Job description

Osprey Flight Solutions · Full-time · Remote, home-based · Reports to Head of Engineering

Why this role, why now

Aviation security teams and airline operators make real decisions off what Osprey's platform tells them, so the software behind it has to be right. You'd join a lean, six-person engineering team spanning front-end, back-end and DevOps/platform, small enough that what you build actually ships, rather than queuing behind layers of process.

We've recently closed a £40 million growth investment and are building out engineering to match, so you'd be joining while the codebase and the team are still small enough to shape. This is a genuinely remote role, not remote-with-conditions.

What you'll be doing

• Play a key role in delivering new product capability as part of a small team that ships on time, at quality.
• Support what's already live: investigate and resolve support desk issues within SLA, and own contained pockets of technical debt, escalating the harder cases to technical leadership.
• Give informed estimates on everything from fully scoped work to raw ideas, and flag blockers early rather than sitting on them.
• Help shape what gets built next, contributing to PRDs, technical feasibility testing and prototyping during discovery.
• Design solutions that fit Osprey's reference architecture, and take the more complex proposals to the technical design authority.
• Break work into small, shippable pieces with your team, and take planned production changes through change management, so you can show you release safely.
• Support less senior engineers around you, and bring genuine empathy for how end users actually use what you build, backed by solid test automation.
• Work closely with Data Science, Data Engineering and DevOps when a deliverable calls for it.

What you'll bring

• Commercial full-stack development experience; Osprey's stack centres on .NET, C# and React.
• Experience delivering in an Agile, SaaS environment.
• A track record of adapting well when priorities or requirements shift.
• Clear, concise communication, written and verbal.
• Comfort working independently and delivering sustained value with minimal supervision.

Even better if you have

• Exposure to aviation, security, InsurTech or another data-intensive B2B SaaS domain.
• Experience mentoring or supporting less senior engineers.
• Comfort presenting technical proposals to a design authority or similarly rigorous review process.

A summary of what’s on offer

• Holiday: 25 days’ paid annual leave plus bank holidays.
• Pension: Osprey matches your contribution at 4% of gross basic salary (on top of your own 4%) via the Smart Pension scheme, with an optional salary sacrifice arrangement that saves on National Insurance for both sides.
• Private healthcare: Comprehensive AXA cover from the end of probation, including inpatient/day-patient treatment, cancer cover, a 24/7 virtual GP, a health support line, and cashback on dental (up to £400/year) and optical (up to £200/year) costs.
• Life insurance: A tax-free lump sum of up to 4x basic salary from the end of probation, with an employee assistance programme, virtual GP access and will-writing support.
• Financial wellbeing: Free access to Lifetime, a financial coaching app with a personal wellbeing coach, an annual financial plan and educational tools, plus optional access to a regulated financial advisor.
• Family-friendly policies: Maternity, paternity/secondary carer, adoption and shared parental leave, fertility and IVF support, flexible working, and carer’s/emergency leave.
• Other perks: Cycle to Work scheme, an eyecare contribution through the AXA plan, professional membership and subscription fees paid where relevant to the role, and a £1,500 referral bonus once the person you refer completes probation.
