Responsibilities 
Leadership 
Context is key, as is motivation. You don't need to provide the solution to every problem, but you must make sure your team knows what their goals are, why they matter, and when we need to achieve them to fulfil our responsibility to our colleagues and clients. 
The biggest impact a team leader has is ensuring each team member understands their responsibilities and knows exactly what good looks like. Work within your team and lead by example... 
Sometimes this takes the form of being the senior developer, refining complex features into discrete stories and tasks. Other times it can be having hard conversations to ensure that we uphold high standards on everything from quality to values to office attendance. The company affords developers flexibility and ownership over their daily work, but this must be met with the respect it deserves. The Team Leader must communicate transparently and demonstrate daily the standards and behaviors we expect in return. 
Proactively identify any areas where improvements can be made, whether that is in the standards, processes, or technology in your team or the wider R&D organization. Work with your colleagues to agree the solution required and lead everyone forward to deliver. 
Subject Matter Expert 
Represent the client – immerse yourself in the product domain you are responsible for. Understand how clients use the features your team develops, what problems they are solving, and where both the industry and technology are headed. Be a vocal advocate for the users who rely on your features to do their jobs. 
Represent the team – not every colleague in Tech Org or Revenue and Customer Orgs has the same domain and technical expertise. Always keep open lines of communication for both new feature development and support inquiries and bugs. Ensure the information provided by your team is clear, concise, and shared in plain English with timescales for next steps. 
While over-communication is preferable to under-communication, our colleagues do not need to understand every problem we have solved to get to the solution. 
Senior Developer 
Most of your time on any given Tuesday afternoon (i.e. BAU) will be spent hands-on developing, collaborating, and working directly with others in the team and leading by example. Show everyone what good looks like, transparently communicating and demonstrating the standards and behaviors expected of a Senior Developer. Often this will involve refining complex features into discrete stories and tasks. 
SCRUM Master 
Run the agile process for the team. Lead the ceremonies, follow the process, and meet the Definition-of-Done. 
Use the tools in place to set the team’s priorities, update the status of all stories and tasks, and build steady, linear progress towards our goals. Lead by example and encourage developers to keep their own stories and tasks constantly updated, to avoid requests for status updates working their way up and down the chain. 
Mentor 
Leaders create more leaders. Work with your team individually to ensure their behaviors align with our values and good practice and enable them to meet their career goals via realistic expectations and an achievable 
personal development plan for everyone. 
Line Manager 
Your responsibilities include the line management and admin for your team. 
This includes regular check-ins and 1-1s, culminating in goal-setting and annual performance reviews. 
Monitor progress and provide regular feedback to help them achieve their goals. 
If you take care of the other responsibilities above and are leading by example working directly within the team, then this should only have a modest impact on time. There should be no surprises, and each team member should always be clear on what their priorities are and the expectations we have. Keep an open-door policy that team members can use for any-and-all questions arising. 
On rare occasions, this may include hard conversations where our standards, values, or just good practice are not being met. Have the courage to provide this feedback early so that corrective actions can be taken. 
The company is an ambitious, growing organization, and part of your role will include supporting our Talent Acquisition team to attract and recruit the best talent. This may involve promoting open positions and 
attending recruitment fairs and other events. You will participate in interviews to assess candidates' technical and cultural (leadership) fit for open positions across all of R&D, not just your team.
