Join a Company That Invests in You

Seeking Alpha is the world's leading community of engaged investors. We’re the go-to destination for investors looking for actionable stock market opinions, real-time market analysis, and unique financial insights. At the same time, we’re also dedicated to creating a workplace where our team thrives. We’re passionate about fostering a flexible, balanced environment with remote work options and an array of perks that make a real difference.

What We're Looking For

Do you look at websites and think about how they might be personalized? Do you use websites and apps and think about how their features have been designed to be best for a lot of different users? Do you read articles with statistics and think about how they may be misinterpreting the data to get their results? If these things describe you, and if you’re great at SQL and have experience analyzing website data, you’re someone we want to talk to.

We’re looking for a Senior Data Analyst with experience analyzing website data. Our data analyst team analyzes everything on our website, not only for their immediate use but also for how they connect to high-level company KPIs. Our Analysts analyze raw data, not only pre-aggregated data, to extract just the right information and diagnose what is happening on our site.

The role requires understanding web development and how data is gathered, analysis of site usage and a/b tests, data visualization, and how different kinds of data can be presented most clearly, and business KPIs and how they are measured.

But more than that, we’re looking for experienced analysts who can bring us new ideas about how to analyze and extract insights from website data. Our ideal candidates have measured KPIs that we haven’t measured or used new ways to explain user retention, or analyzed features of users' data that we haven’t analyzed.

The best thing about our work is that we’re part of an incredibly data-driven company. Everyone from the CEO down uses data every day. The data teams are involved in every single thing the company does.

What You'll Do

• Analyzing the behavior of users on our site and apps:

-Build and maintain dashboards that visualize the usage of single or multiple features and how that usage drives company KPIs.

-Answer questions about site usage or user behavior based on deeper analyses.

• Analyze and track high-level KPIs such as conversion, retention, churn, recurring revenue, engagement, cross-device usage, e-mail and notification usage, and more.
• Communicate with business stakeholders on analysis results, how they relate to business, and what business suggestions result from the analysis.
• Run the whole data flow for site and app features, from defining KPIs, specifying data collection for development team implementation, and building and maintaining iterative versions of dashboards with both low-level and high-level views of collected data.
• Split tests of product features:

-Design a test with clear success criteria

-Monitor test integrity

-Analyze results and give recommendations

-Use segmentation and clear cohort analysis to validate significant conclusions

-Conduct exploratory analysis to identify trends and opportunities

Requirements

• A minimum of 5 years in a B2C website-related Data Analyst position
• Strong SQL skills with experience writing complex and efficient analytical queries
• Demonstrated experience with working in English directly with business stakeholders, understanding their needs, and explaining results
• Understanding of website development and operations and how they connect to data gathered.
• Experience with data visualization tools (Looker/Tableau/PowerBI, etc.)
• Experience with report writing and technical requirements analysis, business process modeling/mapping, methodology development, and data modeling

About the Role
 

We're building a card-acquiring platform from scratch — and there's a critical layer that sits between engineering and finance that nobody owns yet: how the product actually moves money.

That means merchant and BIN onboarding, scheme processing, settlement and reconciliation, fiat payouts via SEPA and SWIFT, and making sure all of it is safeguarding-compliant. Right now this layer lives across our CTO and CFO. You'll own it — end to end.

No legacy systems. No bureaucracy. No ticket conveyor belt. Just you, a small senior team, and a genuinely hard domain where the decisions you make in the first six months will shape how money flows through the platform for years.

This is not a CFO role — we don't expect P&L, capital adequacy, or FP&A. It's not a Scrum PO or a BA. It's the owner of the financial and payments product layer: someone who digs into the domain themselves, writes specs engineers can build from, and makes product decisions. Disputes/chargebacks, FX, and the merchant-facing portal sit in adjacent roles.

What You'll Own:
 

• Merchant & BIN onboarding — design how merchants get set up in our core processing platform, end to end.
• Scheme processing — get into the mechanics of authorisation, 3DS, clearing and settlement, and own the product decisions that follow.
• Settlement & reconciliation — define how money moves from scheme settlement into our ledger and through to safeguarding accounts. Spec it to the point engineering can build.
• Fiat payouts — own the product side of SEPA and SWIFT payouts through our banking partners, including what we need from each integration.
• Safeguarding — make sure every money movement decision is designed with regulatory requirements in mind, in close collaboration with the CFO.

You'll Be a Strong Fit If:
 

• You have 4–6+ years in product at a payments or fintech company — ideally regulated. You know what that means in practice.
• Card acquiring isn't new to you: BIN sponsorship, interchange, scheme fees, 3DS, PSD2 exemptions — you've worked with these, not just read about them.
• You can take a requirement from a regulator or CFO and turn it into something engineers can actually build.
• You're comfortable driving alignment with a CTO and CFO directly — no product director needed as a go-between.
• You understand how money moves: settlement, reconciliation, correspondent banking, SEPA, SWIFT — well enough to spot when something is wrong.
• You figure things out yourself. You read the docs, you call the counterparties, you don't wait to be briefed.
• You think in flows, not features — you see the end-to-end journey of funds, not a backlog of disconnected tickets.

Our Mission and Vision

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we're on a bold path: to become the #1 payments orchestration platform in the world.

We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That's exactly the kind of teammates we want on board.

Solidgate is part of Endeavor — a global community of the world's most impactful entrepreneurs. We're proud to be the first payment orchestrator from Europe to join — and to share our expertise within a network of outstanding global companies.

About the Team and Role

You'll join the Connectivity team — the team responsible for the user-facing services that serve as the entry point into Solidgate's payment system. It's hard to overstate how critical these services are: every millisecond of load time and every suboptimal step directly affects merchant conversion and company GMV, which means the work demands technical excellence and continuous improvement.

The team owns Payment Form and Payment Link (products that let merchants connect to Solidgate and start accepting payments within hours), e-commerce integrations such as adapters for platforms like Shopify, SDKs that make technical integration intuitive and seamless, and Merchant Config, an internal service that stores data critical to payment processing. These products are in a stage of active development, aimed at giving merchants an even more intuitive integration experience along with more room for customization, testing, and support. The strategic goal is to make integrating with Solidgate's payment system the most reliable, extensible, and developer-friendly experience on the market.

Your team — Tech Lead, 2 Backend Software Engineers, 2 Frontend Software Engineers, AQA Engineer, Product Analyst, and Product Manager.

You'll be working across key components including Payment Form/Payment Link, e-commerce integrations, SDKs, and Merchant Config — with a small team where each engineer directly influences key technical and product decisions, metrics, and ultimately the company's financial and reputational outcomes.

You're a great fit if you have:

• 5+ years of experience with Go or another statically typed language (with a willingness to move to Go)
• Experience with SQL (PostgreSQL) and distributed systems
• Experience designing reliable, scalable, high-load systems
• Experience with cloud environments (AWS/GCP)
