Senior Partner Solutions Engineer

About The Role

We’re looking for a Partner Solutions Engineer to own the technical side of our partnerships; from scoping a real use case to shipping an MVP integration and enabling co-selling. You’ll be the technical counterpart to our partners and a bridge between our GTM and product/engineering teams.

What You’Ll Do:

• Work with partners to confirm the problem, the joint workflow, and what “good” looks like
• Write a short MVP spec (target: ship in 4-6 weeks), including success metrics and risks
• Design and implement auth and data flows (OIDC/SAML, OAuth, least-privilege scopes)
• Build the MVP: APIs, webhooks/polling, idempotent writes, retries, rate-limit handling, feature flags
• Stand up safe test environments (sandbox/tenant), sample data, and pass security reviews
• Instrument logging and basic health metrics; document runbooks, alerts, rollback
• Create enablement assets (solution brief, OpenAPI/Postman, quickstart, demo) and train partner SEs/AEs
• Join select late-stage calls to de-risk architecture questions and speed decisions

What You'Ll Bring:

• 6-10 years in solutions engineering, product, or technical integrations roles for B2B SaaS; you’ve delivered partner integrations end-to-end OR have 0 to 1 product experience
• Comfort with API testing and documentation, light scripting/automation, and basic monitoring and diagnostics
• Clear technical communication skills with both internal and external audiences
• Track record delivering integrations for enterprise clients with scale/complexity (multi-tenant, rate limits, uptime SLAs).
• Proven history of enabling sales and partnerships: not just “building integrations” but helping commercial teams sell them.
• Experience working in fast-moving environments where scoping, prioritisation, and resource trade-offs are key.

We’Ll Be Lucky If:

• You’ve previously worked within legal tech

What We Offer:

• Real Impact & Growth: Be part of a scaling company where your work truly moves the needle.
• Competitive Compensation: A salary package aligned with your experience and impact.
• Meaningful Stock Options: Be rewarded for growing with the company
• Annual Bonus scheme: Eligible for the company bonus scheme.
• High-Performance Culture: Collaborate with ambitious, high-calibre teammates who raise the bar.
• Private Healthcare Dental and Optical.
• Generous Time Off: 25 days of annual leave plus public holidays
• Work From Anywhere Policy: Spend up to a month a year working abroad
• Enhanced Parental Leave: Inclusive policies that support working families.
• Top-Quality Equipment: Modern tech and ergonomic setups to help you do your best work.
