, an admin names a specific configuration), and bring those verbatim insights back to the Product team.
• Drive growth, expansion, and retention. Win new relationships, spot where existing customers could get more value, re-engage customers who drifted away, and hand qualified opportunities to an Account Executive, Solutions Engineer, or our CEO with a clear, well-documented brief.
• Keep the record honest. Every interaction is logged. Every contact has a role and context attached, so the next conversation always builds on the last.

Must-Have Requirements
 

• Advanced/fluent English (C1, C1+): you write a clear, warm message and run a customer call without friction.
• 2 to 7 years in B2B SaaS in customer success, account management, or technical/customer support, with a genuine commercial instinct and a willingness to reach out to people who do not know us yet.
• Research craft. You can understand an account and its people from LinkedIn, public org charts, community profiles, and a company's own content before you ever reach out.
• Strong writing. A clear, personable message and a one-screen account brief, with no corporate filler.
• CRM discipline. You treat the CRM as the source of truth, not an afterthought.

Skills That Make You Stand Out
 

• Atlassian-ecosystem fluency. Hands-on familiarity with Jira and Confluence, the Atlassian Marketplace, Cloud vs Data Center, or the Solution Partner world. If you do not have it yet, genuine curiosity to ramp fast counts for a lot.
• Agile vocabulary. Comfort with Scrum, Kanban, or scaled-agile language (SAFe, LeSS, Nexus) and the day-to-day pains of the people who work in it.
• Customer-success, support, and outbound tooling. Any of Zendesk, Intercom, Freshdesk, HubSpot on the customer side; LinkedIn Sales Navigator, Apollo, Reply.io, Snov.io, or Expandi on the outbound side.
• AI-assisted research. You already use an LLM for research, account scoring, and first drafts, and you know the message that reaches a customer has to sound like a person, not a model.
• A public footprint: an active Atlassian Community profile, a meetup talk, prior consulting in the ecosystem, or any writing under your own name.

Preferred Career Backgrounds
 

• Customer Success Manager (Atlassian or B2B SaaS) who has already run expansion conversations and is comfortable reaching out to new contacts: our ideal profile.
• Customer / Technical Support Manager with a commercial instinct, ready to turn support into growth and proactive outreach.
• Account Manager focused on retention and expansion who wants a more proactive, account-mapping and prospecting role.
• SDR / BDR in B2B SaaS who wants to work closer to customers and value, not just top-of-funnel volume.

Benefits
 

• Remote-first work in a self-funded product company with no bureaucracy and real ownership.
• Be part of a team whose apps are used by globally recognised enterprises across 60+ countries.
• Work directly with customers from around the world, and with our Product team and CEO.
• A performance bonus on closed deals: after your trial period, the deals you help close earn you a bonus, so strong results translate directly into your reward.

Interview Stages
 

1. Online Interview #1 (45 to 60 mins): a conversation with our CEO about how you work with customers and reach new ones, with a short live account exercise.
2. Small Home Task: pick a real (anonymised) customer signal we provide, research the account, and draft the first outreach message plus a one-screen account brief.
3. Online Interview #2 (30 to 45 mins): walk through your home task and discuss how you would ramp in our ecosystem.

About the role:

We're looking for a Product Manager to take full ownership of our core products — the tools our teams, clients, and partners rely on every day. You'll guide them from the first idea and roadmap all the way through launch and the improvements that follow.

You'll shape what we build and why, working closely with our Software Architect, designers, and engineers to turn business goals into real products that ship.

This is a hands-on role with a strategic edge. You'll help set the direction for the whole portfolio, but you'll also be in the details of the backlog every week. Think of yourself as the link between leadership, the people who build the product, and the people who use it.

What you'll do:

• Own the product strategy and roadmap across the full portfolio, balancing the long-term vision with what we deliver each quarter. You'll recommend what gets built, what gets cut, and what can wait.
• Turn that strategy into a clear, prioritized backlog. Write requirements and user stories that design and engineering can pick up and run with — without needing a follow-up meeting to figure out what you meant.
• Work with the Software Architect and engineering leads on trade-offs, scoping, and sequencing. You won't be writing code, but you'll be comfortable enough in these conversations to ask good questions and make sound calls.
• Partner with designers through discovery, prototyping, and testing, making sure the experience for users and the outcomes for the business line up.
• Keep everyone across the business aligned — leadership, sales, support, marketing. Communicate trade-offs honestly, and push back when it's the right thing to do.
• Talk directly with clients and partners when it sharpens our thinking — discovery calls, feedback sessions, and the like.
• Define what success looks like before work starts, then measure the results after launch so we actually learn what worked.
• Keep an eye on the market and competitors so the portfolio stays well-positioned and we spot opportunities early.

What we're looking for:

• 5+ years in product management, ideally with experience owning more than one product or a full portfolio.
• A track record of shipping, not just planning. We want someone who's taken ideas from a blank page to a live product more than once.
• Strong prioritization instincts. You can explain a "no" as clearly as a "yes."
• Comfortable working in agile teams and with tools like Asana, Notion, or Figma.
• Excellent communication, written and verbal. You can explain a trade-off to a non-technical exec and a business goal to an engineer, and both walk away clear.
• An analytical mindset. You reach for data before opinion, but you don't hide behind it.

• Genuinely at ease talking with customers and partners — you look for those conversations rather than avoiding them.

   

Working with AI:

We expect AI to be a real part of how you work — not a side experiment, but a daily habit. And if you're not fully there yet, you're eager to get there fast.

• You use tools like Claude or ChatGPT in your everyday product work: drafting PRDs and user stories, summarizing research, making sense of feedback, and pressure-testing your own thinking.
• You're comfortable setting up simple workflows where AI does a first pass — drafting or summarizing — and people review and refine.

• You know where AI tends to fall short, and you use it with good judgment.

   

Nice to have:

• Experience in logistics or a similar operations-heavy field.

• Conduct deep-dive analysis of active campaigns, optimizing for key performance indicators (ROI, CPA, LTV) to maximize profitability.
• Develop detailed briefs for the design team and motion designers; constantly test new creative angles and landing pages.
• Monitor daily expenditures and performance metrics, providing detailed daily reports to ensure budget efficiency and target alignment.
   

Requirements:

• At least 2+ years of hands-on experience in Media Buying, with a track record of managing high-volume traffic.
• Deep knowledge of the Gambling/iGaming vertical is mandatory.
• Strong experience in launching and scaling campaigns specifically for the Tier-3 market.
• Experience managing significant monthly budgets of $50,000+ with proven ROI.
• Solid experience working within professional arbitrage teams or media buying agencies.
• Expert knowledge of launching and optimizing campaigns for both iOS and Android platforms.
