Key Skills for This Role
Full Job Posting
Is this role a fit for you?
You are motivated by impact. You thrive on transforming complex AI systems into products that developers love to use. You think holistically about architecture, user experience, and business outcomes, and you take pride in delivering systems that are both elegant and dependable.
You are equally comfortable designing APIs, building scalable backend services, and improving developer-facing experiences. You set a high bar for quality, mentor others to reach it, and drive alignment between product ambition and technical reality.
What this role could entail
Lead the design and implementation of core systems powering Runware’s AI platform
Build and evolve backend APIs, SDKs, and developer tools that make AI integration seamless
Integrate and optimise image and video models while supporting new modalities such as audio and custom LLMs
Architect scalable, reliable systems for inference orchestration and workload optimisation
Partner with platform and infrastructure teams to drive performance, reliability, and observability improvements
Shape technical direction through architectural discussions and long-term planning
Mentor engineers through code and design reviews, fostering technical excellence and growth
Contribute to documentation, tooling, and SDKs that enhance the overall developer experience
Drive initiatives that improve how we build, deploy, and maintain our platform
Requirements
- Deep experience building distributed and high-performance systems
- Strong programming skills in PHP or Go
- Proven track record of designing and delivering scalable backend systems and APIs
- Understanding of asynchronous workloads, queues, and streaming data
- Experience working with cloud and bare-metal infrastructure
- Excellent grasp of system design, performance optimisation, and scalability principles
- Clear communicator who leads technical projects and collaborates effectively across teams
- Passionate about mentoring others and raising engineering standards
- Proactive problem-solver who balances short-term progress with long-term vision
- European time zone
Benefits
- We’re a remote-first collective, meeting in person twice a year to plan, brainstorm, celebrate wins, and enjoy some face-to-face time. We have core hours for cooperative working and calls, but outside of that your calendar is yours. Work the hours that let you perform at your peak while also building a healthy life.
- We move quickly and hold a high bar, but we also believe sustainable performance matters. After major releases and milestones, we create space for the team to properly unplug, recharge and come back with the energy to tackle what's next.
- Generous paid time off – vacation, sick days, public holidays
- Meaningful stock options – share in the upside you create
- Remote-first setup – work from home anywhere we can employ you
- Flexible hours – own your schedule outside core collaboration blocks
- Family leave – paid maternity, paternity, and caregiver time
- Company retreats – twice-yearly gatherings in inspiring locations
