Company mission
Safi is on a mission to improve recycling efficiency, putting an end to the unnecessary use of virgin materials.
Role
Who you are
- You have led multiple user-facing projects end-to-end, and can scope and define projects for others to work on alongside you
- You can own system design and architecture for a production product, and have examples of architectural decisions you made and the trade-offs behind them
- Deep Experience with the majority of our stack and have examples of filling experience gaps quickly
- Python
- Django and DRF
- React and React Native
- PostgresQL
- Google Cloud
- Experience monitoring reliable systems and recovering from outages
- You know how to see an alert in production and dig in to deliver a resolution
- At least 5 years in an environment where shipping fast is important
- You are comfortable delivering at pace but with strong monitoring and testing fundamentals so that software is robust and easily fixable
- Happy to travel to a customer site or our London HQ regularly (i.e. avg. once per month) (expenses covered by Safi, of course)
- If remote, timezone +/-2 hrs of London
What the job involves
- We're at an early stage with a small team. We need an experienced Staff Software Engineer / Tech Lead to deeply understand these plants and help us automate and improve them
- Own technical direction. You make the call on how core systems are designed and built, not just on the code in front of you - and you can justify those calls in terms of pace, reliability, and what the business needs next
- Raise the bar of strong engineers around you. Not via management, but via shipped work, the architecture you set, and the questions you ask in PRs and design reviews
- Have experience working with a high degree of autonomy, quickly and with a large set of competing problems to tackle (and enjoy it!)
- Have experience taking products from 0 to 1 (and then from 1 to 100!) - and have made the architectural decisions that let a system survive that transition
- Are excited about deploying technology at real-world industrial sites
- Can take a problem from "I saw something that could be improved at a plant" to a shipped feature in our app deploying at the plant, end-to-end, within a sprint or two
- Can work closely with customers - assessing (not just blindly following) what they say, observing their operations and understanding what is the critical thing to impact
- Are interested in commercial questions (how much do we charge for this?), deployment (what's the right UI for forklift engineers wearing gloves?) and AI/ML (what can we build that is 10x better than their current ERP process?)
- Can work shoulder-to-shoulder with our ML team. You don't train models but turn their outputs into something a forklift driver and a procurement manager both want to use
Application process
- Screening Call (15 mins)
- Product Challenge (1 hour with our CPO)
- Working session with our Engineers - Using your own development tools (60 to 90 mins)
- Technical Challenge - System Design and Architecture (1 hour)
- Final Chat, Q+A (30 mins)
Salary benchmarks
Our take
Safi - originally known as TrueCircle - operates the first digital B2B marketplace for the recycling industry, combining industry expertise with advanced tech to streamline recyclables trading for both buyers and sellers.
For buyers, Safi streamlines order management and supplies AI-powered quality control capabilities to ensure that users are receiving the materials they want and expect. For sellers, the platform enables the diversification of customer bases, alongside low-risk entry into international markets and optimised pricing.
As the first of its kind, Safi's platform has certainly made a splash, securing several industry notables as trading partners, such as Veolia, Pro Environmental, and Pearce Recycling. Its user-friendly, novel marketplace certainly boasts a lot of potential, especially as it services an environmentally-conscious industry on the rise.
