Location: Remote | Full-Time 

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 and a growing footprint in North America, we are now accelerating our US expansion and undertaking a fundamental shift toward an AI-first development and delivery model. 

To fuel that shift, we need Platform Engineers to invest in our platform and transform how we implement customers. 

About the Role 

We’re looking for a Platform Engineer who lives and breathes clean architecture and believes that a well-designed domain model is the foundation of everything great in software. You’ll own and evolve our core platform layer—the expressive, domain-driven backbone that powers our suite of financial products and enables third-party applications, services, and UIs to build on top of it with confidence. 

This is a high-leverage role. The platform you shape will be the surface that internal teams, external integrators, and next-generation AI agents interact with. You’ll design APIs and event contracts that are intuitive enough for a developer to pick up in minutes and robust enough to handle complex financial workflows at scale. 

Developer experience is at the heart of this role. You believe that a platform is only as good as how it feels to build on, and you’re obsessed with making the developer journey—from onboarding to production—effortless and delightful. You’ll craft expressive APIs, self-documenting domain models, and tooling that lets internal teams and third-party developers move fast with confidence. 

You’re excited about AI—not as a buzzword, but as a force multiplier. You see the convergence of great developer experience and AI as the next frontier: a platform where AI agents can discover capabilities, reason about domain events, and execute complex financial workflows through the same intuitive surface that human developers use. You want to build an AI-first developer experience—one where the platform is as legible to an autonomous agent as it is to a senior engineer reading the docs for the first time. 

What You’ll Do 

• Iterate and extend an expressive, domain-driven platform layer that serves as the integration surface for internal products, third-party applications, and AI-powered services. 

• Own the end-to-end developer experience on the platform—from SDK design and API ergonomics to documentation, error messages, and onboarding flows—ensuring every touchpoint is intuitive and productive. 

• Pioneer an AI-first developer experience where platform capabilities are discoverable, composable, and structured for consumption by both human developers and AI agents. 

• Define and enforce clean bounded contexts, aggregates, and domain events that model complex financial operations with precision and clarity. 

• Architect event-driven systems using Kafka to enable loose coupling, auditability, and real-time reactivity across the platform. 

• Build and maintain microservices in Kotlin, ensuring each service has a clear domain responsibility and well-defined contracts. 

• Champion test-driven development as a design discipline—not just a quality gate—driving clean, modular, and refactorable code. 

• Design platform APIs, SDKs, and event schemas with a relentless focus on developer experience—self-describing, well-typed, and structured so that AI coding assistants and autonomous agents can reason about and invoke them naturally. 

• Build developer tooling, templates, and golden paths that reduce friction and accelerate time-to-first-integration for both human developers and AI-driven workflows. 

• Operate and optimize services on Kubernetes (EKS) and AWS, making pragmatic infrastructure decisions that balance developer experience with operational reliability. 

• Model and manage data in MongoDB with thoughtful schema design that aligns with domain boundaries and supports evolving query patterns. 

• Collaborate closely with product, compliance, and integration teams to translate complex financial and regulatory requirements into elegant platform abstractions. 

• Continuously evaluate and integrate AI-assisted development tools and patterns into the team’s workflows, raising the bar for what’s possible. 

What You Bring 

• Deep experience building platform layers or shared service foundations in an enterprise or B2B SaaS environment, with a track record of enabling third-party integrations and external developer experiences. 

• Strong command of Domain-Driven Design in practice—bounded contexts, aggregates, domain events, anti-corruption layers—not just theory. 

• Proven ability to design and operate event-driven architectures with Kafka, including schema evolution, exactly-once semantics, and event sourcing patterns. 

• Proficiency in Kotlin and TypeScript, with an emphasis on clean, well-tested, and maintainable code. 

• Hands-on experience with Kubernetes (preferably EKS), containerized microservices, and AWS cloud infrastructure. 

• Solid MongoDB experience including schema design, indexing strategies, and performance optimization aligned with domain models. 

• A test-driven development mindset where tests shape design, not just verify behavior. 

• Strong opinions on clean code and architecture, held loosely and communicated clearly—you make the codebase better every time you touch it. 

• A passion for developer experience as a discipline—you’ve designed APIs, SDKs, or platform tooling with the consumer’s experience as the primary design constraint, and you measure success by how quickly someone can go from zero to productive. 

• Genuine enthusiasm for AI and its potential to transform how platforms are built and consumed. You follow developments in AI agents, function calling, MCP, and autonomous systems and think about how platform design enables or constrains them. You’re energized by the idea of building a platform that AI can use as fluently as a human developer. 

• Excellent communication skills and the ability to articulate complex architectural decisions to both technical and non-technical stakeholders. 

Nice to Have 

• Background in fintech, payments, FX, treasury operations, or regulated financial services. 

• Experience designing APIs or event contracts consumed by AI agents or LLM-based systems, including function calling schemas, tool-use patterns, or MCP server implementations. 

• Track record of building internal developer platforms, developer portals, or self-service tooling that measurably improved developer velocity. 

• Familiarity with compliance frameworks (SOC 2) and how they influence platform design. 

• Contributions to open-source projects or developer tooling. 

• Experience building multi-tenant platforms that serve diverse institutional clients. 

Why This Role Matters 

The platform layer is the highest-leverage code in the company. It’s what makes every product team faster, every integration cleaner, and every AI capability possible. You won’t be building features in isolation—you’ll be shaping the foundation that everything else is built on, and defining what it feels like to build on that foundation. If you believe that great developer experience is an act of empathy, that the best platforms are the ones that disappear into simplicity, and that AI-first design is the future of how platforms are consumed—we’d love to talk.

We're looking for a Lead Python Engineer who will be the key developer on the team - someone who has already designed architecture, not just built against someone else's.

If an e-commerce site goes down, it's inconvenient. This product has to run without failure: if a software glitch shuts down a 50 MW plant, that means direct financial losses and safety risks. Your code moves megawatts, not pixels or shopping carts.

About the company

A European energy company that builds and operates power plants: solar, wind, and industrial-scale battery energy storage systems.

• Our own EMS platform started as an internal tool and is now being turned into a standalone product for any plant owner or energy service company
• The product is at MVP stage

What you'll do

• Take over the platform, together with a small team (a Md Django engineer is already on board)
• Run a technical audit of the MVP
• Design and implement failover for plant connections: reconnect, buffering, redundancy - so telemetry and commands survive unreliable 4G links
• Build agentic pipelines to automate development, testing and deployment, and make Spec-Driven Development a mandatory standard
• Work in two modes: Rapid Validation (shipping lean features to test hypotheses) and Stabilization (hardening what shows traction)
• Do technical pruning: remove dead code and features behind hypotheses that didn't work out
• Set engineering standards: code review, branching, CI gates (ruff, pytest), definition of done. The API has to stay stable for a dispatch center that runs 24/7

Who we're looking for

• 8+ years of production Python experience
• The full stack in production: Django + DRF, FastAPI (Pydantic v2), Celery, PostgreSQL, Redis, Docker / Docker Compose, pytest + CI
• API and system architecture design: service boundaries, contracts, data flows - not only implementing against someone else's design
• RBAC: role models on the principle of least privilege, DRF permissions, object-level access, access enforced consistently across services
• Integrating external APIs behind a caching layer (Redis): cache strategy and invalidation, rate limits, retries/backoff, serving stale data gracefully when the upstream is down
• Failover thinking: reconnect strategies, buffering, health checks, redundancy, graceful degradation over unreliable links
• Spec-Driven Development: contract-first (OpenAPI/Swagger, Pydantic, gRPC), specifications as the source of truth for AI agents
• Agentic pipelines: CrewAI, LangGraph or custom orchestrators, automating engineering workflows
• English B2+

Soft skills

• Product mindset. We need someone who treats the platform as their own product, not as another outsourcing project. Code is a temporary asset until the business model is validated
• Ownership. The result is production, not a PR
• Ability to explain an architectural decision to a non-engineer, and to stay calm during incidents

• Interested in the aviation field:
  You are curious about the aviation industry, care about what you sell, and are ready to learn a complex product domain.
• Fast learner and self-educator:
  You quickly deep dive into new topics, independently search for answers, and adapt fast in complex environments.
• Highly responsible and disciplined:

We are looking for someone who understands automation principles and can evaluate the existing product, propose an appropriate approach, and gradually build automated regression coverage for critical functionality.

Experience with tools such as Playwright, Cypress, Selenium, or similar frameworks is welcome.

What we expect during the first months

During the first 1–3 months, you will receive onboarding and product-specific guidance.

We do not expect you to understand the complete CRM and trading logic immediately.

After the onboarding period, we expect you to:

• Understand the core functionality of the CRM and trading platform
• Independently reproduce most reported issues
• Understand where and how to investigate a problem
• Recognize possible dependencies between different parts of the system
• Maintain regression coverage
• Communicate clearly with developers and the Project Manager
• Become increasingly independent in planning and executing testing

Working conditions

• Fully remote
• Full-time
• Working hours: 09:00–18:00 GMT+3 / 10:00–19:00 GMT+4
• Monday–Friday
• No night or weekend on-call requirements
• Probation/onboarding period: 1–3 months
• Compensation: $1,800–2,500/month, depending on experience and technical level
• Long-term cooperation
• English: Intermediate or higher

Important

We are currently forming a new technical team and establishing development and QA processes.

This role is best suited to someone who is comfortable joining an existing, complex product, learning its logic, asking the right questions during onboarding, and then becoming increasingly independent.

We value reliability, clear communication, ownership, attention to detail, and the ability to investigate a problem instead of simply following a predefined checklist.
