We are helping our partner — a fast-growing product company in the iGaming space — find a Middle Java Developer to join their backend team.

This is a product environment where backend engineering directly impacts platform stability, scalability, and business growth.

You won’t just “close tickets.” You’ll work on real systems, real architecture, and real technical challenges.

What this role is really about

You’ll be working on a high-load platform where:

• systems process real-time events;
• performance and reliability matter daily;
• backend services must scale under heavy load;
• technical decisions affect the whole product ecosystem.

The team builds and develops services end-to-end, with a strong engineering mindset and ownership culture.

What you’ll be doing

• Develop and improve backend services.
• Work with microservices architecture.
• Participate in technical discussions and solution design.
• Solve performance and scalability challenges.
• Collaborate closely with developers, QA, and product teams.
• Support and improve existing services while building new functionality.

• gRPC — nice to have.

But more importantly:

• You think beyond tasks.
• You can explain your technical decisions.

• You care about quality, not only delivery speed.

What you get

• Product company environment (not outsourcing).
• Real impact on the product and technical decisions.
• Strong engineering team and mature processes.
• Complex backend challenges and high-load systems.
• Remote work format.
• Fast-growing iGaming product with global scale opportunities.

We are helping our partner — a fast-growing product company in the iGaming space — find a Senior Java Developer to join their backend team.

This is not a “just write code” role.

This is about building systems, making decisions, and owning the result.

What this role is really about

You’ll be working on a high-load casino product, where:

• systems process real-time events
• performance matters
• architecture decisions have real impact

The team builds services from scratch and owns them end-to-end.

What you’ll be doing

• Build new backend services from scratch
• Participate in architectural and technical decisions
• Work with microservices and distributed systems
• Solve complex technical challenges
• Collaborate in a cross-functional team (product / QA / dev)
• Take ownership of what you build — not just tasks

What we’re looking for

• Strong experience with microservices architecture (2+ years)
• Deep understanding of distributed systems
• Hands-on experience with:
  • Spring Boot
  • PostgreSQL

• Real impact on architecture and product
• Strong engineering team
• Fast-paced environment with real challenges
• Remote work

About the project:

Search is changing fast. AI-generated answers are replacing ranked links, and brands that aren't visible inside those answers are simply invisible. This role exists to make sure our clients are inside those answers — not invisible to them. You'll own GEO end-to-end: auditing content for AI retrievability, building entity coverage, shaping how information is structured so language models can extract and cite it reliably. You'll also maintain solid traditional SEO foundations in parallel, because both disciplines are still in play.

A new team member will be in charge of:

• Lead GEO strategy from audit to execution — entity mapping, semantic architecture, and content structuring for AI retrievability
• Shape how content is written and organized so LLMs can extract, surface, and cite it: clear heading hierarchies, modular answer formats, entity-rich copy
• Monitor how models like ChatGPT, Perplexity, and Gemini retrieve and represent brand content — then turn findings into concrete changes
• Run traditional SEO execution in parallel: technical audits, on-page optimization, keyword strategy — keeping the foundation strong as discovery shifts

• Use AI tools (Claude, ChatGPT) actively to test prompts, validate visibility, and pressure-test content across AI search surfaces

   

Does this relate to you?

• Hands-on GEO experience (1 year active GEO practice) — you understand how LLMs source content in practice, not just in theory; prior SEO with active GEO experimentation is fully valid
• Strong SEO fundamentals (3+ years proven SEO): technical audits, on-page optimization, keyword research — you can run this independently
• You know how to structure content for machine readability: semantic hierarchy, extractable answer formats, clean entity coverage
• Solid understanding of what makes content citation-worthy inside generative systems — and what gets ignored
• Comfortable working with AI tools as part of your daily workflow, not just as an experiment

• Link building experience plus especially building off-site authority that feeds both traditional and AI-driven discovery

Join us in building advanced forecasting and optimization capabilities for an energy trading company participating in electricity markets across multiple regions. We are looking for a Data Scientist to own the development of predictive models that directly support our trading team's market decisions. 

This is the first dedicated data science hire on the project. You will establish modeling standards, define best practices, and deliver the work yourself — across the full data science lifecycle: from time series forecasting and price prediction to battery optimization and model governance. The role requires strong technical depth and the ability to engage directly with business stakeholders in a domain where the problems are genuinely hard.

Key Responsibilities

• Design, build, and validate time-series forecasting models for facility load, market demand, and electricity price signals
• Select and tune appropriate modeling approaches (statistical, ML, and deep learning) based on the forecasting horizon, data availability, and accuracy requirements
• Develop and maintain ML pipelines on the Databricks platform using PySpark, MLflow, and Delta Lake
• Partner with domain experts to incorporate market structures, tariff rules, and grid dynamics into model features and evaluation frameworks
• Communicate model performance, assumptions, and limitations to both technical and non-technical stakeholders

Requirements

1. Time-Series Forecasting Expertise
 

You have hands-on experience with a broad range of forecasting methods and know when to reach for each one. This includes classical statistical approaches, gradient boosting methods, and modern deep learning architectures. You understand the practical challenges of time-series work: feature engineering with lags and rolling windows, handling seasonality and regime changes, proper train/validation/test splitting, and avoiding data leakage.

2. Databricks Platform Proficiency
 

You are comfortable working end-to-end in Databricks — from exploratory analysis in notebooks to productionizing models via MLflow tracking, model registry, and scheduled jobs or workflows. Experience with Delta Lake for versioned, audit-friendly data pipelines is a strong asset. Familiarity with Unity Catalog and Databricks Feature Store is a plus.

Nice to Have

• You have worked in or alongside the electricity sector and understand the data and dynamics that drive it
• Experience with graph-based machine learning or graph neural networks (GNNs)
• Experience with probabilistic forecasting (prediction intervals, quantile regression, conformal prediction)
• Exposure to real-time or near-real-time inference pipelines
• Familiarity with weather data integration for load and renewable forecasting
• Familiarity with battery storage optimization or operations research methods for energy asset dispatch
