Moodsonic uses sound to improve how indoor spaces feel. Our platform delivers adaptive soundscapes for workplaces, hospitals, universities, and other shared environments shaping daily life, integrating with hardware, building systems, and an array of applications to respond dynamically to activity levels, time of day, environmental sensors, and user input. The work sits at the intersection of audio, real-time systems, and human experience.
We are hiring a Senior Software Engineer to own the backend that the entire product stack sits on: services, data layer, identity and authentication infrastructure, partner-facing integration APIs, device communication, and the security posture. You will own, evolve, and build the systems that power our internal tooling, customer-facing applications, partner integrations, and hardware deployments, strengthening what is already in production and shipping what comes next. You will be the technical lead on production engineering, security, and code quality, building on the foundations the team has put in place. As Moodsonic scales, you will keep the platform safe, reliable, and defensible. You are joining a team where colleagues hold deep domain knowledge. You will need to build trust, collaborate well, and lead through influence rather than authority. This is not a management role. The platform is live and growing quickly, with real customers and real consequences.
What you'll work on
- Own and evolve the backend platform: services, data layer, infrastructure, APIs.
- Strengthen what is in production today, design what is missing, and build what comes next.
- Own the backend side of how our deployed hardware connects to the platform: ingestion, device authentication, fleet management, and remote provisioning.
- Visibility and input into on-device code decisions, because device security is platform security.
- Own the identity, authentication, and account layer of the platform.
- Own and operate our data protection posture across the platform: encryption in transit and at rest, key management, data lifecycle, and recovery.
- Own the partner-facing integration APIs end to end, from design through operation.
- Establish and maintain the engineering standards (testing, review, deployment, monitoring, secure coding) that the team operates by.
- Partner with the engineers owning the audio engine and frontend surface on the backend contracts their work depends on.
What we are looking for
Required:
- 5+ years shipping and operating production backend systems, including time on-call and in incident response.
- Operational resilience as a habit: you design for failure, build with recovery in mind, and treat incident learning as a driver of engineering quality.
- Strong judgment in small-team environments.
- Deep relational data modeling and schema design. Postgres or equivalent as a daily tool.
- API design experience.
- Identity and authentication systems experience.
- Security mindset in practice, not theory.
- Code quality and observability as habits.
- Strong Python for backend services.
- Modern AI development tools are part of how you ship.
- Demonstrated technical leadership through influence, not authority.
- Pride in craft, proactive risk-flagging, and the instinct to raise quality bars rather than work around them.
- Clear written and verbal communication.
Valued:
- Designing systems that interface with deployed hardware.
- Shipping to enterprise customers.
- Experience inside a compliance-driven environment.
- Kubernetes and modern container orchestration.
- Additional backend language fluency.
- Audio, signal processing, or real-time systems background.
- AI and machine learning in product contexts.
Not required but welcome:
- Interest in sound, music, acoustics, or the wellbeing applications of audio.
Team and how we work
You will join a small, senior team distributed across the UK, Europe, and the US West Coast. We run a weekly product cadence, work asynchronously by default, and rely on clear written communication to stay aligned across time zones.
Compensation and benefits
Base salary £65,000 to £85,000, calibrated to experience. Equity will be a material part of the package. Benefits include private medical insurance for UK employees, 28 days paid holiday inclusive of UK holidays, flexible remote-first working. UK right to work is required.
How to apply
Send a short note, your CV, and links to work you are proud of. Please include three to five sentences on a production system, API, identity/auth, or platform hardening project you owned.
