Real ownership. Real impact. Build from day one.

Are you an ambitious graduate ready to tackle complex, real-world challenges at the intersection of data, strategy and tech? 

The Future Leaders Graduate Program – Business Analytics at Picnic is a two-year launchpad for exceptional talents. From day one, you join a business team, own a business topic, and become an expert in your field.

At Picnic, we’re building the future of grocery. Using cutting-edge technology and data-driven innovation, we challenge the status quo and build the world’s smartest, most customer-focused supermarket.
We move fast, think big, and turn bold ideas into tangible impact.

Tricks of the trade

• Lead with ambition: Bring your relentless determination, creativity, and grit. Take the driver’s seat and redefine the grocery shopping experience for millions. You will be expected to think independently, move fast, and deliver results.
• Steep learning curve: Your growth comes from owning real problems, testing your ideas, learning from your mistakes and starting again. You'll blend hands-on training with immediate execution, you’ll move at a pace that accelerates your growth like nowhere else.
• Solve real-life puzzles: Spot opportunities, use tools at the forefront of technology, and own the outcome end to end. Not just making slides, but building the solution yourself.
• Innovate across borders: You’ll collaborate with teams across the Netherlands, Germany, and France, tackling challenges that redefine how Picnic operates at a European scale.
• High-performance environment: You’ll work alongside some of the best teams in analytics and tech, people who set a high bar and expect you to do the same.

From learning to leading

In your first six months, you’ll own a business-critical project from start to finish - supported by mentorship, learning sessions, and regular feedback.
You’ll strengthen your leadership abilities like project management, storytelling, stakeholder communication, giving & receiving feedback, while sharpening your skills in Python, SQL, Excel and PowerPoint.

As your scope grows, so does your responsibility. You might scale your initial project or take on new challenges in the same domain. Either way, the pace is yours to set. 

Where you’ll make an impact

From day one, you’ll be embedded in a business team, taking ownership in one of the following domains:

• Consumer - Drive growth through pricing, supplier strategy, and our market strategy. Think: Shaping our successful market entry into new cities. Your decisions shape how millions of customers experience Picnic.
• Tech - Work at the intersection of product and infrastructure, building scalable systems that power our operations. Think: building software and algorithms our FCAs run on or launch new features in our app used by millions.   
• Logistics - Build the backbone of Picnic: robotic fulfilment, demand forecasting, route optimization across Europe and much more

Your superpowers

You don't wait for permission. You see a problem, build the solution, and bring people with you, before anyone asks. You've probably already started something: a project, a product, a business, an initiative that didn't exist until you made it happen.

More specifically, you:

• Are about to graduate (or recently graduated) a Masters in a quantitative field: e.g., mathematics, econometrics, engineering, or similar
• Have experience in high-performance environments: consulting, fast-growth startups, or competitive internships and know what it means to raise the bar.
• Show an entrepreneurial mindset: you build, improve, and take ownership without being asked
• Think like a builder: hands-on, curious, and driven to challenge the status quo with practical solutions
• You have already gained basic knowledge in PowerPoint, Python, SQL, Excel or alternative coding languages 
• EU citizenship or valid EU working permit required.

Many strong candidates (particularly women) talk themselves out of applying because they don't tick every box. If this excites you and you believe you have what it takes, apply. We only hire when we find the right match. That’s why our selection process is intentionally highly selective.

 Why Picnic?

• Grow as we grow. We’re scaling quickly across countries and millions of customers and this is just the start. Grow your impact as we grow; we invest in your path but the driver's seat is always yours.

FAQ

Do I need a quantitative background? It's a strong advantage, but not a hard requirement. If your internships and projects demonstrate real hands-on ownership and data-driven thinking, we'll consider your application. You do need a Master's degree, basic knowledge of Python or SQL, and relevant work experience.

Does the program include rotations? No, intentionally. We believe depth creates ownership, and ownership creates impact. Rather than rotating across teams, you’ll go deep in one area, build real expertise, and gradually expand your scope as your impact grows. If you have topic preferences, tell us during the process.

In what language should I apply? English. Please include your CV and Master's degree transcript or any other relevant test scores (e.g., GMAT)

What are the long-term opportunities after the program? This program is a fast track into a high-impact career at Picnic, it’s an entry point for a long-term future, not a two-year stopover. 

Career paths here are as varied as the people on them. Some grow vertically, building deep expertise and a team around them as their project expands. Others move laterally - from Commercial to Fulfilment, Distribution to Customer, or wherever their strengths and ambitions take them. What they share is real ownership, real impact, and a career they shaped themselves.

In a nutshell 

Learn while making an impact! This program offers a rare chance to step directly into a real production environment, contributing to systems that operate at scale while strengthening both your technical and behavioral skills. Through the Picnic Tech Academy, you’ll explore topics ranging from Java Clean code to reactive programming and MongoDB, while also developing key capabilities like collaboration and a growth mindset.

The job in short

As a Lead Principal Solution Architect, you set the technical direction on our most strategic banking engagements and make sure ambitious solutions actually ship. You are equally at home in deep architecture reviews with a client’s Chief Architect and in executive conversations with the CTO or COO. With years of designing large web-scale platforms behind you, you hold the full picture of a multi-year transformation without losing the detail. To our implementation teams, you are the trusted escalation point. To customers and partners, you are the senior voice they want in the room when the stakes are highest.

Meet the job

You take lead architect responsibility on the largest and most complex programs in the region. You translate business ambition into an architecture that holds up under scrutiny: integration, security, performance, scalability, resilience, and long-term maintainability. You shape the target state, the transition path, and the trade-offs the customer needs to understand before they commit.
You work across the full deal and delivery cycle. In pre-sales you partner with Sales and Solutions Engineering to win strategic opportunities, owning the architecture story from discovery through contract. In delivery you stay engaged at the moments that matter: inception, major design decisions, and the hard problems that surface mid-program. You do not manage a team of architects, but you raise the bar for the ones around you through design reviews, reference architectures, and worked examples.

You also contribute to how Backbase sells and delivers at scale. That includes producing reference designs, patterns, and points of view that other architects reuse, feeding field learnings back to Product and Engineering, and representing Backbase architecture in senior customer forums, analyst briefings, and partner conversations. Travel is significant, especially during inception and at key program milestones.

How about you?
        •       You have a decade or more of hands-on experience designing large Java platforms in production;
        •       Spring, Maven, and a modern CI/CD toolchain are second nature to you;
        •       You have strong, experience-backed opinions on Service Oriented and Micro-Services Architectures and when each is the right call;
        •       You understand modern front-end delivery: JavaScript frameworks, MVC patterns, and REST API design including RAML and/or OpenAPI;
        •       When we ask you about architectural frameworks, you reach for them instinctively rather than looking them up;
        •       You have worked deeply with Enterprise Integration Patterns and integration frameworks;
        •       You have operational depth across application servers, databases, load balancers, and the rest of the stack that keeps a high-availability deployment healthy;
        •       You have excellent written and spoken English and can hold a room from senior engineer to C-level.

We will be extra happy if you:
        •       Have delivered solutions for large financial services organisations, especially retail or commercial banking;
        •       Have shipped at scale on public cloud (AWS, Azure, or GCP) with containers and Kubernetes in production;
        •       Are fluent in patterns like CQRS, event sourcing, and event-driven integration;
        •       Have hands-on experience with API gateways, integration platforms, and identity systems in a banking context;
        •       Have spoken at industry events or published on banking architecture topics.

Join our team at Backbase, you will work with some of the sharpest people in digital banking, on programs that matter to the banks behind them and the millions of customers they serve. If you want senior technical ownership without stepping off the tools, this is the role.

At JetBrains, code is our passion. Ever since we started, back in 2000, we've been striving to make the strongest, most effective developer tools on earth. Today, AI-powered coding agents are becoming a core part of how developers write Kotlin – and we want to make sure they write it well.

The Kotlin AI Value Stream team is responsible for how AI agents understand, generate, and improve Kotlin code across all platforms: Android, Kotlin Multiplatform, server-side, web, desktop, and others. We build the evaluation infrastructure, error analysis tools, and post-training pipelines that measure and improve agent behavior on real Kotlin developer tasks.

As a Research Engineer on this team, you'll own the end-to-end loop: Analyze how agents fail on Kotlin → build evals that capture those failures → research and implement methods to fix them → measure the improvement. Your work will directly shape how millions of developers experience Kotlin through AI coding agents.

As part of our team, you will:

Build tools for agentic error analysis

• Design and implement tooling to systematically capture, classify, and analyse errors that AI coding agents make when generating Kotlin code.
• Build observability pipelines over agentic traces – mining patterns from agent sessions in JetBrains IDEs, Junie, Claude Code, Cursor, and other coding agents.

Build evaluation pipelines

• Design, implement, and maintain evaluation pipelines that measure Kotlin code generation quality across dimensions, including correctness, idiomaticity, build success, framework usage, and test coverage.
• Build simulation environments where coding agents can be measured on realistic Kotlin developer tasks – from greenfield KMP projects and Gradle dependency management to migrating Spring applications from Java to Kotlin.
• Own evaluation infrastructure: metrics, experiment tracking, automated regression checks, and reproducible benchmarking.

Research methods for improving agent and model behavior on Kotlin

• Experiment with post-training techniques (SFT, DPO, GRPO) to improve how models handle Kotlin-specific patterns, idioms, and frameworks.
• Investigate context engineering approaches: CLAUDE.md/AGENTS.md files, compiler-as-verifier feedback loops, Kotlin LSP integration, and MCP-based tooling.
• Run experiments to measure impact: A/B comparisons, benchmark suites, and before/after analyses on real codebases.
• Collaborate with model providers (Anthropic, OpenAI, and Google) to translate Kotlin-specific findings into model improvements.

Build public Kotlin benchmarks

• Design and build open-source benchmarks that measure AI coding agent performance on Kotlin tasks and eventually become the standard reference for the ecosystem.
• Create task datasets covering the breadth of Kotlin usage: the server side (Spring, Ktor), multiplatform projects (KMP), build systems (Gradle), Android, library development, and others.
• Include both mined real-world tasks and carefully designed synthetic tasks that test specific Kotlin capabilities.
• Maintain and evolve benchmarks as models improve, ensuring they remain challenging, relevant, and contamination-resistant.

We'll be happy to have you on board if you have:

• Hands-on experience building evaluation or analysis pipelines for LLMs or AI coding agents in a research or production setting.
• Strong Python engineering skills (at least three years), with the ability to write clean, maintainable code in data-heavy and ML-adjacent codebases.
• Experience with data analysis at scale: querying large datasets (SQL/Athena), building data pipelines, and performing statistical analysis of experimental results.
• The ability to own projects end to end – from identifying a problem in agent traces to designing an eval, running experiments, and shipping a fix.
• A product-aware mindset: You care about how agents are actually used by developers and can translate real failure modes into evaluation and training work.
• Familiarity with Kotlin or a strong willingness to develop deep Kotlin expertise (you'll be living in Kotlin codebases daily).

Our ideal candidate would also have experience with:

• Post-training LLMs: SFT, RLHF, DPO, GRPO – either hands-on training or designing the data and reward pipelines that feed into training.
• Modern deep learning frameworks (PyTorch) and LLM training stacks (TRL, verl, Megatron, or similar).
• AI agent development: tool-using agents, multi-step coding workflows, agentic frameworks.
• Evaluation frameworks and tools: Inspect AI, Promptfoo, LM-evaluation-harness, or custom eval pipelines.
• Experiment tracking and observability: Weights & Biases, MLflow, Langfuse, or similar.
• The Kotlin ecosystem: Android, Gradle, KMP, Spring, Ktor – with an understanding of the developer workflows that agents need to support.
• Contributing to or maintaining open-source projects, especially benchmarks or evaluation tools.

Don't check every box? That's okay – if you're excited about this work and bring strong fundamentals, we'd love to hear from you. We're happy to talk and provide the training you need to grow into the role.

As a full-stack software engineer, you will take ownership end-to-end: from requirements gathering through production delivery, balancing quality, testability, and speed of delivery. 

Responsibilities:

• Design, build, test, deploy, and maintain internal Java/Spring Boot services, supporting HR/training/recruiting/finance workflows.
• Test, build, deploy and maintain frontend applications using React / Next.js in TypeScript
• Build and operate services in AWS, including monitoring, alerting, and incident response participation (as applicable).
• Implement infrastructure as code using AWS CDK (Cloud Development Kit), including secure-by-default patterns.
• Partner with internal stakeholders (People/HR/Training/Recruitment/Finance) to gather requirements, clarify priorities, and iterate on solutions.
• Drive quality through unit tests, integration tests and performance testing
• Contribute to engineering practices: CI/CD improvements, observability, documentation, and shared platform patterns.

Skills and experience (required)

• 3+ years software engineering experience delivering production systems end-to-end (requirements => production ownership).
• Strong Java skills (typically Java 11+; align with team standards).
• Strong Spring Boot experience building APIs and services.
• Solid grasp of modern front-end frameworks – ideally React.js
• Hands-on AWS experience running services in cloud environments.
