This is a hybrid role requiring at least three days per week in our Manchester office to support strong team collaboration.

• Lead full lifecycle development of integrations that connect the Mark43 platform with external systems such as 911 call centers, state databases, evidence systems, and other key services.  
• Drive architectural decisions and ensure scalable, maintainable solutions across REST APIs, message queues, and event‑driven workflows.  
• Collaborate closely with Product, Engineering, and partner technical teams to define reliable API contracts and integration patterns.  
• Help elevate coding standards and code reviews.
• Contribute to integration testing strategies, observability, and dashboards to monitor operational data flows.
• Champion best practices for performance, security, and error‑handling in distributed systems.
• Participate in sprint planning, roadmap discussions, and technical strategy across the integrations team.

What You’ll Need

• Strong focus on backend services, distributed systems, and system integrations.
• Proven ability designing and operating APIs, webhooks, or asynchronous messaging systems
• Experience with languages and technologies relevant to our stack such as Java, TypeScript/JavaScript, RESTful services, SQL/MySQL, and data pipelines.  
• Strong communication skills and the ability to work with cross‑functional partners.

• Familiarity with CI/CD pipelines, observability tooling, and cloud‑native practices.

What We Offer 

• 28 days holiday plus UK bank holidays
• Private medical, dental, and vision insurance through AXA Health and BUPA, fully paid for you and your dependents
• 18 weeks paid parental leave for primary caregivers plus a ramp-back programme

What We Value 

• Humility. You know the best ideas win, no matter where they come from. You ask questions before making assumptions and you're as happy being wrong as being right, because either way, the team gets to a better answer.
• Inclusivity. You respect expertise in all its forms and actively seek out perspectives different from your own. You make space for others and assume good intent.
• Excellence. You care about quality in your code, your reviews, and how you communicate. You're not satisfied with "it works" when it could be better, and you encourage the same standard in those around you.
• Diligence. You take ownership, mind the details, and understand that the software we build is used in moments that genuinely matter. You don't cut corners when people are depending on the outcome.
