Job summary

Feeld Ltd. is seeking a Staff Reliability Engineer (Full Stack) to raise the reliability and operability of our production systems across backend and mobile integration.

You will lead incident response, drive cross‑team improvements, and strengthen operational practices in a remote-first environment. You will own reliability outcomes, build observability, and mentor engineers while collaborating with product and design to balance delivery and risk.

Qualifications

• Significant experience building and operating production backend systems at scale.
• Strong TypeScript/Node.js backend experience; API and services.
• Proven incident response leadership: on‑call participation, triage, RCA with follow‑through.
• Solid observability skills: logging/metrics/tracing and actionable alerts/dashboards.
• Experience collaborating with mobile teams on mobile/backend integration.
• Demonstrated Staff-level IC leadership: influence through design reviews, technical direction, documentation, and cross‑team alignment.

Responsibilities

• Own reliability outcomes across critical backend services and their integration with mobile clients (React Native).
• Lead technical problem-solving during incidents: coordinate response, diagnose root causes, communicate status, and drive to resolution.
• Build and evolve monitoring/observability (dashboards, alerts, tracing, logging) for fast detection and diagnosis.
• Drive post‑incident reviews (blameless) and ensure learnings become durable fixes (tech changes, runbooks, automation).
• Improve engineering safety and quality: guardrails, safer migrations, feature-flag practices, rollout strategies, resilience patterns.
• Partner with product, design, QA, and engineering early to align delivery plans with operational risk and reliability needs.
• Strengthen documentation and onboarding: architecture notes, runbooks, service ownership docs, and “how we work” guides.
• Mentor engineers through pairing, reviews, incident shadowing, and pragmatic coaching on production ownership.

Job description

Feeld is building a world where everyone is more intimately connected to each other and themselves. We’re an inclusive, human‑centred product with a distributed engineering team.

We’re hiring a Staff Reliability Engineer (Full Stack) to raise the reliability and operability of our production systems across backend and mobile integration. This role exists now to improve how we detect, respond to, and prevent production incidents, and to strengthen the engineering practices (documentation, runbooks, quality bars) that help teams move quickly without compromising stability.

This is a hands‑on individual contributor role with significant cross‑team influence: you’ll lead through technical decisions, incident leadership, and pragmatic improvements to systems and process.

Team context

Reporting line: Sits on the Platform team reporting to the Head of Platform Engineering. Works closely with engineering leadership and partners day‑to‑day primarily with backend engineers.

Scope & influence: You’ll collaborate across squads to improve production ownership, reliability, and backendmobile integration patterns.

Ways of working: Remote-first, async-friendly, high trust; you’ll be expected to communicate clearly in writing and help teams adopt consistent operational practices.

What success looks like

Within your first year, you will have:

• Reduced incident frequency and/or impact through concrete reliability improvements (e.g., better alerting, safer deploy patterns, guardrails, playbooks).
• Made incident response more effective (clear ownership, faster MTTR, better post-incident follow‑through).
• Delivered improvements to backend/mobile integration that reduce breakages and production risk.
• Established (or materially improved) documentation and operational standards that other engineers consistently use.

What you will do

• Own reliability outcomes across critical backend services and their integration with mobile clients (React Native).
• Lead technical problem-solving during incidents: coordinate response, diagnose root causes, communicate status, and drive to resolution.
• Build and evolve monitoring/observability (dashboards, alerts, tracing, logging) that enables fast detection and diagnosis.
• Drive post‑incident reviews (blameless) and ensure learnings become durable fixes (tech changes, runbooks, automation, process updates).
• Improve engineering safety and quality: guardrails, safer migrations, feature-flag practices, rollout strategies, and resilience patterns.
• Partner with product, design, QA, and engineering early to align delivery plans with operational risk and reliability needs.
• Strengthen documentation and onboarding: architecture notes, runbooks, service ownership docs, and “how we work” guides.
• Mentor engineers through pairing, reviews, incident shadowing, and pragmatic coaching on production ownership.

Must-haves

• Significant experience building and operating production backend systems at scale, including debugging distributed systems and performance issues.
• Strong TypeScript/Node.js (or equivalent) backend experience; comfort working across services and APIs.
• Proven incident response leadership: on-call participation, triage, mitigation, and root‑cause analysis (RCA) with follow‑through.
• Solid observability skills: practical experience with logging/metrics/tracing and turning signals into actionable alerts and dashboards.
• Experience collaborating with mobile teams and understanding mobilebackend integration concerns (e.g., API compatibility, releases, feature flags).
• Demonstrated Staff-level IC leadership: influence through design reviews, technical direction, documentation, and cross‑team alignment.

Nice-to-haves

• React Native experience and/or strong understanding of mobile architecture patterns and release constraints.
• AWS (or similar cloud) experience and familiarity with infrastructure-as-code, CI/CD, and production tooling.
• Experience designing reliability programs (SLOs, error budgets, incident process) and running operational excellence improvements.
• Experience with PostgreSQL / Redis and performance tuning in high‑traffic systems.
• Experience in a high‑growth environment where prioritization and pragmatic trade‑offs are essential.

About us

Feeld is an independent, experimental and fully remote organisation reshaping the dialogue on dating and sexuality. The company was founded in 2014 and has evolved since to become the open, distributed structure it is now. We have a naturally agile and fluid culture. The whole team is fully remote, which means you work where and when helps you perform at your best. We regard autonomy highly and treat our organisation as a product – we iterate, improve and test things internally to see what works best for everyone.

Our culture

We believe in creating a safe work environment through humanity, fluidity, safety, transparency and progressiveness. When hiring, we look for culture add rather than culture fit.

Because we are a fully remote team, it’s especially important that we create an environment where our colleagues feel included and connected as humans.

Diversity, equity, inclusion and belonging at Feeld

Feeld promotes open-mindedness, inclusion, diversity and kindness, both in the world and among our own workforce.

We encourage and welcome applications from people with a history of marginalisation, whether because of race, gender expression or identity, sexual orientation, neurodivergence, national origin, disability (seen or unseen) or any confluence of intersectional identities.

Our goal is a barrier‑free application process and working environment. If you require further details or assistance or have any questions about this process, please let us know at [e-mail].

Compensation and perks

We are conscious of how our work and decisions impact other humans and the environment. We design our product and organisation with consideration for the wellbeing of our Members and colleagues. Feeld’s way of working is designed to proactively prevent burnout and an “always on” culture. We believe in technology and working environments that enable people to live a meaningful, fulfilled life.

Therefore, we offer our staff:

• Flexible working hours
• Unlimited paid time off
• A fully remote working situation
• Home office budget
• Learning & development budget
• On demand therapy sessions and mental health support via Spill
• In-person meet ups

Our compensation system is one of the ways we work to uphold equity and inclusion at Feeld. Just as we strive to enable honest expression on our platform, we strive for openness of information within the organization. Internally, we keep decision‑making transparent to keep each other accountable and make sure all voices are heard. That is why we offer a compensation system that is transparent, honest, and equitable. Additionally, we believe all humans deserve to earn a competitive wage, so we offer a Baseline Freedom Salary of £60,000 GBP per year for any role that indexes below £60,000 GBP per year.

Estimated compensation for this role:

• Total cash compensation for this role varies by geographic location. We estimate the market‑competitive compensation range for this position to be between £100,000 - £130,000 GBP
