Jobs

START HERE

Most of what we need is ordinary platform work. One part is not.

We run a multi-tenant SaaS platform on Kubernetes with a MongoDB data tier, and we are designing it for its enterprise stage. The hardest problem in the engagement is reshaping stateful workloads in production without losing data, and designing tenant isolation so that one customer's load cannot degrade another's.

If reshaping a StatefulSet's storage in a live cluster is a problem you have actually solved rather than read about, keep reading. If it is not, the rest of this list will look familiar and you will probably be bored.

WHAT YOU WILL OWN

The data tier. Design and implement high availability for MongoDB: replication topology, migration paths that are reversible at every step, and backup and restore that is verified rather than assumed.

Tenant isolation. Design multi-tenant resource isolation so workloads stay predictable as customer count and data volume grow. Noisy-neighbor behavior is the failure mode we care about most.

Release integrity. Mature the deployment pipeline so releases are deterministic and auditable, and so what is running matches what was declared.

Observability that means something. Define the service-level indicators that reflect real customer experience, and build the measurement behind them. We are not looking for more dashboards.

Async and background processing. Architect the model for long-running, data-heavy operations.

Capacity. Right-size resources against measured usage, introduce autoscaling, and load test at realistic data volumes.

Cloud strategy. Give us your long-term view. We are on Azure and are not planning to migrate, but we want an architect's assessment to plan against.

WHAT WE NEED TO SEE

You have done stateful surgery in production. Reshaping storage, promoting a standalone database to a replicated one, or migrating a data tier with a rollback path at each step. This is the one thing we cannot backstop with review.

You have solved tenant isolation for real. Not "we used namespaces." You have hit a noisy-neighbor problem, diagnosed it, and have opinions about which mitigations actually held.

You debug by measurement. You instrument and observe rather than reason from intuition, and you have been wrong about a bottleneck before and can say so.

You can read Node.js well enough to reason about where memory and time go. You do not need to write it.

You will disagree with a proposed design and explain why. You will be the most experienced infrastructure person here, and deference would waste the engagement.

5+ years in platform engineering, SRE or cloud architecture, with real design ownership on at least one production system.

English sufficient for written technical discussion and calls.

THE STACK, FOR MATCHING

Kubernetes and Helm in production, MongoDB, Azure and AKS preferred (equivalent AWS or GCP depth is fine), Terraform, Prometheus, Grafana, Alertmanager, Loki, Node.js services.

Nice to have: GitOps (Argo CD or Flux), k6 or JMeter, exposure to blockchain infrastructure or carbon markets. The domain is genuinely optional, we will teach it.

HOW TO APPLY

Send your CV and answer one question. It matters more to us than the CV does.

Describe a time you changed the shape of a stateful workload in production. A storage migration, a topology change, a database promotion, anything where the data had to survive. What was your rollback at each step, and what did you check before you started?

Answers that describe the happy path tell us less than answers that describe what almost went wrong. We are not looking for a keyword list.

That’s what Gravity of Luck means to us.

We’re building one of the fastest-growing iGaming products in Tier-1 markets, and we’re looking for someone who knows how to turn conversations into partnerships, and partnerships into measurable revenue.

About Gravira Group

Gravira Group is a fast-growing international iGaming company focused on Canada and Tier-1 markets.

We’re now scaling our Affiliate direction and looking for someone who can help us build a strong pipeline of high-quality partners.

Why this role exists

Affiliate growth starts with the right partners.

Finding them is only the first step.

The real challenge is turning cold contacts into commercial conversations, negotiations into signed deals, and signed deals into active traffic and measurable performance.

Your mission is to build and convert a qualified partner pipeline, with a strong focus on Canada, Tier-1 markets and Facebook traffic.

This is a commercial acquisition role.

You’ll own the process from finding the right partner and starting the conversation to negotiating partnership conditions and bringing the partner to first traffic and first FTDs.

After the deal is negotiated, critical information is transferred to the Account/Operations Manager for documentation, tracking and reporting.

• Searching for new affiliate partners and webmasters.
• Building and maintaining a qualified partner pipeline.

That’s what Gravity of Luck means to us.

We’re building one of the fastest-growing iGaming products in Tier-1 markets, and we’re looking for someone who enjoys bringing structure, accuracy and transparency to complex operational processes.

About Gravira Group

Gravira Group is a fast-growing international iGaming company focused on Canada and Tier-1 markets.

We build and scale our own products by combining Product, Acquisition, CRM, Payments, Engineering, Analytics and Operations into one high-performance system.

We move fast.

We make decisions based on data.

We trust ownership over bureaucracy.

As our Affiliate direction grows, we’re separating commercial acquisition from operational ownership and building a stronger operational foundation for the department.

Why this role exists

Affiliate growth creates more than new partnerships.

It creates more partner data, deal terms, payments, statuses, reports, follow-ups and dependencies between teams.

When this information is incomplete or inconsistent, small operational issues quickly become business problems.

Your mission is to make sure the operational side of Affiliate works accurately and predictably.

You’ll own partner data, reporting, documentation, follow-up control and internal affiliate processes, working closely with the Head of Affiliate, Affiliate Sales Manager, Finance, Analytics, Risk, Product and Marketing.

This is not a cold sales or partner acquisition role.

Your focus is making sure that once a partner enters the business, everything around that partnership is properly documented, tracked and visible.

What You’ll Own

• Maintaining and updating partner data in NetHunt CRM.
• Managing partner and deal information in Affilka.
• Entering, verifying and updating affiliate data after partner negotiations.
• Keeping partner statuses accurate and up to date.
• Owning daily, weekly and monthly affiliate reporting.
• Tracking payments, commissions, deal terms and follow-ups.
• Reconciling information between NetHunt, Affilka, reports and internal documentation.
• Monitoring missing information, inconsistencies and overdue actions.
• Supporting partner onboarding from the operational side.
• Controlling deadlines and preventing missed follow-ups or payment-related issues.
• Maintaining clear and reliable operational documentation.
• Identifying gaps in existing workflows and suggesting improvements.

• Improving reporting, data structures, workflows and automation where possible.

   

What Success Looks Like

Six months after joining Gravira Group:

• Partner information is accurate, complete and up to date.
• NetHunt, Affilka, reports and internal documentation remain aligned.
• Affiliate reporting is delivered consistently and without avoidable errors.
• Partner statuses, payments, commissions and deal terms are clearly tracked.
• Missing information and overdue actions are identified before they become problems.
• Partner onboarding runs through a clear and predictable operational process.
• Affiliate, Finance, Analytics, Risk, Product and Marketing teams have reliable information when they need it.
• Less time is spent searching for data, correcting inconsistencies or chasing missing information.

• Affiliate operations become more structured, transparent and scalable.

   

We’re Looking For Someone Who

• Has experience in the iGaming industry with Tier-1 products.
• Has experience in Account Management, Affiliate Operations, Partner Operations, CRM Administration, Support Operations, Data Operations or a similar role.
• Has strong attention to detail and can work accurately with structured data.
• Has experience with CRM systems, affiliate platforms, spreadsheets, reporting tools or operational databases.
• Has a strong level of Excel / Google Sheets.
• Can keep large amounts of information organized, accurate and up to date.
• Has strong follow-up discipline and doesn’t let tasks disappear.
• Has an analytical and process-driven mindset.
• Communicates clearly with both internal teams and external partners.
• Can work with repetitive operational tasks without losing accuracy or focus.
• Takes ownership of problems instead of waiting for someone else to notice them.

• Has English at B2 level or higher.

   

Nice to Have

• Hands-on experience with NetHunt.
• Hands-on experience with Affilka.
• Experience working with affiliate reporting and commission calculations.
• Experience with data reconciliation across multiple systems.
• Experience improving operational workflows or introducing automation.
• Experience working closely with Finance, Analytics, Risk, Product or Marketing teams.
• Experience in a fast-growing startup or international iGaming environment.

Why Gravira Group

This is a role for someone who likes things to make sense.

You’ll have direct influence over the structure and quality of our Affiliate operations and will work closely with teams across the business.

Your work will make partner information easier to understand, processes easier to follow and operational issues easier to catch before they become bigger problems.

We value:

Accuracy over assumptions.

Ownership over bureaucracy.

Transparency over information silos.

Process improvement over doing things the same way forever.

And people who notice when something doesn’t work — and take responsibility for making it better.

Build Gravity of Luck

At Gravira Group, luck isn’t random.

It’s the result of curiosity.

Of ownership.

Of speed.

Of hundreds of small improvements that compound over time.

If you’re the person who notices the missing field, the inconsistent number, the overdue follow-up or the broken process — and doesn’t rest until it’s fixed — you’ll feel at home here.

Build Gravity of Luck with us.
