Jobs at Djinni

We are looking for a High-End Bubble Developer to join our team and work on complex, technically challenging web applications.

We are looking for more than someone who simply knows how to build apps in Bubble. 

The ideal candidate has a strong engineering mindset and deep expertise in database architecture, custom API integrations, Bubble plugin development, performance optimization, and scalable application architecture.
 

You should be comfortable taking ownership of complex technical challenges, making architectural decisions, and building production-ready solutions.

 

We are looking for an experienced Full-Stack developer with strong frontend expertise and comfort working on the backend. Most of the product's traffic comes from organic search, and conversion depends directly on page speed and UX quality, so this role is not just about writing code, but understanding how technical decisions affect business metrics. The split is roughly 70% frontend / 30% backend.

About the project: A ticket search engine for live events that lets users compare offers from multiple sellers in a single platform.

Qualifications: 
● 4+ years of full-stack experience with a clear frontend weight.
● Expert-level Next.js: App Router, React Server Components, caching strategies, SSR/ISR trade-offs. 
● Working Python for backend tasks: REST APIs, data modeling, third-party integrations, etc. 
● Proven track record of measurably improving Core Web Vitals on a real high-traffic product. 
● Strong CSS and UI craft. 
● Experience working autonomously in an async remote team.
● Fluent English, written and spoken.

Nice to have: 
● Background in marketplace / e-commerce / travel / ticketing products. 
● Experience with Elasticsearch, or building search-heavy products more broadly.
● Experience with multi-locale / multi-currency sites.

What you'll be doing: 
● Building and evolving product features in Next.js / React / TypeScript - event pages, search, ticket comparison, checkout handoff. 
● Directly owning Core Web Vitals and TTFB on high-traffic pages. 
● Treating technical SEO as an engineering problem: rendering strategy, structured data, i18n across dozens of countries. 
● Extending backend services and APIs in Python and Node.js that normalize inventory data from dozens of sellers. 
● Working closely with product managers, designers, and other developers.

SignalsAPI finds new clients for recruitment, staffing and outsourcing agencies. We watch job boards and company career pages across hundreds of sources and tell you which companies started hiring this morning — with the decision-makers to contact already attached.

Around ten agencies have bought and used it over the past year, and roughly a quarter of the demos we run convert to paid. The product is built, live and priced publicly, and anyone can use the signal explorer without an account.

What we don't have is enough of the right agencies seeing it. That's the whole job.

Who we sell to

Recruitment and staffing agencies of 5–100 people — the ones chasing client companies, not candidates. The buyer is the owner, the MD, or whoever owns revenue. Price isn't the obstacle at that size, and neither is the product. Attention is.

What you'll do

• Get agency owners and revenue leads to claim their 10 free signals.
• Build the target list yourself: firmographics, the agencies' own hiring activity, communities, whatever works. SignalsAPI is a good tool for it.
• Run one channel experiment at a time. We rank by impact, confidence and ease, start at the top, and drop what doesn't produce.
• Write the outreach, load the sequences, follow the ones that bite.
• No demo call needed to convert — the sample signals are the demo.

What we're looking for

• Someone who executes. We have around twenty strategy documents on file and not one of them reached a customer.
• Written English good enough that a UK agency owner replies to it.
• Comfortable with AI tools. We use them throughout and don't care how you produce work as long as it lands.
• Available during central European business hours.
• What you've done matters more than where you did it. Send the CV, but the answer to the question below is what we read first.

Nice to have

• You've sold to recruitment or staffing agencies, or worked in one.
• You've built a target list from scratch rather than bought one.

How hiring works

1. Apply and answer the question below. It's the only thing we screen on at this stage.
2. If the answer's interesting, a 15-minute call. One call, no panel, often at short notice.
3. Then a short written plan.
4. Then a paid 14-day trial against a target we agree with you before it starts. Real scope, real money.
5. If the trial works, we talk about the job properly.

What we offer

• Fully remote, hours are yours.
• A product that already converts and public pricing — you're not being asked to validate anything.
• Direct access to the two people who run the company. No layers, no committee.

We are looking for a talented Agentic Full stack Engineer (AI-Native Delivery) with 3+ years of commercial full stack experience, to join an established, revenue-generating B2B platform for the materials industry.

This is not a "write code with AI" role — it's an operate AI agents role: decompose work, fan it out to parallel coding agents, verify adversarially, ship across the stack.

JOB REQUIREMENTS:

Must have:

• 3+ years of commercial fullstack development experience (React + Node.js/TypeScript, or Python)
• Hands-on, practical experience directing multiple AI coding agents in parallel — isolated worktrees/branches, adversarial verification of agent output, spec-driven development, and building reusable AI skills/hooks/commands for recurring workflows 
• Working knowledge of PostgreSQL and basic understanding of cloud infrastructure (Terraform/AWS)
• Ability to work fully autonomously and communicate directly with an English-speaking client team without a manager in between
• English — Upper-Intermediate or higher

• Experience in multi-tenant / B2B SaaS platforms
• Familiarity with compliance frameworks (GDPR, SOC 2, ISO 27001)
• Experience building internal tooling for other engineers
• Design-system literacy

Key Responsibilities:

• Full-stack development across the client's platform — from a React component to a Postgres row-level-security policy to a Terraform module
• Cross-boundary root-cause debugging: auth, pagination, dependency conflicts, integration mismatches
• Turning recurring tasks into reusable AI agent skills, hooks, and commands so the next run is faster
• Proving results with concrete evidence — fixtures, payloads, read-back records — rather than relying on a green CI badge alone

PROJECT

Customer: Established, revenue-generating international platform for the materials industry, backed by a large global industrial distribution group.

Type: B2B SaaS / marketplace platform.

Product: The platform serves as a digital backbone for companies across the materials industry — chemicals, polymers, elastomers, rubber — replacing a patchwork of separate CRMs, ERPs, and spreadsheets with one connected system that turns commercial interactions and physical assets into structured, usable data.

Market: Global materials/chemicals industry, client team based in the US.

Stage: Mature, actively growing platform with an established engineering team (not a from-scratch build).

Project team: 3 developers, 2 QA, 1 DevOps on the delivery side, plus a dynamic client-side team. 

Work schedule: Full-time, full remote 

INTERVIEW STAGES:

• 1-st stage — Call with the Recruiter
• 2-nd stage — Interview with the technical specialist and the recruiter

• 3-rd stage —  Interview with the client

   

OUR BENEFITS:

• Projects with modern JS stack (React.js, React Native, Angular, Node.js)
• Strong JavaScript community at the company (90+ developers)
• Work from anywhere (fully remotely or in our office)
• Paid vacations and sick-leaves, additional days-off, relocation bonus

• Work with databases and optimize their performance.
• Develop and maintain REST APIs.

Requirements:

• Strong proficiency in Python.
• Experience designing and developing services and distributed systems.
• Understanding of HTTP, REST APIs, and client-server architecture principles.
• Basic understanding of computer networks and networking protocols.
• Experience integrating with third-party services and APIs.
• Experience working with Docker.
• Proficiency with Git.
• Ability to independently define technical solutions, decompose requirements, and build implementation plans.
• Strong systems thinking and solid engineering practices.

We offer:

• Opportunity to work on cutting-edge defense technologies with real-world impact.
• Professional growth opportunities in a rapidly expanding international company.
• A chance to contribute to products used in mission-critical environments.
• Collaborative team of highly skilled engineers and innovators.
• Flexible and dynamic working environment.
• Competitive compensation package evaluated on a individual basis
• Medical insurance after the probation period.

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.
