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.

About the role:

The role will involve designing, developing, maintaining, and improving the company's data warehouse, data pipelines, and analytical data models. You will work with high-volume event data from multiple internal and external sources - supporting a growing analytical layer used for operational monitoring and business analytics.

This is not only a maintenance role. We are looking for someone who can take ownership of data solutions end to end, improve data reliability, optimize data flows, support scalable data modeling, and proactively introduce better practices in data engineering, data quality, and data warehousing.

Requirements:
 

• 4+ years of experience as a Data Engineer, Analytics Engineer, BI Engineer, or similar role.
• Advanced SQL skills and strong experience working with large datasets.
• Strong experience with BigQuery or similar cloud data warehouses; experience with Google Cloud 
• Experience designing, building, and maintaining scalable ETL / ELT pipelines.
• Experience with dbt or a similar data transformation framework.
• Experience with orchestration tools such as Apache Airflow, Prefect, Dagster, or similar.
• Experience building data quality checks, validation rules, monitoring, and troubleshooting processes.
• Experience optimizing data processing, query performance, and warehouse costs.
• Ability to identify root causes of data issues and propose practical, scalable improvements.
• Ability to create and maintain documentation for data flows, models, dependencies, and known limitations.
• Strong end-to-end ownership of data solutions.
• Ability to translate analytical and business needs into reliable technical data solutions.
• Detail-oriented mindset and high standards for data reliability.
• English level B1-B2 or higher.

Nice to have

• Experience integrating and maintaining data from third-party platforms such as marketing systems, CRM tools, tracking platforms, or attribution systems.
• Familiarity with BI/reporting environments such as Looker Studio/Tableau/Power BI or similar.
• Experience designing or maintaining pipelines for high-volume event-level data, logs, or time-series datasets.
• Experience with Git and version control for data pipelines, SQL models, or data projects.
• Experience with Python

Responsibilities:

• Design, develop, maintain, and improve scalable data warehouse solutions and ETL / ELT pipelines.
• Work with high-volume data from APIs, third-party platforms, event data, manual imports, and internal sources.
• Ensure key analytical datasets are updated correctly, on time, and with clear ownership.
• Improve pipeline reliability, monitoring, error handling, query performance, and warehouse costs.
• Build and maintain data quality checks, validation rules, and monitoring processes.
• Detect and investigate missing, duplicated, delayed, inconsistent, or incorrect data.
• Identify root causes of data issues and implement controls to prevent recurring problems.
• Ensure data is reliable, consistent, complete, and ready for reporting and analytics.
• Define and apply standards for table structure, naming conventions, joins, keys, metric logic, and documentation.
• Support clear data layers: raw, staging, analytical, and business-ready datasets.
• Standardize similar datasets and reduce duplicated or inconsistent transformation logic.
• Work closely with Business Analytics to understand analytical needs and data blockers.
• Translate analytical and business requirements into technical data structures and pipeline improvements.
• Support BI and reporting needs by ensuring datasets are reliable, consistent, and well-documented.
• Share best practices, provide technical guidance, and proactively introduce improvements in data engineering and warehousing.

What it means to be part of our Team:
 

• Multinational and intercultural experience
• Corporate library
• A world-class team to work with
• Growth opportunities
• Cutting-edge frameworks and technologies
• Competitive salary
• Plenty of engaging team-building and social events

• 21 paid vacation days & 14 paid sick leaves;
• Cozy office in Warsaw, Kyiv available for you whenever you need it
• Coffee, tea, Red Bull, sweets, fruits, and more snacks

💌 Interested?

We’re always on the lookout for passionate, driven, and curious people to join our team.If that sounds like you — we’d love to hear from you!

CreditBooster.ai's mission is to help every American understand, build, and own their credit. We're an AI-native credit improvement platform, live on the App Store and Google Play, with paying customers and a small remote team across the US and Europe.
 

About the role

We're hiring for a mindset more than for a stack: the engineer who treats a piece of the product as theirs and holds themselves to whether it actually works for the person using it.

That means ownership that follows the experience wherever it lives. A flow starts on a mobile screen, continues on the web, and runs through the API behind both, and we want someone who goes all the way down rather than stopping at a repo boundary. That's usually where the quality of an experience is won or lost.

AI is not a slogan here, it's how we build. Our designer shipped the referral page that's live in production today working with an agent. Our CPO built one of our web apps the same way. The standard we hold ourselves to is not handing a ticket to an agent and approving the result: you plan with it, read the plan properly, push back, iterate, and stay responsible for what ships.

We move fast and we're deliberately not over-gated, even in fintech. Freedom to move, judged on results.

Fully remote, with morning Chicago overlap for standups and demos. Our working overlap is only about four hours a day, so being genuinely effective asynchronously matters here. We'd rather say that plainly than have you discover it in month two.
 

Responsibilities

• Own a product surface end to end: the mobile screen, the web equivalent, and the API behind both, with accountability for whether it works and not just for whether it shipped
• Ship across React Native (Expo) on iOS and Android, our web app, and our Astro landing site
• Cross the boundary rather than filing a ticket at it: Node.js, Fastify, TypeScript, and PostgreSQL are within reach when the surface you own needs them
• Hold the quality bar on what you own, from symptom to root cause to a fix you can prove held
• Use Claude Code, MCP servers, and your own agents to compress engineering work that used to take days into hours, while staying responsible for everything that merges
• Manage releases across App Store and Google Play: EAS builds, rollouts, OTA updates
   

The kind of work you'll see in your first sprint

• Taking one user-facing flow end to end and coming back with your own read on where it should be better, across mobile, web, and API
• A recurring production bug traced to root cause rather than patched at the symptom
• A view on the React Native versus native question, argued from the codebase rather than from preference
   

What we're looking for

• You've owned something, not just contributed to it. You can point at a surface in a product and say it was yours, describe what would have gone wrong without you, and separate what you owned from what your team delivered. This is the single thing we're screening hardest for
• You work across mobile and web. React Native is the centre of gravity, but a surface that stops at the repo boundary isn't owned. You're comfortable in a web codebase and not helpless behind an API
• You're AI-native in how you build. Claude Code or an equivalent agentic CLI is part of your daily workflow. You've built your own skills, agents, or MCP servers that automate real engineering work. You see agents as your primary collaborator, and you can also tell us about a time one was confidently wrong and how you caught it
• You debug for real. You go symptom to root cause to verification, and you know the difference between a bug that stopped reproducing and a bug that got fixed
• You're not attached to a framework as an identity. We may move to Swift. We may not. Either way we want someone who argues it from the codebase and then commits
• You ship without waiting for a spec. Often there's a problem and an owner, not a written specification
   

You may be a good fit if you have

• 4+ years building product software, with real React Native (Expo strongly preferred) shipped to both the App Store and Google Play
• A product area you owned in production. Be ready to walk us through it: what it was supposed to do, what broke, what you changed, and how you knew things got better
• Real web experience alongside mobile: React or a modern web framework, in production
• TypeScript strict-mode discipline
• Enough Node.js and SQL fluency to fix the endpoint behind your own screen
• Effective written communication in English (B2 or higher). Our team works in Russian and Ukrainian internally, but Linear, code, and customer-facing copy are English
   

Bonus

Native iOS in Swift or SwiftUI. Fintech, lending, KYC, or other regulated-domain work. Expo EAS pipeline ownership and store release experience. Astro or comparable modern web frameworks. A public Claude Code skill, MCP server, or contribution to an open-source agent harness. Founding engineer or first-few-hires experience at a small company, where owning the whole thing was the default.

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.
