Senior Staff Software Engineer | Voice

Senior Staff Engineer

We're looking for a hands-on Senior Staff Engineer to help lead our Voice Track. You'll drive architecture and development for our real-time voice translation systems, taking full-stack ownership from client to backend, while mentoring others and raising the bar across the teams.

This is a high-impact role for someone who combines deep system design expertise—especially in generative AI and real-time streaming—with a strong product mindset and a passion for guiding teams through hands-on leadership.

Your responsibilities include:

• Own full-stack solutions end to end: You'll design, build, and operate systems across the stack—from front-end user experience to low-latency backend infrastructure and audio pipelines.
• Lead by example: You stay hands-on, contributing production code while guiding architectural decisions and mentoring the team.
• Mentor and elevate: Grow engineering maturity through technical coaching, thoughtful code reviews, and driving best practices in observability, reliability, and scale.
• Shape product direction: Work cross-functionally with product managers, researchers, and designers to translate customer problems into impactful technical solutions.
• Scale voice infrastructure: Build systems that meet the high standards of real-time translation: low latency, high uptime, seamless UX, and ML integration.

Qualities we look for include:

• Full-stack technical leadership: You've led architecture and delivery of complex products, owning the full stack—not just backend or infrastructure.
• Deep expertise in streaming and generative AI: You understand the nuances of audio streaming, real-time systems, and generative AI systems at scale.
• Hands-on builder: You actively write code, prototype, and debug—you don't lead from the sidelines.
• Product-first mindset: You focus on user outcomes, not just technical purity. You make pragmatic decisions with long-term maintainability in mind.

Mentorship and communication: You raise others up through knowledge-sharing, clear communication, and collaborative thinking.

What we offer includes:

• Diverse and internationally distributed team: Joining our team means becoming part of a large, global community with people of more than 90 nationalities. We're more than just colleagues; we're a group of professionals with a shared mission to connect diverse cultures.
• Open communication, regular feedback: As a language-focused company, we value the importance of clear, honest communication. We value smooth collaboration, direct and actionable feedback, and believe that leading with empathy and growth mindset makes us better together.
• Hybrid work, flexible hours: We offer a hybrid work schedule, with team members coming into the office twice a week. This allows you to engage directly with your team and experience the unique energy of our workspace, while still enjoying the flexibility and comfort of working from home. With flexible working hours and trust in your productivity, we are in sync with your team's general locations and time zones to foster effective and seamless collaboration.
• Regular in-person team events: We bond over vibrant events that are as unique as our team, from local team and business unit gatherings, to new-joiner onboardings, to company-wide events that bring us all together–literally.
• Monthly full-day hacking sessions: Every month, we have Hack Fridays, where you can spend your time diving into a project you're passionate about and get the opportunity to work with other teams–we value your initiatives, impact, and creativity.
• 30 days of annual leave: We value your peace of mind. With 30 days off (excluding public holidays) and access to mental health resources, we make sure you're as strong mentally as you are professionally.
• Competitive benefits: Just as our team spans the globe, so does our benefits package. We've crafted it to reflect the diversity of our team and tailored it to align with your unique location, to ensure you feel supported every step of the way.

If this role and our mission resonate with you, but you're hesitant because you don't check all the boxes, don't let that hold you back. At DeepL, it's all about the value you bring and the growth we can foster together. Go ahead, apply—let's discover your potential together. We can't wait to meet you!
