• Work closely with the Product Manager to align sprint priorities, success metrics, and expected outcomes;
• Balance business priorities with technical needs to ensure sustainable product evolution without accumulating technical debt;
• Actively participate in sprint ceremonies: refinement, planning, demos, and retrospectives, providing context and clarity to the team;
• Ensure the team clearly understands not only what needs to be built, but why it matters for the product and users;
• Analyze the impact of delivered features using data (adoption, usage, conversion, error rates) and adjust priorities accordingly;
• Communicate status, risks, and expectations clearly to the Product Manager, PMO, and stakeholders;

• Foster a collaborative culture with engineering teams, respecting technical expertise and supporting joint decision-making.

   

You have these superpowers

• Strong communication skills and the ability to align business expectations with delivery realities;
• Confidence in working with tools such as Jira, Confluence;

• Ability to balance user value, business priorities, technical constraints, and realistic delivery scope.

   

What We Value in a Product Owner

• You are a product leader, not just a task manager — you see real business and user value behind every user story;
• You translate strategy into action and help the team understand not only what to build, but why;
• You are the single gatekeeper of requirements, protecting the team from chaos and constant context switching;
• You build trust between product and delivery teams, fostering shared ownership and collaboration;
• You understand both business and technology and help find the right balance between value, risks, and technical reality;
• You think in data, not assumptions — decisions are driven by results and impact;
• You stay fully in context — you know the state of your product, sprint progress, and how each step moves the product toward its goals;

• You collaborate closely with the Product Manager and PMO to ensure aligned processes, clear metrics, and a unified delivery system.

   

How We Measure Success

• The backlog is always up-to-date, prioritized, and clearly understood by the team;
• Sprint outcomes deliver tangible value that impacts the product and user experience;
• Sprint Goals are consistently achieved, and delivery metrics (velocity, completion rate, predictability) remain healthy;
• The team understands the context and purpose of their work, resulting in motivated execution without confusion or excessive clarifications;
• Communication between product, technical, and delivery functions is aligned, dependencies are managed proactively, and processes run without chaos.0

We're a growing tech startup building a customer-facing web platform and an internal AI model training platform. We're looking for a Senior Fullstack Engineer to join our engineering team and take real ownership of core systems.

This is a role for engineers — people who understand code deeply, think about architecture, and solve problems independently. Not someone who completes tasks, but someone who thinks about why they exist.

Responsibilities:

• Develop and maintain the full-stack platform (React frontend, NestJS backend, AWS infrastructure)

• Design and implement scalable backend services and APIs

• Work with Postgres RDS — design, optimize, and maintain relational data models

• Build and maintain event-driven services using SQS and microservices architecture

Independent thinking. We want engineers who trace problems to their root, understand the full flow of a system, and bring solutions — not just questions. If you read code before you Google, you'll fit right in.

We are looking for a Product Owner to join Proxet to lead the development of the new application for our customer. The Product Owner serves as the primary bridge between stakeholders and the development team. You will be responsible for understanding user needs, translating them into clear product requirements, and ensuring the delivery of solutions that align with both regulatory requirements and institutional priorities.
You will own the product backlog, guide feature prioritization, and shape the future evolution of the product through close collaboration with stakeholders, developers, customers, and end users.

Project focuses on delivering a seamless digital experience for customers and end users within the Customer’s ecosystem. The goal is to build and evolve a platform that balances operational priorities, technical feasibility, and compliance needs while acting as the "voice of the customer" throughout the development lifecycle.

SKILLS & EXPERIENCE

• 5+ years of experience as a Business Analyst and/or Product Owner on software delivery teams (Agile/Scrum/Kanban);
• Experience in Delivery/Transportation/Logistics domains.
• Proven experience owning a product backlog end-to-end from discovery through delivery, UAT, and release support;
• Strong skills in facilitating prioritization and alignment meetings with leadership and external customers (Stakeholder Management);

  Facilitate weekly prioritization meetings with product leadership to align on upcoming work.
• Requirements & Backlog Ownership
  Translate customer needs into clear, actionable delivery items (epics, stories, and acceptance criteria).
  Create and maintain a prioritized product backlog based on platform strategy and user input.
  Ensure all tickets include necessary business context and functional/non-functional details.
• Sprint & Roadmap Planning
  Define and maintain the product roadmap in alignment with leadership.
  Collaborate with development and QA teams during sprint planning to define scope and priorities.
  Participate in backlog grooming to ensure implementation readiness.
• Testing, Release & Improvement
  Coordinate and facilitate User Acceptance Testing (UAT) with stakeholders to validate compliance and functionality.
  Support release planning and ensure all user-facing changes are documented and communicated.
  Gather post-release feedback to track usability concerns and refine product priorities.

• Ability to go deep on any outbound topic in 1–2 weeks and present it credibly
• Strong communication and stakeholder management skills — you coordinate designers, partners, marketing, and sales independently
