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.

This is a role for engineers who care about velocity and solving real customer problems. You won't just ship code - you'll own projects end-to-end, make core product and technical decisions, and shape the trajectory of the company. We don't have PMs. As a Product Engineer you'll manage features across the entire product lifecycle: deciding what to build, making trade-offs on what not to ship, and polishing features until they're genuinely delightful to use. If you're an engineer who has always wanted to move into product, or a PM who wants to go back to building - this is for you.

Location: Berlin
Employment Type: Full-time
Location Type: On-site in Berlin
Level: Mid-Senior Level

About the company
Every 10 minutes, 18 million conversations happen between businesses and consumers around the world. For decades, the consumer side of those conversations sucked: long queues, robotic menus, repeated explanations, and unhelpful advice. Most people today still can't simply say what their problem is in natural language when communicating with businesses.

AI changes that. For the first time, companies can have natural conversations with customers at massive scale. Every B2C company - from energy providers to telcos to insurers - will use AI agents to talk to their customers. The number of conversations businesses will handle is going to explode in the coming years.

We're solving the challenges that come with that shift. Leading B2C companies like Sky are already using our platform to deploy thousands of voice agents and deliver a genuinely new customer experience. Building a first voice agent is easy - getting it to drive real outcomes for customers and businesses is the hard part. We help companies build, deploy, and improve consumer-facing AI voice agents at scale. This will become one of the most important software categories of the next decade.

We are a small, AI-pilled team that likes to solve hard problems. In engineering, product, or GTM - we build, experiment, and move fast, while heavily leveraging the capabilities of AI models. We take real ownership, challenge ourselves, and keep a low-ego culture.

What we look for
Velocity - everything you do, you do with speed
High Agency - "I'll figure it out" mentality
High Ownership - nobody has to tell you what to do; you just do things
First Principles Thinking - you don't take what people say at face value; you understand the underlying problem
AI-pilled - you heavily leverage AI in your work
Comfort with ambiguity - you can jump into novel, ambiguous problems, understand the root cause, and solve them
Team thinking - you optimise for the engineering org's output, not your own
This probably isn't for you if
You prefer a remote-first environment
You want to be told exactly what to do
You mostly care about the tech, not business outcomes
You want to work 9-5

Ideal candidate
We need a full-stack engineer with a product-owner mindset, extreme velocity, and a high sense of agency. The ideal candidate has a proven track record of owning projects end-to-end, translating customer problems into solutions, and making pragmatic trade-offs. While the stack is TypeScript and Python, strong engineering fundamentals and a 'figure it out' mentality are far more important than specific language experience. Without evidence of high ownership and a bias for action (e.g., side projects, startup experience, key player in past roles), do not proceed. The culture is intense and built for those who want to be fully immersed. They expect new hires to ship to production on day one and have no code reviews to maximize speed. The team works in-person, often in pairs, and values acting quickly and fixing things later. This is not a typical engineering role; it's for someone who thrives on extreme ownership and velocity in a high-stakes startup environment.

Perks
Very competitive pay + equity package (€85K-€160K)
Access to any AI tools
Free dinners if you stay late
Urban Sports Club membership
Relocation support if you're not already in Berlin

Interview process
1. Screening call with recruiter (can be skipped by Telli for strong candidates).
2. Live online coding challenge with a reverse system design component.
3. Full-day on-site in Berlin (9:00–15:00) covering system design, coding, product thinking, and a 90-minute 'top grading' career deep-dive.
4. Reference calls with contacts provided by the candidate during the on-site interview.

Note: Strong candidates with excellent references may be invited directly to the on-site stage.
