Jobs at Djinni

We are building a sports booking platform that connects sports clubs, trainers and studios with people looking for sports activities.

Our platform helps sports businesses manage their services, schedules, customers and bookings, while allowing users to easily discover and book sports activities.

We are an early-stage startup looking for a creative, proactive and technology-minded marketer who can help us grow our platform, attract users and sports partners, and make our product more visible.

What You Will Do

• Create marketing strategies: Find creative and unconventional ways to promote our platform and attract sports clubs and users.
• Produce engaging content: Develop ideas, film and edit short promotional videos, create social media content and advertising materials.
• Launch advertising campaigns: Plan, execute and optimize campaigns on Meta, Google, TikTok and other relevant channels.
• Explore growth opportunities: Research competitors, trends, communities, influencers, partnerships and new acquisition channels.
• Improve our product: Explore our application in depth, identify usability issues and propose improvements based on research and user feedback.
• Experiment and analyze: Test different marketing approaches, measure results and continuously improve what works.

• Take initiative: Independently generate ideas, propose campaigns and turn them into real experiments.

   

Who We Are Looking For

• A creative thinker who enjoys generating ideas and bringing them to life.
• Someone proactive, independent and comfortable working in an early-stage startup.
• Experience in digital marketing, growth marketing, content creation or similar fields.
• Ability to create and edit engaging short-form video content.
• Familiarity with social media advertising platforms and campaign management.
• Strong digital skills and curiosity about technology, applications and user experience.
• An analytical mindset — someone who wants to understand why something works or doesn't.
• Someone who can research a product, identify opportunities and suggest practical improvements.
• Strong communication and organizational skills.

Experience with sports, fitness, mobile applications, SaaS or startups is a plus, but not required.

What Makes This Role Different

We are not looking for someone who simply posts on social media or follows a predefined marketing plan.

We want someone who asks questions like:

• How can we make our app stand out?
• What creative campaign could attract our first 1,000 users?
• How can we convince sports clubs to join the platform?
• What would make people share our app with their friends?
• Why do users leave the app without booking?
• What could we improve in the product to make it easier to use?
• What marketing ideas can we test with a small budget?

You will work directly with the founders and product team, with the freedom to experiment, influence the product and help shape our growth strategy.

Why Join Us?

• Opportunity to help build a new sports technology platform from an early stage.
• Freedom to propose ideas and execute creative experiments.
• Direct influence on marketing strategy, user growth and product development.
• Close collaboration with founders and developers.
• A dynamic environment with room to grow professionally.

If you enjoy creativity, digital marketing, technology and building something from zero, we'd love to hear from you.

To apply, send us your CV, portfolio or examples of campaigns and creative projects you've worked on. We're particularly interested in seeing what you've actually created.

We are building a distributed GPU-compute marketplace. Buyers launch GPU workloads and inference deployments. Provider nodes run workloads through a Go control plane and a Linux-based Rust agent.

We are hiring a Senior Go Backend Engineer to own correctness-critical backend systems: job lifecycle, placement, billing, provider operations, and API contracts.

You will work directly with the CTO on a system where transactional correctness matters. A duplicate request, failed worker, agent restart, or incomplete usage record must not create free compute, double-charge a buyer, or release a GPU while work is still running.

What you will own

- Go services and APIs for buyers, providers, operators, and agents.

- PostgreSQL data models, migrations, transactions, locking, and query performance.

- Job lifecycle and placement across GPU provider nodes.

- Prepaid billing, reservations, settlement, refunds, reconciliation, and audit records.

- Background workers, idempotent retries, and recovery after partial failure.

- Secure agent APIs using mTLS and signed short-lived credentials.

- Tests that prove correctness under retries, concurrent requests, and failure cases.

- Clear API contracts, OpenAPI documentation, metrics, and operational diagnostics.

Our stack

- Go backend services.

- PostgreSQL, Redis, NATS, and JetStream.

- Rust agent on Linux GPU hosts.

- Kubernetes, Prometheus, Grafana, and GCP.

- Next.js frontend.

What we need

- 5+ years of backend engineering experience.

- Strong production Go experience.

- Strong PostgreSQL experience, including transactions, indexes, migrations, and query analysis.

- Experience building distributed or event-driven systems.

- Experience designing idempotent APIs and handling retries or partial failures.

- Strong testing discipline, including integration tests.

- Experience with Redis, message queues, or NATS.

- Ability to reason clearly about correctness, security, and money movement.

- Clear written communication and ownership from design through production support.

Nice to have

- Payments, billing, ledger, marketplace, fintech, or accounting-system experience.

- Kubernetes, GCP, and production observability experience.

- mTLS, cryptography, signed credentials, or security-sensitive APIs.

- Rust, Linux, GPU infrastructure, or distributed-systems operations.

This is a hands-on senior role. You will ship production Go code, review critical changes, investigate failures, and improve the system so that it stays correct under real production conditions.

We are building a distributed GPU-compute marketplace. Buyers launch GPU workloads and inference deployments. Provider nodes run those workloads through a Go control plane and a Linux-based Rust agent.

We are hiring a senior Site Reliability Engineer to own production reliability as we move from validated paid-path drills to operating a real production fleet.

You will work directly with the CTO and will have broad ownership of production operations, deployment safety, observability, and incident response.

What you will own:

- Production deployments, rollback plans, and safe database migrations.

- Monitoring, alerting, dashboards, and operational runbooks.

- Incident response, post-incident analysis, and permanent reliability improvements.

- Infrastructure as code, secrets management, access controls, backups, and recovery drills.

- Reliability of the backend, workers, gateway, databases, and provider-node fleet.

- Fleet installation and validation for GPU providers.

- Capacity, availability, and cost visibility for production infrastructure.

- Engineering automation that removes recurring operational work.

Our stack

- Go backend services.

- Rust agent running on Linux GPU hosts.

- PostgreSQL, Redis, NATS and JetStream.

- Kubernetes, containers, gVisor, Prometheus, Grafana, and Alertmanager.

- Terraform and Ansible.

- GCP and bare-metal GPU infrastructure.

What we need

- 6+ years operating production infrastructure or distributed systems.

- Strong Linux and networking troubleshooting skills.

- Production Kubernetes experience.

- Experience with Terraform or another infrastructure-as-code system.

- Experience with Prometheus, Grafana, logs, alerting, and incident response.

- Experience operating PostgreSQL, Redis, queues, or other stateful production systems.

- Strong scripting or programming ability in Go, Python, or Bash.

- A track record of building reliable systems, not only responding to tickets.

- Clear written communication and comfort owning an incident from detection through prevention.

Nice to have

- GCP or another major cloud platform.

- Bare-metal, GPU, NVIDIA, or high-performance-compute operations.

- mTLS, secrets management, security hardening, or compliance work.

- Experience with Rust services or agents.

- Experience supporting a paid, multi-tenant product.

This is a hands-on senior role. You will write automation, improve production systems, participate in on-call, and help shape how our company operates as it grows.

About the Role

LiftIQ is looking for a Senior Analytics Engineer / BI Product Engineer to build the
reporting and analytics products our teams use to run the business.
This is not a traditional BI role where stakeholders provide specifications and you simply
build dashboards. We need someone who can understand the underlying business
problem, determine what users actually need, and turn ambiguous requests into accurate,
actionable analytics.

Often, the best solution will be different from what was originally requested. You should be
comfortable challenging requirements, identifying insights users did not know to ask for,
and designing reports that help people make decisions—not simply giving them more data.
This is also a highly technical full-stack analytics role that blends analytics engineering
with BI product engineering. You will work across BigQuery, dbt, TypeScript, Next.js, and
React, using Claude Code extensively to accelerate development.

Data correctness is critical. Wrong numbers are worse than crashes.
You will own the accuracy, reliability, and usability of LiftIQ’s reporting products
end‑to‑end—from data modeling and metric definitions to dashboard experience and
permissions.

What You’ll Do
• Work directly with stakeholders to understand business questions and translate
them into useful analytics products.
• Design metrics, reports, dashboards, and visualizations that surface actionable
insights.
• Write sophisticated BigQuery SQL and build/extend dbt models,data marts and
dimensional models (facts, dimensions, semantic layers)
• Reconcile reporting against source systems and investigate data discrepancies.
• Build dashboards end-to-end across the data layer, semantic layer, application
layer, permissions, and automated tests.
• Use Claude Code heavily while maintaining ownership of the underlying
architecture, logic, and data correctness.
• Protect sensitive financial and compensation data through rigorous server-side
access controls.
• Write automated tests for metrics, business rules, and permissions.
• Document business logic, metric definitions, and data models to ensure clarity and
consistency across teams
What We’re Looking For

• Essential
  Exceptional SQL skills
• Deep experience with analytical SQL, including complex joins, window functions,
• attribution, aggregation, data grain, reconciliation, and performance. BigQuery experience
• is strongly preferred.
• Strong analytical and business judgment
• You can understand what decision a stakeholder is trying to make, determine which
• metrics matter, and design something more useful than simply fulfilling the original
• request.
• Strong requirements-gathering skills
• You are comfortable working directly with business users, asking the right questions,
• understanding unfamiliar processes, and turning ambiguity into a clear solution.
• dbt experience
• Experience using dbt in a high-scale production data environment. Experience with
• dimensional modeling, semantic layers, and metric governance.
• Data skepticism
• You instinctively validate, reconcile, spot-check, and investigate. You should be
• uncomfortable shipping a number you cannot explain.
• Testing discipline
• Experience building testable analytics logic and automated tests for metrics and business
• rules. Experience with version control, PR hygiene, and modular analytics engineering
• practices.

• English: strong working proficiency (B2+), with the ability to communicate directly with business stakeholders and gather requirements.

   

Nice to Have
• Performance or affiliate marketing experience, including CPL, CPA, EPC, ROAS, and
media-buying economics
• Experience with platforms such as Everflow, Ringba, RedTrack, Voluum,
LeadProsper, or HubSpot
• GCP / Cloud Run / Cloud Scheduler / Cloud Build
• Python ETL and API integrations
• Payroll or commission systems experience
• Claude API or other LLM application development
• Interactive data visualization
• Playwright / E2E testing
Tech Stack
Data: BigQuery, dbt, Python ETL, Google Sheets
Application: Next.js 14, TypeScript, React, Tailwind, NextAuth, Neon Postgres
AI: Claude Code, Claude API
Testing: Vitest
Infrastructure: GCP, Cloud Run, Cloud Scheduler, Cloud Build, Docker
What Success Looks Like
A strong person in this role becomes someone the business brings problems, not
dashboard specifications.
If someone says, “I need to understand why this buyer’s margins dropped,” you should be
able to understand the business context, interrogate the data, identify the relevant metrics
and potential causes, and build something that makes the answer clear.

You should be equally comfortable debugging a subtle SQL grain issue, talking with a
stakeholder about how their business works, and using Claude Code to turn the resulting
solution into a production dashboard.

This is a full-stack analytics role, but the hardest part of the job is data correctness,
modeling discipline, and analytical judgment—not frontend development.
Success also means stakeholders trust your numbers without hesitation, dashboards
become decision tools rather than data dumps, and metric definitions remain consistent
across teams.

About Our Client

Our client is a leading enterprise data platform company building an open, high- performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role

We are looking for a Middle Software Engineer (1.5–3.5 years of experience) to join the sustaining engineering team for the data catalog and enterprise data management layer of a large-scale lakehouse platform — the services that automate data ingestion and optimize Apache Iceberg tables for existing customers. The team's mandate is to keep these services running reliably for current clients: investigating and fixing customer- reported issues, resolving defects, addressing performance regressions, and keeping dependencies and security patches current. This is a maintenance and support role, not a feature-development role.

This is a backend Java role in a multithreaded, distributed environment where stability and availability for production customers are the baseline expectations. You will work with hands-on mentorship from senior engineers and in daily collaboration with US-based engineering leads and support teams.

Responsibilities

• Investigate, reproduce, and fix customer-reported issues and defects in the catalog and data-management services (Java)
• Diagnose production problems from logs, metrics, and thread or heap dumps, and work with support teams and solution architects on customer escalations
• Address performance regressions and stability issues in multithreaded, distributed services
• Keep the services current: dependency and library upgrades, security patches, and compatibility fixes
• Write regression tests and small supportability improvements (logging, metrics, diagnostics) so issues are easier to catch and triage next time
• Take part in code reviews and follow the team's release and hotfix process
• Track and apply relevant upstream fixes from the Apache Foundation open-source projects used by the platform

• Communicate status, root causes, and blockers clearly in daily syncs with US-based engineering leads

   

Required Qualifications

• B.S. or M.S. in Computer Science or a related field
• 1.5–3.5 years of professional software engineering experience, preferably in backend or data-intensive systems
• Strong Java programming skills: solid command of the language, the JVM ecosystem, and standard tooling (Maven or Gradle, JUnit)
• Comfortable debugging and supporting production systems — reading logs and stack traces, reproducing issues, and finding root causes
• Good grounding in data structures and algorithms
• Working knowledge of multithreaded and asynchronous programming in Java (java.util.concurrent, executors, futures) and the motivation to go deeper
• Care for engineering quality — tests, code reviews, and an understanding of why availability, resiliency, and zero-downtime upgrades matter
• Comfort with a fast-moving environment, ownership of your work, and an eagerness to learn from and be mentored by senior teammates
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team

• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

   

Desired Skills

• C++ experience — reading or writing performance-sensitive native code
• Exposure to database internals or query planning
• Familiarity with distributed systems concepts: concurrency control, data replication, storage systems
• Apache Iceberg or other open table formats (Delta Lake, Hudi)
• Messaging systems: Kafka, NATS, or cloud pub/sub services

• Contributions to open-source projects (Apache projects especially valued)

   

Details

Engagement: Long-term contract

Location: Europe (EU / EEA / UK), remote

Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team
