About Kooltra

Kooltra is a Canadian fintech company building FX infrastructure and cross-border payment technology for banks and financial institutions. With over a decade in market, we're accelerating our US expansion and shifting toward an AI-first development and delivery model.

AI has changed the economics of writing code. The bottleneck is no longer how fast we can build — it's how confidently we can ship. As AI accelerates the volume and velocity of change across our platform, the systems that verify correctness, catch regressions, and keep production observable become the highest-leverage engineering investment we can make. We're hiring an architect-level platform engineer to own that layer end to end.

The Role

You will design, build, and operate the quality gate system that lets Kooltra ship AI-accelerated code with confidence — in a domain where correctness is non-negotiable. Financial infrastructure doesn't get to "move fast and break things." Your job is to make moving fast and not breaking things a structural property of how we deliver software, rather than a matter of individual discipline.

This is a systems-building role, not a QA role. You won't be writing test cases for other people's features — you'll be architecting the automated, layered verification pipeline that every change flows through, from the first property test to production observability.

Key Responsibilities

• Architect a layered quality gate system spanning the full delivery lifecycle: property-based testing, unit and integration testing, contract testing, UI and end-to-end testing, CI/CD pipeline gates, and production observability
• Champion test-driven development as a design discipline across the engineering organization — and evolve what TDD means when AI agents are writing a growing share of the code
• Establish property-based testing as a first-class practice for our financial domain logic, where invariants (balances reconcile, events replay deterministically, money is never created or destroyed) matter more than example-based cases
• Design and own CI/CD pipelines that act as structured, automated gates — every merge and deploy earns its way to production through verification, not review-by-heroics
• Build the UI and end-to-end test infrastructure that keeps critical user journeys verified continuously, with the reliability and speed engineers actually trust
• Define the observability architecture — metrics, traces, structured logs, SLOs, and alerting — that closes the loop from "it passed the pipeline" to "it's behaving correctly in production"
• Make quality gates AI-native: verification systems that validate AI-generated code at the volume and velocity AI development produces, and that AI agents themselves can invoke, interpret, and respond to
• Set the standards, golden paths, and tooling that make the well-tested path the easiest path for every engineer and every AI agent on the platform
• Instrument and report on delivery health — escaped defects, flake rates, lead time, change failure rate, time to recovery — and drive them in the right direction
• Partner with platform, product, and compliance teams to ensure the verification layer supports auditability and our regulatory obligations

Required Qualifications

• Deep experience designing test architecture and delivery systems in enterprise or B2B SaaS environments — you've built quality systems, not just used them
• Hands-on expertise with property-based testing (e.g., jqwik, Kotest property testing, fast-check, Hypothesis) and a clear view of where it beats example-based testing
• A genuine test-driven development practice and the ability to teach, model, and scale it as a design discipline
• Proven experience building and operating UI / end-to-end test infrastructure (e.g., Playwright, Cypress) that stays fast and non-flaky at scale
• Strong CI/CD architecture experience — designing pipelines as products, with staged gates, ephemeral environments, and deployment strategies like canary or progressive rollout
• Production observability expertise: metrics, distributed tracing, structured logging, SLOs, and alerting (e.g., Prometheus, Grafana, OpenTelemetry, Datadog)
• Proficiency in Kotlin and TypeScript, or deep experience on the JVM with the ability to ramp quickly
• Experience with event-driven architectures (Kafka) and how to test them — contract testing, replay testing, verifying eventual consistency
• Hands-on Kubernetes (EKS) and AWS experience
• Genuine enthusiasm for AI-assisted development — and a clear-eyed view of why it makes rigorous automated verification more important, not less
• Excellent communication skills — this role changes how the whole engineering team works, and that requires influence, not just architecture

Nice-to-Have Qualifications

• Fintech, payments, FX, or treasury operations background — you understand why a rounding error is an incident
• Experience building verification systems for AI-generated code, or evaluation harnesses for LLM-based systems
• Mutation testing experience and opinions on measuring test suite effectiveness beyond coverage
• Formal methods exposure (TLA+, model checking) or design-by-contract experience
• SOC 2 or similar compliance framework familiarity — evidence automation, change management controls
• Track record building internal developer platforms, tooling, or golden paths
• Open-source contributions to testing, CI/CD, or observability tooling

Why This Role Matters

Every company adopting AI development is about to learn the same lesson: generation is cheap, verification is everything. The quality gate layer is what converts AI acceleration from risk into advantage — and at Kooltra, it protects systems that move real money for real financial institutions.

If you believe a great test suite is an act of empathy for every engineer who ships after you, that pipelines should be architected like products, and that AI-first delivery is only as strong as the gates it passes through — we'd love to talk.

• Optimize for the edge – convert and quantize models (TFLite/ONNX/RT-Core) so they run in real time on Raspberry Pi 5 and ARM-based phones.
• Own the ML pipeline – data collection, labeling guidelines, experiment tracking (Weights & Biases / MLflow), automated training, and CI/CD to Kubernetes.
• Collaborate cross-functionally – work with backend, video-encoding, and mobile teams to integrate inference results into our NestJS APIs and Flutter/Angular clients.
• Raise the bar – research state-of-the-art techniques, run ablation studies, author technical specs, and mentor future student interns.

Requirements

• Strong Python (3 yrs+) and deep-learning expertise with TensorFlow and/or PyTorch.
• Solid background in computer vision: convolutional nets, attention mechanisms, spatio-temporal models (e.g., I3D, SlowFast).
• Experience deploying models to mobile or edge hardware (TFLite, Core ML, TensorRT, or similar).
• Familiarity with Docker & Kubernetes workflows for scalable training/inference.
• Proven ability to turn research into production code: at least one project or product in the wild (GitHub, app store, or academic publication).
• Comfortable with version control, code reviews, agile tickets, and writing clear documentation.
• Passion for sports—or at least enough curiosity to spot a backhand winner or a slam-dunk replay!

• English—professional level (our dev team is global).

   

Bonus points

• Experience with video encoding pipelines (FFmpeg, HLS, RTMP) or real-time streaming protocols.
• Knowledge of AWS/GCP services for training at scale (SageMaker, Bedrock, Vertex AI).
• Skills in data annotation tooling or active-learning strategies to shrink labeling budgets.
• Background in satellite or aerial image segmentation, sign-language or face-recognition projects (great analogies to sports CV challenges).

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.

We're building the #1 payment orchestrator in the world — and the names behind us prove it. Clients include Bolt, Ajax, Nova Post, MEGOGO. Trusted by giants like J.P. Morgan. Ranked #2 in the "Employer of the Year 2026" award by Forbes Ukraine.
 

About the Role

Our marketing mission is simple: Solidgate should be everywhere. Every channel. Every conversation. Every feed.

⚡ This role is for a builder — someone who knows that great content doesn't happen on its own, it's created, tested, and refined every single day.

We're looking for a Senior Content Manager who will be the bridge between product, sales, and the market. Someone who turns complex fintech into stories that CPOs and CFOs at target companies actually read. Not a brief executor — a channel owner who plans, decides, and publishes.
 

What you'll own

• Full ownership of the LinkedIn channel — content plan, writing, publishing, and analytics. Your posts land in front of CPOs and CFOs at our target companies.
• Product content: turn feature releases and product updates into blog posts, LinkedIn content, and website copy that actually connects with B2B buyers.
• Stakeholder management: independently extract insights from product, sales, and AM teams — no chasing required. Build bridges so content flows without bottlenecks.
• PR & thought leadership: expert articles, media commentary, and thought leadership content that establishes Solidgate as the go-to voice in payments.
   

You'll be great at this if

• You have 2+ years in B2B/SaaS content marketing and have independently owned a company LinkedIn channel — not just contributed to one.
• Your English is C1+ and you can write product-heavy content that doesn't sound like a manual.
• You don't wait for a detailed brief. You show up with ideas and drive them to publish.
• You have written case studies and product content — not just SEO articles about abstract topics.
• Fintech or payments background? That's a major plus — but deep curiosity and a fast learning curve can get you there too.
   

Why Solidgate?

Real impact. Your LinkedIn post is read by CPOs and CFOs of companies we're closing. Your case study ends up in the sales deck.

True autonomy — you own the channel. Plan, decide, publish — no approval queue for every post.

Speed — minimum bureaucracy. Short feedback cycles. Decisions actually get made.

Fintech depth — go deep into the payments industry alongside a team with 10 years of experience.

Growth path — a clear road to Head of Content or Content Lead at a fintech company with global reach.

About the Role and the Team

Our Platform stream acts as a backbone for product teams, handling the complexities of infrastructure, efficient technical solutions, and development frameworks. This allows product teams to concentrate on what they do best: developing and refining product features and experiences.

⚡ This role is for a builder. You'll take ownership of teams inside our Platform stream — the merchant-facing side of the shared services every other product team and merchant at Solidgate runs on.

Your mentor — Mykola Stasiuk, Senior Product Manager on the Platform stream, who leads the other two, data-oriented teams.

What You Will Own

You'll shape and evolve these core components:

• Auth — authentication, authorization, access management across all admin panels
• Notification system — how merchants and internal teams get informed, reliably
• Audit and Approval Manager — logging and approval workflows that hold up under scrutiny
• File Management — file upload, export, and report generation
• Bulk operations and MCP
• UI Kit — the shared component library other teams build their interfaces on

Why This Is Exciting

• Real leverage — one good decision here moves dozens of teams and every merchant at once, not just your own backlog
• Strong technical culture — you'll work with engineers who think about architecture, not ticket counts
• Fast feedback — ship something, and you'll see how it performs within days, not quarters
• Since the domain is technical, you're working shoulder-to-shoulder with engineers constantly — meaning you build technical depth in a fraction of the time other PMs take
• You shape it, not inherit it — parts of this domain are still being formed, so you decide how it works

You'll be great at this if:

• you have 2+ years in a B2B product — that's what matters, not your title. Whether you're a business analyst, a system analyst, an engineer, a QA engineer, or a PM: if you think like a product person, you're a match.
• you're comfortable enough with APIs and CI/CD that you don't need an engineer to explain the basics
• you bring curiosity, drive, and strong cognitive skills to everything you do
• you're a structured thinker who brings order to ambiguous, cross-team requests
• you find common ground with strong-opinioned engineers without losing your own point of view

Why Join Solidgate?

High-impact role. You're not inheriting a perfect system — you're shaping one.
Great product. We've built a fintech powerhouse that scales fast. Solidgate isn't just an orchestration player — it's the financial infrastructure for modern internet businesses. From subscriptions to chargeback management, fraud prevention, and indirect tax — we've got it covered.
Growth opportunity. Solidgate is scaling rapidly — this role will be a career-defining move.
Top-tier tech team. Work alongside a proven, results-driven engineering team that delivers.

Tomorrow's fintech needs your mindset. Come build it with us.
