Overview

We are looking for a Product Owner or Senior Product Owner who is fluent in English to join our growing team and own our Speech Recognition (SR) and Text-to-Speech (TTS) products. These engines power voice agents, conversational analytics, and agent assist solutions for enterprise contact centers in 20+ countries, and are used both directly by enterprises and through partners who embed them into their own products. In this role, you will turn customer, market, and research input into a clear roadmap and backlog, working closely with engineering, R&D, QA, and customer-facing teams. If you ship fast, test early, and learn from real usage, this opportunity is for you. The level (Product Owner or Senior Product Owner) will be determined based on your experience.

Who we are

Sestek is a global technology company developing AI-powered conversational solutions that empower organizations to be data-driven, enhance efficiency, and offer superior customer experiences. We are an R&D center, and our solutions are developed by a team of over 100 engineers specializing in text-to-speech, speech recognition, natural language processing, and voice biometrics technologies. As of 2022, we are part of Unifonic, a leading Communications Platform as a Service (CPaaS) provider, and we have grown into an international organization with over 500 dynamic team members. We have a customer base of 500 enterprises across 20 countries in the US, EU, and MENA regions.

What we expect

• Ship MVPs fast and improve them with real user feedback.
• Run experiments and make decisions based on results rather than long analysis.
• Work with partners to understand how end users use our voices and speech models.
• Own the SR and TTS backlog, write user stories and acceptance criteria, and prioritize by customer and business value.
• Run sprint ceremonies with your scrum team and keep the Azure DevOps board and product documentation up to date.
• Work with R&D to turn new models into product releases.
• Define quality targets with R&D, including accuracy (WER), naturalness (MOS), and latency.
• Collect needs from internal product teams, as Agentic AI, Agent Copilot, and Conversational Intelligence all depend on your products.
• Support Presales on RFPs and technical questions, and support the PS and Support teams on customer issues.
• Build the roadmap with your team lead, covering new languages, new voices, and on-prem and cloud deployment.
• Track competitors and open-source speech models.
• At Senior level: drive speech strategy across all products.
• At Senior level: lead customer escalations.
• At Senior level: guide junior team members.

Who we are looking for

• BSc in Computer, Software, Electrical/Electronics Engineering, or a related field.
• Product Owner level: 1+ years as a PO, PM, business analyst, or software engineer at a software company.
• Senior Product Owner level: 4+ years of total experience, with at least 2 years as a PO or PM.
• Experience in a fast-paced environment such as a startup, a scale-up, or a B2C or B2B2C product.
• A bias for action: you prefer a working prototype over a long spec and make fast decisions with the data you have.
• Hands-on Scrum experience: you have owned a backlog and run sprints.
• Working knowledge of REST APIs and webhooks, and the ability to test an API with Postman.
• Advanced English (written and spoken).
• Clear communication with both technical and business teams.

We're also looking for

• A strong can-do attitude and a hands-on, solution-oriented approach: you see what needs to be done and take action.
• A strong sense of ownership and accountability: you take responsibility, follow through, and don't wait to be told what to do.
• A flexible and collaborative mindset: you enjoy working across teams and are willing to contribute beyond your core responsibilities when needed.
• A willingness to roll up your sleeves, step in where needed, and help the team get things done, even when it falls outside your usual scope.

Nice to have

• PSPO I certificate (expected within 6 months for Senior Product Owner hires).
• Coding experience in a software team.
• Experience with speech or ML products such as SR, TTS, voice AI, and LLMs.
• Understanding of model evaluation metrics (WER, MOS, latency).
• Knowledge of the contact center or customer service industry.
• Experience with AWS, Azure, or Kubernetes-based deployments (cloud and on-prem).
• Experience with developer platforms, APIs as a product, or partner ecosystems.
• Daily use of AI tools in product work.
• Arabic language skills (not mandatory, but a strong advantage).

What we can offer you

• A chance to be part of a company specializing in artificial intelligence, where you'll work on real products with real impact.
• Flat organizational structure and an energetic team that moves fast and values your voice, so you own outcomes, not just tasks.
• Freedom to try new ideas and build your own solutions, in a culture where failing fast is fine as long as we learn from it.
• Flexible/hybrid working style with the option to work from our İstanbul or Ankara office.
• Private health insurance, meal card, and transportation allowance.
• Incentive for graduate and postgraduate studies.
• Training opportunities for technical and personal development, and support for certificate programs related to the field, in a culture that encourages you to stay curious and keep learning.
• Budget for external activities with your colleagues, organized by the Sestek Social Activity Committee.
• Birthday celebrations, parties, happy hours, and seasonal events.
• Breakfast and healthy snacks available all day long in the office.
