BillEase

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.

The Role

We're looking for a Full-Stack Product Designer who can take ownership of complex customer problems and turn them into simple, intuitive, and scalable product experiences.

This role spans the entire product design process, from discovery and research to interaction design, visual design, systems thinking, and delivery. You'll work across multiple product areas and collaborate closely with product managers, engineers, researchers, and business stakeholders.

You won't be limited to producing screens. You'll participate in customer research, analyze behavioral data, contribute to product strategy, facilitate design discussions, and stay involved through implementation and launch.

What you'll do

• Own end-to-end product experiences, from discovery and strategy to delivery and iteration.
• Lead the design of complex customer journeys across lending, payments, cards, and financial services.
• Turn ambiguous problems into clear, simple, and scalable product solutions.
• Create flows, prototypes, and high-fidelity designs that are ready for development.
• Partner closely with Product Managers, Engineers, Researchers, and other stakeholders to shape product decisions.
• Use customer insights, analytics, and research to validate ideas and improve experiences.
• Contribute to and evolve our design system and shared design patterns.
• Ensure design quality through implementation, launch, and post-release improvements.
• Balance business goals, customer needs, and technical constraints to make sound product decisions.

• Help raise the overall quality of design through collaboration, feedback, and continuous improvement.

   

What were looking for

• 5+ years of experience designing digital products in consumer, e-commerce, mobile, or financial products.
• Proven experience owning end-to-end product experiences from problem definition to launch.
• Strong portfolio demonstrating UX thinking, interaction design, visual design, and product impact.
• Experience designing native mobile applications and mobile-first experiences.
• Ability to navigate ambiguity and independently drive work forward.
• Excellent Figma skills, including components, auto-layout, prototyping, and design systems.
• Experience designing complex workflows or transactional experiences.
• Understanding of user research, usability testing, and data-informed decision making.
• Comfortable using AI tools to accelerate research, exploration, content creation, prototyping, or design workflows.
• Strong communication and presentation skills.
• Comfortable giving and receiving feedback in a highly collaborative environment.

• Bias toward action, strong ownership mentality, and willingness to roll up your sleeves.

   

Nice to have

• Experience working in fintech, lending, payments, banking, or other regulated industries.
• Experience working in fast-growing startups or high-velocity product teams.
• Experience shipping products for emerging markets or large consumer-facing mobile applications.
• Experience contributing to design systems across multiple products or teams.
• Experience working in cross-functional, distributed, or international teams.
• Motion and interaction design skills that help create polished and engaging product experiences.
