Job Description

Role Overview and Team Mission

You will be involved in developing the application layer of our field services, creating a critical bridge between field operations and our core ERP system. Your task will be to refine high-performance web interfaces that allow technicians to synchronize data from the field in real time, ensuring reliability, performance, and fault tolerance of the system in challenging operating conditions.

Core Responsibilities:
The 70/30 Development Split

As a senior developer, you will navigate a workload focused on client-side complexity while maintaining the backend integrity of the application layer.

  • Frontend Engineering (70%): Architect complex business logic on the client side and build highly responsive, intuitive UIs. You will leverage modern web standards and tools like Webpack to ensure a seamless user experience.

  • Backend Support and Optimization (30%): Implement server-side logic adjustments using C# and .NET Framework 4.8. This is not just about maintenance; you will be responsible for high-level performance tuning, debugging multi-threaded distributed software, and eliminating bottlenecks.

  • Mobile Framework Integration: Master and utilize our proprietary framework to ensure web-standard code compiles efficiently into a custom mobile environment for field use. You will be the technical authority on how frontend code translates to mobile performance.

  • Codebase Evolution: Systematically support, optimize, and refactor the existing codebase. You are expected to proactively identify areas for reorganization to improve stability and execution speed.

AI Innovation and Future-Proofing

The Field Services team is actively integrating AI-powered features to redefine field workflows. We are not looking for "wrapper" developers who simply call APIs. You must possess a fundamental understanding of how AI technologies and models function "under the hood." Your role involves understanding model mechanics to ensure efficient integration and optimal performance within our proprietary mobile framework.

Qualifications

Technical Requirements

  • Modern Web Stack: High proficiency in TypeScript and JavaScript, with expert-level command of Webpack and modern frameworks (Angular, React, or Vue).

  • Backend Support: Strong competency in C# and .NET Framework 4.8, specifically for developing and debugging multi-threaded distributed logic to support frontend requirements.

  • Database Management: Functional proficiency in T-SQL and SQL for managing complex data interactions.

  • Software Engineering Standards: Deep knowledge of design patterns, algorithms, data structures, and clean code principles to maintain a sophisticated architecture.

  • UX/UI Intuition: The ability to independently design and evaluate user-friendly interfaces specifically optimized for technicians operating in challenging, high-pressure field conditions.

Preferred Experience

  • Advanced proficiency with performance profiling and debugging tools, specifically dotTrace and dotMemory.

  • Commercial experience with ERP or CRM systems (direct experience with Acumatica is a significant advantage).

  • Experience with version control systems, specifically Git.

Communication and Professionalism

  • Language: Fluent written and spoken English is mandatory for technical documentation and precise team communication.

  • Mindset: We operate with a professional, direct, and product-oriented mindset. You must be able to justify technical decisions through the lens of business goals and user outcomes.

Additional Information

What We Offer

  • Direct impact on a high-growth product suite and professional advancement opportunities
  • The opportunity to work with a modern tech stack and implement "under the hood" AI solutions
  • Competitive compensation package reflecting senior-level expertise
  • Private health and life insurance
  • Performance bonuses
  • Full work equipment (Laptop, mouse, headphones, etc)

All your information will be kept confidential according to EEO guidelines.

Bending Spoons

Belgrade

Apply on the employer's site

Role description

At Bending Spoons, we’re striving to build one of the all-time great companies. A company that serves a huge number of customers. A company where team members grow to their full potential. A company that functions at unparalleled levels of effectiveness and efficiency. A company that creates value for shareowners at an extraordinary rate. And a company that does so while adhering to high ethical standards.

In pursuit of this objective, we acquire and improve digital businesses, not to sell on, but to own and operate for the long term. The transformations we make are often deep—designed to speed up innovation, benefit customers, and strengthen business performance. Here, hierarchy is minimal and teams are small and talent-dense. We operate established products with the ambition, agility, and urgency of a startup. Across the company, we integrate AI deeply into how we work so that human judgment and machine intelligence reinforce each other.

For a talented, driven, and collaborative individual, working at Bending Spoons is an opportunity to learn, make an impact, and progress their career at an exceptionally high rate. That’s our promise to such a candidate.

A few examples of your responsibilities

  • Build software that matters.
    Take real ownership from idea to production, creating systems used by millions and evolving them into products at scale.
  • Amplify your impact with AI.
    Integrate the most powerful AI tools directly into your development workflow—design, implementation, testing, and documentation—to move faster while maintaining high standards for correctness, reliability, and maintainability.
  • Master your toolkit.
    Work across diverse stacks with end-to-end ownership, choosing the right technologies for each challenge. From monoliths to microservices, gRPC to REST, Kubernetes to Docker, Python to Rust—you’ll apply technologies thoughtfully, focusing on depth and purpose rather than trends.
  • Simplify relentlessly.
    Question every layer of complexity. Improve architectures, pipelines, and codebases to build systems that are simpler, more scalable, and easier to maintain.

What we look for

  • Reasoning ability.
    Given the necessary knowledge, you can solve complex problems. You think from first principles, and structure your ideas sharply. You resist the influence of biases. You identify and take care of the details that matter.
  • Drive.
    You’re extremely ambitious in everything you do—and your initiative, effort, and tenacity match the intensity of your ambition. You feel deeply responsible for your work. You hold yourself to a high—and rising—bar.
  • Team spirit.
    You give generously and without the expectation of receiving in return. You support the best idea, not your idea. You're always happy to get your hands dirty to help your team. You’re reliable, honest, and transparent.
  • Proficiency in English.
    You read, write, and speak proficiently in English.

What we offer

  • Incredibly talented, entrepreneurial teams.
    You’ll work in small, result-oriented, autonomous teams alongside some of the brightest people in your field.
  • An exceptional opportunity for growth.
    We go to great lengths to hire individuals of outstanding potential—then, our priority is to put them in the ideal position to thrive. Spooners in their 20s lead products worth hundreds of millions of dollars. And if you’ve got what it takes, you’ll soon be playing an essential role in major projects, too.
  • All. These. Benefits.
    Flexible hours, remote working, unlimited backing for learning and training, top-of-the-market health insurance, a rich relocation package, generous parental support, and a yearly retreat to a stunning location. We help each Spooner set up the conditions to do their best work.
  • A flexible start date and part-time options.
    You don't need to wait until graduation to apply. We offer flexible start dates and the possibility to begin part-time, transitioning to full-time as you complete your degree. Many Spooners joined before graduating and progressively took on greater responsibility, with arrangements that allowed them to do so without compromising their education.
  • Competitive pay and access to company equity at a discount.
    Typical annual salary offers range from £85,797 to £151,436 in London and from €66,065 to €107,837 elsewhere in Europe. The lower end of these ranges applies to candidates with little or no relevant experience, while exceptionally experienced candidates may receive offers of up to £316,052 in London or €240,330 elsewhere in Europe. Candidates offered a permanent contract may choose to receive part of their compensation in discounted company equity.

Commitment & contract
Permanent or fixed-term. Full-time.

Location
Milan (Italy), London (UK), Madrid (Spain), Warsaw (Poland), or fully remote from eligible countries.

The selection process
In our screening process, we prioritize verifiable signals of excellence, regardless of seniority. There are no preferential paths beyond what your application demonstrates, and we evaluate every candidate through the same process.

Some people hold back because they feel they lack experience or have an “imperfect” CV. If you like the role and believe you could excel over time, don’t self-reject.

All applications go through our careers page, which is the only way to be considered. If you pass our screening, you’ll be asked to complete one or more tests. They are challenging, may involve unfamiliar problems, and can take several hours. To learn more about what to expect throughout the selection process, you can find additional information here.

We set the bar high and won’t extend an offer until we’re confident we’ve found the right candidate. This is why a job may remain open for months or be reposted several times.

We consider all applicants for employment and provide reasonable accommodations for individuals with disabilities—please let us know through this form.

Before you apply
If you’ve applied before but didn't receive an offer, we recommend waiting at least one year before applying again.

Bending Spoons is a demanding environment. We’re extremely ambitious and we hold ourselves—and one another—to a high standard. While this tends to lead to extraordinary learning, achievement, and career growth, it also requires significant commitment.

To help you ramp up quickly and set yourself up for success, we expect you to spend most days in our Milan office during your first few months with us, regardless of your long-term work location. It’s the best way to rapidly absorb our company culture and build trust with your new teammates. We’ll support you with generous travel and accommodation assistance. After that, you’re welcome to work from one of our offices, or remotely from approved countries—depending on what we agree at the offer stage.

If the role speaks to you and you’re excited to give your best, we’d love to hear from you. Apply now—we can’t wait to meet you.
