This is a hands-on maintenance and feature-development role within a large production codebase built primarily with Kotlin, Java, RxJava 3, XML, ViewBinding, and a custom BLE stack.

The core requirement for this position is practical commercial experience combining:

• Android BLE;
• RxJava/RxAndroid;
• the classic Android View system: XML, ViewBinding, and custom views.

The main application uses RxJava 3 rather than Coroutines/Flow as its primary reactive stack. Jetpack Compose is currently used only in the Wear OS application. This is an established legacy product, not a greenfield Compose project or a full application rewrite.

In this role, you will

• Maintain and further develop a mature native Android application;
• Investigate crashes and production issues using Firebase Crashlytics;
• Implement new features and support new Android versions and devices;
• Work with a custom BLE protocol stack across several generations of physical devices;

• Improve connection management, reconnect logic, connection stability, background operation, and foreground services;
• Support DFU/OTA firmware updates;
• Maintain WebRTC audio and video calls, real-time chats, encrypted data storage, and the Wear OS companion application;
• Support Media3/ExoPlayer and Spotify integrations;
• Manage releases through Google Play, Firebase App Distribution, and alternative distribution channels;
• Support different product flavors, regional builds, and white-label configurations;
• Update dependencies, improve legacy code, reduce technical debt, and introduce unit tests;
• Participate in code reviews and collaborate with development and QA teams.

Required experience and skills

• 5+ years of commercial native Android development experience;
• Strong Senior-level ownership and the ability to work independently with a large production codebase;
• Expert knowledge of Kotlin;
• Ability to read, understand, and modify production Java code;
• Strong hands-on commercial experience with RxJava, preferably RxJava 3, including RxAndroid;
• Strong practical knowledge of the classic Android View system: XML layouts, ViewBinding, and custom views;
• Practical commercial Android BLE experience;
• Experience with GATT services and characteristics, including read/write/notify operations;
• Experience with BLE connection management, reconnect logic, background restrictions, foreground services, and connection stability;
• Experience with Hilt or Dagger 2;
• Experience with Room and Android Navigation Component;
• Experience maintaining large multi-module Gradle projects;
• Understanding of build variants, product flavors, and complex build configurations;
• Experience with the Google Play release lifecycle;
• Experience maintaining and debugging production applications;
• Ability to investigate issues and make technical decisions without constant supervision;
• English level B2 or higher.

As a plus

• RxAndroidBle or similar BLE libraries;
• OTA/DFU experience, including Realtek/RealSil or similar solutions;
• WebRTC, audio/video calls, and audio-routing experience;
• Wear OS and Jetpack Compose experience;
• End-to-end encryption, Olm/Matrix, or SQLCipher;
• Media3, ExoPlayer, or MediaSession;
• GitLab CI and fastlane;
• Firebase App Distribution;
• Experience distributing Android applications outside Google Play;
• Experience supporting applications for the Chinese market.

Product Engineer

AI-Enabled Products · Full-Stack · End-to-End Ownership
 Fully Remote (Europe preferred)
 Independent Contractor · 50–70% initially (ramping to full-time within 6–12 months)
 Reports to Founder & CEO

You’re Not a Cog. You’re the Engine.

Most engineering roles give you a ticket queue. This one gives you a product.

At Informed Decisions, you’ll take real ownership over how a meaningful B2B SaaS platform gets built- from architectural decisions to AI integrations to what ships on Friday. You’ll work directly with the founder, with real influence over technical direction, and you’ll see the impact of your work in how organizations hire and how people’s careers unfold.

If you’ve been waiting for a role where your judgment actually matters, this is it.

What We’re Building

Hiring is broken in ways most companies don’t even measure. Informed Decisions addresses this by combining IO psychology with data-driven product design- including statistical models, analytics, and AI-enabled capabilities- to make interviews fairer, more consistent, and truly predictive of on-the-job success.

We help organizations improve interviewer skills, reduce bias, and connect hiring decisions to real post-hire outcomes. The product is live, the problem is real, and the work is technically interesting.

What You’ll Own

This is a full-stack product engineering role. You’ll work across the system with .NET and Python on the backend, APIs and integrations, AWS infrastructure, and AI-enabled workflows embedded into real product features.

Your first major responsibility is taking full ownership of a live, production product- from database and backend services through APIs and application layers- currently developed with an external vendor. This includes deeply understanding what’s been built, identifying what needs to evolve, and establishing the engineering practices and standards that will carry the platform forward.

This is an active system with real users, real data, and real consequences. We’re looking for someone who can navigate this transition with technical rigor, sound judgment, and a strong sense of ownership.

On the product side, you’ll design and ship features end to end. That means writing the code, making architectural calls, defining what “done” looks like, and owning production quality.

On the AI side, you’ll build workflows that integrate LLMs and AI services into the product in ways that are reliable, observable, and grounded in measurable hiring outcomes.

Beyond the core platform, you’ll make judgment calls about when a customer need belongs inside the platform and when a standalone tool or application is the right answer- and then you’ll build it.

Engagement Model

This role starts as an independent contractor engagement, scoped at approximately 50–70% capacity.

The intent is to increase scope and ownership over time, with a planned ramp toward full-time (100%) involvement within 6–12 months, based on mutual fit, impact, and company needs.

You’ll Thrive Here If…

• You’ve shipped production systems and can show your work through code, products, or a real portfolio
  
   
• You’re comfortable owning decisions when there’s no one to escalate to
  
   
• You’ve worked with .NET and Python in real production environments
  
   
• You’ve integrated AI or LLM services into live products, not just prototypes
  
   
• Remote-first work suits how you operate- you create structure rather than relying on it
  
   
• Your English is fluent (spoken, written, and reading), strong enough to communicate technical decisions clearly across time zones
  
   

Experience with early-stage SaaS, third-party integrations, and complex systems is a strong advantage. The tradeoffs are real, and the work reflects that.

Why This Role, Why Now

• Direct line to the founder, with real influence on product direction
  
   
• Work tied to measurable outcomes: fairer hiring and better decisions
  
   
• A remote environment built on trust, not surveillance
  
   
• High ownership from day one across a technically deep and socially meaningful problem
  
   

How We Evaluate

We don’t screen on credentials. We evaluate based on what you’ve built and how you think. Come ready to show your work.

Informed Decisions is fully remote and welcomes contractor applications from across Europe.

The Role
Our standard delivery model splits work across a business analyst, a system analyst and team lead, developers, and testers. We are looking for a rare engineer who can own that entire cycle end to end — gathering requirements, shaping the technical solution and specification, building it across backend, frontend, and mobile, and testing it properly — using modern AI tooling as the force multiplier that makes this possible.

This is not a "prompt engineer" role and it is not a traditional full-stack role. It is a full-cycle builder who has genuinely internalized AI-assisted development: someone who uses coding agents, LLM APIs, and AI-driven testing daily to compress what used to take a team into what one strong, AI-fluent engineer can deliver — without sacrificing quality, security, or maintainability.

You will work directly with the CTO and product stakeholders, take an idea from a vague business need to a shipped, observable, production-grade feature, and set the standard for what AI-native engineering looks like at Billease.

WHAT YOU'LL DO:
Discovery & requirements
- Engage business stakeholders directly to elicit, clarify, and document business requirements.
- Turn ambiguous problems into clear, testable requirements — using AI to accelerate research, drafting, and gap analysis.

Solution design & specification
- Produce technical solutions and specifications: data models, API contracts (OpenAPI), service boundaries, sequence and architecture diagrams.
- Make sound architecture decisions aligned with our microservices, event-driven, and security-first principles, and document the trade-offs.

Build (backend / frontend / mobile)
- Implement backend services in Python and/or Golang on PostgreSQL, with appropriate messaging (Kafka) and caching.
- Build web frontends (Vue/Nuxt or React) and, where needed, mobile features (Android/Kotlin, iOS/Swift).
- Write reusable, testable, efficient code, using AI coding agents to move fast while keeping the codebase clean and reviewable.

Test & quality
- Design and execute meaningful test coverage — unit, integration, API, and end-to-end — leveraging AI-assisted test generation and review.
- Own quality end to end: you are the developer *and* the tester, and "done" means verified.

Ship & operate
- Deliver through our CI/CD pipelines and infrastructure as code.
- Build observability in at design time (metrics, logs, tracing) and support what you ship.

MUST-HAVE QUALIFICATIONS:
Mandatory: demonstrable, hands-on experience with a range of AI tools in real development work. This is the non-negotiable core of the role — we will ask you to show concrete examples of what you have built and how AI changed your workflow and output.

Real, current experience with AI development tooling, such as:
- AI coding agents / assistants (e.g. Claude Code, Cursor, Copilot, or similar) used to deliver production work, not just experiments.
- Working directly with LLM APIs (e.g. Anthropic, OpenAI) — prompt design, structured outputs, tool/function calling, and agentic workflows.
- AI-assisted testing, code review, documentation, and requirements/spec generation.

Full-cycle software engineering experience — you have personally taken features from requirement to production, not only implemented tickets handed to you.
- Backend proficiency in Python and/or Golang, with solid PostgreSQL and SQL skills.
- Frontend capability with a modern framework (Vue/Nuxt or React).
- Ability to write clear specifications and communicate effectively with both technical and non-technical stakeholders.
- Understanding of microservices, REST/API design, event-driven patterns, Git-based workflows, and CI/CD.
- Security- and quality-conscious mindset; comfortable owning testing and operability of your own work.
- Self-directed, high-ownership, and able to deliver under real deadlines.

NICE-TO-HAVE
- Fintech / financial services experience — lending, payments, digital banking, or regulatory-aware development (a strong plus).
- High-load / high-scale systems experience — performance tuning, partitioning, caching strategies, and designing for reliability under load.
- Mobile development experience (Android/Kotlin, iOS/Swift).
- Cloud-native and DevOps exposure: AWS, Kubernetes, Terraform/Ansible, Kafka, and observability tooling (Prometheus, Grafana).
- Experience integrating AI features into products (chatbots, voice, document/image processing, RAG, or automation).

HOW WE WORK
- Stack: AWS, Kubernetes, Python & Golang, PostgreSQL, Kafka, Vue/Nuxt & React, Android/iOS, Terraform/Ansible, GitLab CI/CD.
- Principles: clear and maintainable architecture, security-first, scalability and reliability, high observability and automation, cloud-native and microservices-oriented design, and a strong focus on performance, resilience, and operational excellence.
- AI-native by default: we expect AI to be part of how you think, design, build, and test — used deliberately and responsibly.

WHAT SUCCESS LOOKS LIKE:
Within your first few months, you independently take a real business need through the full cycle — requirements, spec, implementation across the relevant layers, tests, and a production release with observability — at a speed and quality that would traditionally have required a small team, and you help the rest of engineering raise its AI fluency along the way.
