Location: Tbilisi, Georgia; Belgrade, Serbia; Nicosia, Cyprus Workplace: remote About the team We’re the AI & Automation Engineering team. Our mission is to make life easier for every internal team through automation, from standalone tools to Operational Hub, the unified platform we’re building to house all the automation tools each department needs. We work directly with Growth, Strategy & Planning, Client Service, Operations, and Data & Solutions (among others), so most of what you build is used by the people you work with every day. The team today is small: a Product Manager, a Full-Stack Engineer, and an AI Implementation Engineer. But the company is growing very fast, and so is our team. About the role We’re looking for a Middle AI Implementation Engineer who thrives at the intersection of automation, AI-assisted development, and practical tool-building. You’ll work alongside our existing engineers to design, build, and maintain the internal tools and automated workflows that power day-to-day operations across the company. The work is hands-on and fast-moving: you’ll turn business needs into working solutions using n8n, LLM APIs (Claude, OpenAI), and AI-assisted development tools like Replit and Claude Code. If you build with AI, want real ownership over features, and want to work closely with the people who use what you build, this is the role for you. Responsibilities Design, build, and maintain n8n workflows that automate internal business processes. Troubleshoot and improve existing automations to keep them reliable, efficient, and easy to maintain. Develop and launch lightweight internal tools using AI-assisted development tools such as Claude Code and Replit. Integrate systems and services through APIs and webhooks, including LLM APIs such as Claude and OpenAI. Work directly with internal stakeholders to understand their needs and translate them into practical solutions. Test tools and workflows, gather user feedback, and deliver improvements as business needs evolve. Contribute new features to the team’s Operational Hub and collaborate with engineers on technical decisions. Take ownership of assigned projects, from requirements gathering through launch and ongoing support. 2+ years of professional experience in QA (preferred), analytics, or project management. Hands-on programming skills are also welcome. Hands-on experience building, debugging, and maintaining workflows in n8n or Make.com. Ability to build and ship functional applications using AI-assisted development tools such as Claude Code, Replit, Cursor, or similar. A working understanding of APIs, webhooks, and data flows, with the ability to troubleshoot integration issues. Basic proficiency in SQL, ideally BigQuery, including reading and working with structured data. Strong communication and stakeholder management skills, with the ability to collaborate with technical and non-technical teams. Ability to understand business processes, clarify requirements, and translate them into practical tools and automations. A proactive approach to problem-solving, willingness to learn, and ownership of your work. Nice to have Experience with Google APIs, particularly Sheets, Drive, and Calendar. Familiarity with Clerk or similar authentication and authorization tools. Knowledge of React or basic frontend development. Experience integrating Slack, Asana, HubSpot, or similar business tools. Experience in AdTech or MarTech. Portfolio If we move forward after the initial HR interview, we’ll ask you to share a portfolio of tools or automations you’ve delivered. Please highlight their measurable business impact and explain your personal contribution to each project.

Tripledot’s guiding principle is that when people love what they do, what they do will be loved by others. We’re building a company we’re proud of. One filled with driven, incredibly smart and detail-orientated people, who LOVE making games. Our ambition is to be the most successful games company in the world, and we’re just getting started. Role Overview Join Tripledot Studios as a Senior Machine Learning Engineer working on dynamic pricing and recommender systems use cases in our games. The work involves tabular machine learning, including neural networks and approaches such as gradient-boosted decision trees. You'll focus on understanding the data, developing features and improving the models, rather than primarily owning production deployment. You'll work toward defined near-term ML targetds, collaborating with the monetization team and game product teams to plan A/B tests. Over the longer term, you'll work with those teams to translate product and monetization requirements into ML objectives. You'll start by learning the project and its business goals. Within the first three months, we'd expect you to contribute to the training pipeline and investigate features and model issues. By around six months, the aim is for you to take a more proactive role in setting the model's direction. Key Responsibilities Build and improve training pipelines for dynamic pricing and recommender system models, from feature and label design through training, tuning and offline evaluation of tabular models such as neural networks and gradient-boosted trees. Monitor model performance once models are live across games and products. Investigate data and concept drift, including shifts tied to new titles, client versions or user behaviour, and make models easier to extend to another product. Diagnose missed model outcomes across the training pipeline, business logic and underlying data, then work through the improvements needed to restore model quality. Work with monetization and product colleagues to connect model decisions to revenue and player outcomes, and help plan the A/B tests that inform what ships. As you get up to speed, identify gaps in the team's understanding of the models and propose improvements to their direction. Required Skills, Knowledge and Expertise Hands-on training and evaluation of tabular models, using neural networks or gradient-boosted trees. Experience with PyTorch, PyTorch Lightning, TensorFlow, XGBoost, CatBoost or scikit-learn could all be relevant; no single framework is required. Experience designing features and labels, choosing metrics for the decision a model makes and judging when offline results warrant an A/B test. Proficiency in SQL and the ability to write efficient queries to extract, manipulate and aggregate data from relational databases. An investigative approach to incomplete data and longer-term requirements that need clarification. The ability to explain model results to monetization and product partners in terms of revenue and player outcomes. Experience in ad tech, recommender systems or online marketplaces would be useful, as would experience with production APIs or deploying ML models. Experience with the Ray framework would also be a plus. None of these is required for the role. Uses AI-assisted development tools, including code assistants and LLM-based copilots, to accelerate implementation, debugging and iteration of machine learning systems while maintaining production-quality standards. Critically reviews and validates AI-generated code, model implementations and infrastructure configurations for reliability, correctness and maintainability, and explores AI-powered approaches to improve developer productivity or ML platform capability.

Location: Remote - Europe Workplace: Hybrid ABOUT CONSENSYS Consensys Incorporated is an independent blockchain infrastructure company, spun out of Consensys Software Inc. — one of the world's leading blockchain technology companies and the primary development organization behind the Ethereum ecosystem. We build and operate neutral, institutional-grade blockchain infrastructure that connects banks, asset managers, custodians, and financial market infrastructures to digital asset networks, meeting the non-negotiable standards of institutional finance: privacy, scalability, resilience, security, and regulatory readiness. Headquartered in Miami, Florida, and operating across the US, Europe, and Australia, Consensys Incorporated launched as an independent entity in September 2026 and is building the team to match its ambition. WHY THIS ROLE EXISTS We build and operate blockchain infrastructure for financial market infrastructure — settlement, custody and clearing institutions who put real value on the networks we run. We have signed clients with production dates this quarter, a platform that has to stand up on its own for the first time, and an engineering organization that has just been through a leadership transition. You are the engineering leader for that organization — the person who owns what we've committed to ships, and who the engineers look to when a technical decision needs making. WHAT YOU'LL OWN - The delivery organization — core engineering (sequencer, node and backend services), smart contracts, and infrastructure/DevOps. - Client delivery against contractual commitments. Several institutional programs are in flight with production dates between now and Q1, each with availability, latency and evidence requirements written into the contract. Availability definitions, maintenance windows, DR, incident process and the proof behind them are yours. System reliability engineering and on-call rota included. - Operating production networks — including a public mainnet run under an arm's-length managed-service agreement, alongside sovereign and permissioned networks for clients. - Work with the Security Lead to help set security standards for partners, clients and internal systems. - The technical roadmap and its sequencing — working with Product and Sales to define what we build, what we buy, what we say no to, and the honest version of when. - Completing the separation from our former parent. Observability, deployment tooling, identity and infrastructure-as-code all have to be rebuilt or properly handed over, under a live clock. - Engineering standards and the release process — how we test, how we ship, how we roll back, how we review, and how we maintain. - Being a credible technical voice with clients. Our buyers are institutional. They will ask you hard questions about resilience, custody of keys, and what happens at 3am, and they will judge the company by the answer. - Leadership and people management — hire, lead, mentor, and develop engineering managers and team leads; foster a remote-first, high-performing, collaborative engineering culture; support performance management and career development; and liaise closely with team leads to coordinate priorities, dependencies, resourcing, and delivery across engineering. - Contribute to major architecture or investment proposals. - Meet customers or partners where engineering involvement is valuable. - Managing and integrating company wide objectives into engineering team based measurable objective key results (OKRs) and communicating on these objectives to the organization. - Engineering operating model — who owns what, who decides, and what escalates to you. You set decision rights with Product, Sales and Protocols so a stuck call does not sit in a meeting for two weeks. - Delegation. Delivery, incidents and most design calls sit with engineering managers and tech leads. You are the exception path and the person who builds those managers, not doing every estimate and every review. - How the organization uses AI in the actual work. You use it yourself every day and you make it the default for the teams, with the same bar we already apply to human-written code. This is practice, not an “AI strategy” slide. - Cost management. You will strive to reduce operating costs wherever possible without reducing quality or productivity. One area sits outside this role, although your work will align closely with it: - Core protocols (Besu, Teku and related clients) sit with our Head of Protocols, reporting to the CEO. Some of your delivery dates depend on their commitments; that relationship is a partnership, not a reporting line. WHAT WE ARE LOOKING FOR - Deep Ethereum and EVM experience. - Has run an engineering team of 20+ across multiple teams, as a leader of leaders — and has done it at this company stage. - Has owned production systems under contractual SLAs for demanding customers, and has personally been accountable for an outage in front of one. - Deeply technical. You don't need to be the best engineer here, but you need to earn the respect of people who are — challenge a design, know when an estimate is optimistic. - Distributed-systems depth. Blockchain experience is a real advantage; strong infrastructure and backend leaders from high-integrity domains (payments, exchanges, market infrastructure) will be taken seriously. - Has hired well and retained people through a hard period. - Someone with sound technical judgment, strategic thinking, commercial awareness, and strong prioritization skills. - Direct. This team has a low tolerance for polish over substance. Say the hard thing early, and say it kindly, more light, less heat. - People-first leader — empathetic, approachable, and committed to mentoring and developing others. - Strong communicator — builds trust and communicates clearly across engineering and the wider business. - Collaborative — works closely with team leads to align priorities, coordinate dependencies, and keep teams moving together. - High emotional intelligence — self-aware, thoughtful, and comfortable navigating difficult conversations and change. - Coach and multiplier — develops strong leaders, delegates effectively, and builds high-performing, autonomous teams. - Pragmatic and organized — brings clarity and structure without unnecessary process. USEFUL, NOT REQUIRED - L2 or ZK-rollup architecture. - Regulated financial infrastructure — audit, change control, evidence, SOC 2 / ISO 27001. - Experience of a carve-out, separation or post-acquisition integration. WHAT THIS ROLE IS NOT - Not a box-checker, don’t add process for process sake. - Someone who does not challenge or seek clarity. - Someone who does not seek to understand why and what the value is for a task. - Someone who feels like they have to be the loudest voice in the room and does not seek to listen first and leverage the intelligence of others. - Someone who has not had experience managing engineering teams and who feels comfortable being a single IC. - A 100% hands-on engineering role. WORKING AT CONSENSYS We are a fully remote, globally distributed company. We hire the best people wherever they are, work asynchronously, and judge each other on impact rather than hours or location. We offer competitive compensation, meaningful equity, and the chance to work on genuinely open source software at the frontier of web3. Consensys is an equal opportunities employer. We celebrate diversity and are committed to building an inclusive environment for all employees.
