Senior Backend Engineer (Product Ownership)

About Plansom

Plansom is building a category-defining execution platform for modern organisations.

As companies scale, planning breaks down, ownership blurs and execution slows. Existing tools optimise fragments of work documents, tasks, and communication but none are designed to run execution at scale.

Plansom is solving this by building a platform that becomes the execution backbone for teams: a system that connects planning, accountability delivering across people, processes and time.

We’re building software designed to help thousands of teams deliver results consistently, with AI embedded directly into how work is structured, tracked and improved.

Plansom has been featured on the Microsoft Blog for building the Plansom Agent for Microsoft Teams, powered by Microsoft Foundry SDKs and Azure OpenAI.

We are early, but deliberate: a live product, real users, weekly releases and a clear path to scale.

The Role

We are hiring a Senior Backend Engineer who has owned a product in production.

This is not a support research, or a ticket-only role. You will own backend features and product areas from specification through to production and iteration.

You will work closely with:

• The CTO and CEO, who own technical vision and architecture
• Product and frontend teams, to deliver and evolve features

The CTO and CEO set the direction. You execute, own and improve product components within that framework.

What You Will Own

• Backend features from design → build → release → iteration
• Production services written in Python and Javascript
• APIs, data flows and integrations
• Reliability, performance and code quality of the areas you own
• Continuous improvement based on real product usage

Ownership means:

• Knowing how your code works in production
• Taking responsibility for outcomes, not just delivery
• Fixing what breaks permanently and improving what doesn’t scale

“Owned a Product” — What This Means (Mandatory)

You must have personally owned at least one product or product area that:

• Was live in production
• Had real users or customers
• You were responsible for beyond initial delivery

This does not include:

• Only implementing tickets
• Only maintaining legacy systems
• Only contributing as part of a large team without ownership

If you have not owned a product end-to-end, this role is not a fit.

Required Experience

• 6–10 years backend engineering experience
• Strong hands-on experience with Python and Javascript
• Experience in product-led SaaS companies
• Proven ability to work independently and take ownership
• Experience working in remote or distributed teams
• Clear, pragmatic communication style
• Scalable REST Services
• Python libraries such as Django, FastAPI.
• Postgresql or Any SQL Database in Production
• Hands on cloud experience (Azure Prefered)
• Kubernetes, Docker & GitOps
• AIOps/MLOps (basic knowledge)
• Outstanding academic record

Nice to Have

• Experience in early-stage or scaling startups
• Cloud experience (Azure preferred)
• Experience improving performance and scalability post-launch

How We Work

• Clear technical direction
• Weekly releases
• High trust, high accountability
• Outcome-focused delivery
• Direct feedback from product and customers

Why Join Plansom

• Real product ownership without politics
• Strong technical leadership and clarity
• A live, evolving product with real users
• Opportunity to grow into Lead Backend responsibilities
• Remote-first working culture

This role is for engineers who want to build, own and improve something that genuinely matters.
